The official strike zone is defined as the space above home plate between the halfway between a batter’s shoulders and the top of his uniform pants – when the hitter is in his stance and ready to swing at a thrown ball – and a point just below the kneecap of a batter’s uniform pants. When the ball is in the aforementioned region, a portion of the ball must cross over a portion of home plate in order to be ruled a strike. The home-plate umpire calls strikes and balls after every pitch has past the batter, unless the hitter makes physical contact with the baseball (in which case the pitch is automatically a strike).
History of the rule
Baseball’s vertical standards for the strike zone have changed multiple times over the course of the sport’s history, with the most recent revision being introduced in 1996. Strike zones in the past
- From 1988 to 1995, the strike zone extended from the midway between the shoulders and the top of the uniform pants to the top of the knees
- From 1996 to present, it extends from the midpoint between the shoulders and the top of the uniform pants to the top of the knees. From 1969 to 1987, the strike zone extended from the batter’s armpits to the top of his or her knees, depending on the season. This strike zone, as well as the lowering of the mound from 15 inches to 10 inches, were instituted in reaction to the 1968 season, which has come to be known as the “Year of the Pitcher,” during which hurlers’ domination reached unprecedented heights. From 1963 to 1968, the strike zone extended from the top of the batter’s shoulders to the bottom of the batter’s knees. In baseball, the strike zone extended from the batter’s armpits to the top of the knees between 1950 and 1962. This particular variant of the striking zone, which was in operation from 1963 to 1968, had been in use previous to 1950, dating back to the late 1800s.
Please keep in mind that the box drawn above delineates the boundaries of the Major League striking zone.
Information about MLB’s strike zone
On the lower end, the Strike Zone is enlarged, moving from the top of the knees to the bottom of the knees, which is effective in 1996. 1988 to the present “When a player hits a ball into the strike zone, it is defined as the area above home plate bounded by an upper limit defined by a horizontal line drawn through the middle of the top of his shoulders and top of his uniform pants, and a lower limit defined by a line drawn through the top of his knees. In order to calculate the Strike Zone, the hitter’s stance must be taken into consideration as the batter prepares to swing at a thrown ball.” 1969 to the present “Assuming that the hitter adopts a natural stance, the strike zone is defined as the space above home plate between the batter’s armpit and the top of his knees while he is in a striking position.
As the hitter swings at a pitch, the umpire will assess the batter’s normal stance, which will be used to define the Strike Zone.” 1957 to the present “A strike is a legal pitch that is called a strike by the umpire if it meets one of the following criteria: (a) is struck at by the batter and is missed; (b) enters the Strike Zone in flight and is not struck at; (c) is fouled by the batter when he has less than two strikes at it; (d) is bunted foul; (e) touches the batter as he strikes at it; (f) touches the batter in flight in the Strike Zone; Note: The letter (f) was added to the previous rule and definition.”1950- “The Strike Zone is defined as the space above home plate between the hitter’s armpits and the tops of his knees when the batter adopts his natural stance.” As of 1910, “Any ball thrown by the pitcher while either foot is not in touch with the pitcher’s plate shall be deemed to have been delivered by the umpire while the bases are empty.” 1907 to the present “A fairly delivered ball is a ball pitched or thrown to the bat by the pitcher while standing in his position and facing the batsman that passes over any portion of home base before touching the ground, and that does not touch the ground lower than the batsman’s knee or higher than his shoulder before touching the ground.
One strike will be called by the umpire for each such fairly delivered ball.” “Unless struck by the batsman, an unfairly delivered ball is defined as a ball that is delivered to the bat by the pitcher while standing in his position and facing the batsman that does not pass over any portion of home base between the batsman’s shoulder and knees or that touches the ground prior to passing home base.
As stated in 1894, “A strike is called when the hitter makes an improper hit, other than a foul tip, during an attempt at a bunt hit, and the ball lands or rolls on foul ground between home base and first or third bases.” ‘High’ or ‘low’ pitches may no longer be requested by the hitter after 1887.
Once the first pitch has been delivered, the call cannot be modified.” The batter’s waist and shoulders are positioned between the pitcher’s high pitches.
Low-pitches over the plate that are between the batter’s waist and at least one foot from the ground are considered low-pitch pitches. ‘Fair’ pitches are those that are thrown over the plate between the batter’s shoulders and at least one foot away from the plate.
Strike zone – Wikipedia
A named drawing of the strike zone layered onto a picture from a game, showing a batter, catcher, and umpire, with the labeled drawing being the batter. The batter attempts to hit a baseball tossed to him by the pitcher (who is not seen in the photo), and the umpire determines whether the pitches are strikes or balls. It is the amount of space through which a pitch must pass in order to be considered a strike even if the hitter does not swing that is known as the strike zone in baseball. According to baseball terminology, the strike zone refers to the amount of space above home plate that exists between the batter’s knees and the middle of their body.
Strikes are desirable for both the pitcher and the opposing defensive club since a hitter who receives three strikes will be struck out.
It is advantageous for both the hitter and the batting team to collect balls, because collecting four balls allows the batter to take a “walk” to first base, known as a base on balls.
The striking zone consists of a volume of space, which is a vertical right pentagonal prism in shape. Its sides are vertical planes that rise up from the boundaries of the home plate to form a triangle. Specifically in Major League Baseball, the top of the strike zone is defined as a point midway between the top of a batter’s shoulders and the top of his or her uniform pants, and the bottom of the strike zone is defined as a hollow beneath the batter’s kneecap, both of which are determined from the batter’s stance as he or she prepares to swing at a pitched ball.
- The hitter swings or offers the bat in an effort to hit the pitch, which is considered a strike.
- A ball is a pitch that does not result in a strike (short for “no ball”).
- The Official Rules (Definitions of Terms, STRIKE (b)) describe a pitch as a strike if “any part of the ball goes into any area of the strike zone,” with the ball needed not to have bounced.
- Back-door strikes are defined as pitches that go outside of the strike zone but curve inward so that they enter the volume farther back (without being struck) than the pitch that traveled outside the strike zone in the first place.
In very early incarnations of the rules, dating back to the nineteenth century, it may take up to 9 balls for a hitter to earn a walk; however, the batter could request that the ball be pitched high, low, or medium to make up for this.
Originally, the term “strike” was used literally, with the hitter striking at the ball in an attempt to hit it with his bat. A hand-out is defined as “three balls being batted at and missed, and the last one being caught” in the 11th rule of the Knickerbocker Rules (first published in 1845). Because there was no negative consequence if the batter did not swing, i.e. because the called strike did not exist, hitters were accustomed to waiting all day for “their” pitch. Only at the NABBPConvention was it established a rule authorizing the umpire to impose a penalty strike in the event of such conduct: “If a striker continues to stand at the plate without striking at good balls that have been repeatedly pitched to him for the purpose of delaying the game or giving an advantage to a player, the umpire will call one strike after warning him, and if he continues, the umpire will call two and three strikes, respectively.
The same rules apply as if he had struck at three balls if three strikes are called in a row against him.” The called ball initially emerged in the rules of baseball in 1863, and it served in a similar capacity as a discretionary penalty imposed on the pitcher for delivering “unfair” balls on a consistent basis.
- Whether or not a pitch was “unfair” or whether or not a hitter was being unreasonable in his demands was entirely up to the umpire’s discretion.
- The American Association passed the first regulation that resulted in the establishment of a designated strikezone before to the 1886 season.
- If it travels over any area of the plate while at this height, it is considered a strike.
- Major League Baseball has changed the size of the strike zone on occasion in an effort to regulate the balance of power between pitchers and batters.
- Following Roger Maris’s record-breaking home run season in 1961, the major leagues expanded the strike zone to include the area between the top of the batter’s shoulders and the bottom of his knees, as shown in the diagram.
- Carl Yastrzemski would be the only player in the American League to finish with a batting average greater than.300 at the conclusion of the season.
The declining offensive numbers prompted Major League Baseball to take measures to minimize the advantage enjoyed by pitchers, including lowering the pitcher’s mound from 15 inches to 10 inches and shrinking the size of the strike zone, which were implemented for the 1969 season.
It was originally intended to be taken literally, with the batter hitting at the ball in an attempt to hit it. “Three balls being batted at and missed, and the final one caught, is a hand-out,” said the eleventh rule of the Knickerbocker Rules (1845). When a hitter chooses not to swing, there is no negative consequence, as the called strike does not exist. As a result, batters are willing to wait all day for “their” pitch, which is rare. Only at the NABBPConvention was it established a rule authorizing the umpire to impose a penalty strike in the event of such behavior: “The umpire will call one strike after warning the striker if he continues to stand at the bat without striking at good balls that have been repeatedly pitched to him for the purpose of delaying the game or giving an advantage to another player.
When three strikes are called against him, he will be subject to the same regulations as if he had struck at three different balls.” It was originally mentioned in the rules of baseball in 1863, and it served in the same capacity as a discretionary punishment imposed on the pitcher for throwing “unfair” balls on a consistent basis.
- Whether or not a pitch was “unfair,” or whether or not a hitter was being overly fussy, was completely up to the umpire’s discretion.
- During the 1886 season, the American Association passed the first regulation that resulted in the formation of a designated strikezone.
- Any section of the plate gets struck if the object is at such a height that it crosses over it.
- It has been necessary for Major League Baseball to alter the strike zone’s size on occasion in order to maintain a balanced power distribution between pitchers and hitters, although this has proven difficult.
- Denny McLain and Bob Gibson, among others, dominated batters in 1968, compiling 339 shutouts in the process.
The declining offensive numbers prompted Major League Baseball to take measures to minimize the advantage enjoyed by pitchers, including lowering the pitcher’s mound from 15 inches to 10 inches and shrinking the size of the strike zone, which were implemented for the 1969 campaign.

- If a ball knocks over thewicket, it is considered to be a strike under the rules of cricket. A single strike puts the hitter out of the game. An automatic 1-run penalty for any pitch that is out of reach of either the batter or the wicket is the closest thing we have to a ball

Understanding the Strike Zone in Baseball
The strike zone is one of the most important components of baseball, as well as one of the most highly contested subjects in the sport of baseball. Those of you who have ever spent time in a baseball dugout during a game are aware that it is nearly always possible to hear players moaning about the umpire’s strike zone. As a result of hearing concerns about the strike zone, it’s natural to question “what exactly is the strike zone in baseball?” It is customary in baseball for the strike zone to be established as the hitter is getting ready to swing at the pitched ball.
the bottom of the batter’s knee and the midpoint between his shoulders and the top of his pants).
Let’s take a closer look at the various components of the striking zone.
The Strike Zone Explained
It’s possible that even the most seasoned players will be taken aback by this regulation. On television, you can occasionally see the batter’s strike zone, although this is generally done before the batter takes their first swing at the batter’s strike zone. Because of this, it is natural for many players to believe that the strike zone is established when the batter adopts their batting stance, however it turns out that it makes no difference how the hitter takes his stance. What counts is how the hitter initiates their swing and how well they execute it.
In this case, the umpire will make a determination as to the location of the strike zone, but that determination will be dependent on how each player begins their swing.
The Width of the Strike Zone is 17 Inches
The strike zone is defined as the area between one edge of home plate and the opposite edge of home plate, measured in inches. Home plate is always 17 inches wide in baseball and softball, which means the strike zone is always 17 inches wide in both sports. When any part of the ball makes contact with any part of the home plate, a strike will be signaled. Although it may appear straightforward, in order for an umpire to determine whether a pitch is a strike or a ball, they must first draw an imaginary vertical line in their heads from either border of home plate to the other side of home plate.
If the ball lands beyond of that imaginary line, or if it does not have the proper height, the pitch is considered to be a football.
When it comes to fastballs, Major League pitchers often reach speeds in excess of 90 mph. Due to the little amount of time available, umpires must make a quick decision on whether a pitch is in or out of the strike zone.
The Height of the Strike Zone is Determined By Player Height and Batting Approach
The height of the strike zone will vary significantly from batter to hitter due to the fact that each batter has a distinct technique to striking the ball. Because each batter’s approach is different, the regulations enable the umpire to be more flexible when assessing the height of the strike zone in each situation. Examine each of the height elements for the strike zone and how they affect the striking zone.
Bottom of the Strike Zone is the Hollow Below the Knee
A strike will be called if any portion of the ball crosses the plate and rises as high as the hollow below the knee at any point during the pitch. In medical terminology, the hollow below the knee is defined as a “shallow depression positioned at the rear of the knee joint” (source:Wiktionary). In essence, this implies that an umpire will draw an imaginary horizontal line from the back of the batter’s knee to the bottom of the batter’s strike zone to identify the bottom of the batter’s strike zone.
Top of the Strike Zone is the Midpoint Between the Batter’s Shoulders and the Top of the Batter’s Pants
The umpire will draw an imaginary horizontal line across the field to mark the top of the strike zone. Although it is not necessary, in order to measure the height of that imaginary line, the umpire must first select a point midway between the batter’s slacks and his or her shoulders. Using the midway between the batter’s shoulders and top of pants, which is normally just below the center of the batter’s chest, an umpire can draw an imaginary horizontal line across the plate to indicate where the batter’s shoulders meet the top of his pants.
Strike Zone Height is Set When the Batter Prepares to Swing
In order to further complicate matters for the umpire, the strike zone is not established until the hitter begins to swing. If the umpire wants to know how high the strike zone is, he or she must first identify when the hitter begins their swing, and then decide how high the strike zone is depending on how the batter starts his or her swing. Even while the manner a hitter positions himself or herself in the batter’s box might provide an umpire a decent indication of where the strike zone will be for that batter, the umpire will not know the exact height of the strike zone until the batter begins to swing at the ball.
Does the Strike Zone Change Based on Height?
The dimensions of the strike zone fluctuate from batter to batter, with the height of each batter being one of the most significant variances. Because the height of the strike zone is defined by the location of the hitter’s knees, shoulders, and the top of his or her pants, the strike zone allows the umpire to be flexible in determining the height of the strike zone for each batter in the batting order. The height of the strike zone will vary from batter to hitter despite the fact that the width of the strike zone will remain constant during the game.
How High Off the Ground is the Strike Zone?
According to the typical adult baseball player, the bottom of the strike zone is 18 to 19 inches above the surface of the ground. The bottom of the strike zone is defined by the hollow behind the knee of the batter, and the height of the strike zone will vary from batter to batter depending on the hitter’s height.
The bottom of the strike zone for Little League players will be a little lower than the bottom of the strike zone for Major League players since Little League players are generally smaller in stature.
What is the Average Size of a Strike Zone?
After understanding a little bit about the striking zone and the various elements that influence the strike zone, it’s natural to ask what an average-sized strike zone looks like. To find out, I took some measurements of my own batting stance, which I thought could be helpful. If you are a 5’8″ baseball player, the average dimension of the strike zone is 17 inches wide by 28 inches high. In order to maintain consistency, the strike zone will always be 17 inches wide because it is proportional to the width of the plate.
MLB Strike Zone Changes
Although the strike zone appears to be a notion that doesn’t require modification, it turns out that the strike zone has evolved slightly since baseball was first played. A thrown ball that passes over home plate and lands between a batter’s shoulders and knees was initially designated as a strike zone for the Major League in 1887, according to Baseball Almanac. The strike zone regulation was changed in 1950, when it was moved from between the batter’s armpits and the top of the knees to the middle of the batter’s leg.
- It was not until 1963 that the striking zone rule was revised once more.
- Additionally, when the hitter began to swing at a pitch, the strike zone was now established.
- The strike zone rule adjustment that took effect in 1988 changed the appearance of the regulations to be more similar to what we see now.
- 1996 saw another revision to the strike zone, this time resulting in the bottom of the striking zone moving from the top of the knee to the bottom of the knee (hollow beneath the knee).
The Strike Zone in Little League
The strike zone in Little League is a widely disputed issue, just as it is in other leagues. This is especially true among parents who are in attendance at the game. Little League’s strike zone differs from those of other sorts of leagues in that it is more open and accommodating. As defined by Little League.org, the strike zone is “the region above home plate that is between the hitter’s armpit and the top of the knees when he adopts a natural stance while the batter is facing the pitcher.” When a hitter swings at a pitch, the umpire should calculate the strike zone based on the batter’s normal posture.
Specifically, the strike zone in Little League is decided to be anywhere between the batter’s armpits and the top of their knees.
In Major League Baseball, if a pitched ball is thrown towards the armpits, it is considered a ball; yet, in Little League Baseball, it is considered a strike.
What is the Strike Zone in Baseball – What is the Point?
When you’re watching a baseball game on ESPN or another network, you might see a box adjacent to the batter’s box where the hitter is standing. In a baseball game, that box indicates the batter’s strike zone for that particular hitter. So, what precisely does the strike zone box imply, why do certain umpires make incorrect calls from time to time, and other questions arise? See what I mean in the video below!
What is the Official Baseball Strike Zone?
When a batter is in the batter’s box, there is no visible strike zone that a pitcher, catcher, hitter, or umpire can see from their vantage point. The strike zone box that you see on television, on the other hand, assists spectators in visualizing a strike and a ball from a pitcher. This box is also used by the Major League Baseball to determine the efficacy of an umpire’s call of balls and strikes during a game. For strike calls, instead of a specific box being formed by a hitter’s swing height, the general strike zone is measured from the batter’s shoulders to his knees, as seen in the illustration.
However, the strike zone is ultimately up to the judgment of the umpire, which makes the rulings for balls and strikes more exciting.
The strike zone is defined as follows: the top section is defined as the midway of the batter’s armpits, the middle portion is defined as the top of the uniform pants, and the bottom half is defined as the kneecap area.
What’s the Point of the Strike Zone?
During a baseball game, the strike zone is extremely useful to both the pitcher and the batter. It is necessary for the pitcher to record outs against a hitter, thus he employs a mix of techniques to get hitters out, including making contact with the ball, calling a strike, and swinging and missing at the ball. In order for the batter to have the greatest chance of making hard contact with the ball, they will only swing when the ball is called a strike in their direction. Pitchers would throw all over the plate and not even close to the hitter if there was no strike zone, as there was in the nineteenth century.
Suppose a batter is seeking for something new and allows six consecutive pitches to go down the center of the plate.
As soon as the hitter receives his third called strike, the batter is out, which helps to expedite the game because there are 27 outs in a baseball game.
Why Do Some Umpires Have Different Strike Zones?
Home plate umpires call balls and strikes, and each umpire has a strike zone that is slightly different from the others. Some umpires have a tendency to favor the bottom of the strike zone over the top of the strike zone. In terms of strike calls, some refer to the pitcher as being more to the left and right of home plate than others. Some umpires are more accommodating to hitters than others, and so on. While the Major League Baseball analyzes every pitch and evaluates the efficacy of an umpire’s ball and strike calls, baseball players prefer a constant strike zone throughout a game, regardless of whether or not the strike zone is 100 percent accurate.
Players who argue balls and strikes are more likely to be ejected, although umpires who recognize they made a mistake may allow them to vent for a short period of time before dismissing them.
Why is the Size of the Strike Zone Not a Universal Height?
In most cases, the strike zone is 17 inches wide, give or take a few of inches, although the height of the strike zone is determined by the hitter’s height and swing. In contrast to Dustin Pedroia, who stands at 5 feet and 9 inches tall, Aaron Judge is at 6 feet and 7 inches tall, resulting in a different striking zone for him. Because the strike zone attempts to create a box based on the batter’s stance, if you watch Judge and Pedroia bat side-by-side during a baseball game, you will see two separate boxes.
How Does the Strike Zone Effect the Game?
One missed call for your team might result in a significant shift in momentum. Consider the following scenario: your pitcher throws a pitch that looks to be in the strike zone, but the umpire does not rule it a strike. Normally, that pitch would have been considered a strike three during an at-bat, but the umpire ruled it a dubious strike since it was near the bottom of the hitter’s knees. That hitter then goes on to hit a home run on the very next pitch, and the players feel cheated out of what they believe should have been a third strike.
There are several instances where the ball looks to be low or high against the invisible strike zone, yet the umpire determines that the ball is in fact a strike.
Finally, consistency is something that every batter and pitcher strives for over the course of a baseball game.
While the pitch may not have been a strike according to the K zone, the pitcher and hitter are aware that that pitch will be considered a strike throughout the game’s duration.
How Much of the Ball Needs to be in the Strike Zone?
In order for a pitched ball to be considered a strike, it must go within the imaginary strike zone at least once. In addition, the pitch can clip the corner of the box, meaning that it does not have to be completely contained within the strike zone box. However, there are occasions when an umpire may make a mistake, particularly if the pitch is aimed at the hitter’s upper-right corner of the strike zone.
Will the Strike Zone Turn to Robot Umpires?
The use of instant replay and high quality in baseball means that robot umpires will soon be able to distinguish between balls and strikes in real time. While some fans prefer that the game be called by a human, others are open to the concept of a computer-controlled bot calling strikes and balls. The Major League Baseball (MLB) will try an Automatic Ball-Strike System in Low-A baseball in 2021 as a trial program. It is unclear whether or not this will be used in the Major League Baseball, but baseball evaluates all new laws and procedures in the minors in order to perfect the concept before implementing them in the MLB.
A Brief History of the Strike Zone
Baseball strikes were not officially introduced into the game until 1858.
Although initially intended as a punishment for the batter, the strike system changed through time to become more equitable. A more defined strike zone was established for pitchers and batters to follow as the years progressed.
Conclusion on the MLB Strike Zone
The strike zone in Major League Baseball is one of those distinguishing characteristics that distinguishes it from other sports. The strike zone can be somewhat varied from one hitter to the next, much as hitters have slightly different batting stances to bat from each other. However, while the standard rule of thumb for a strike is defined as the distance between the shoulders of an opponent and the kneecap of a batter during a game, certain umpires may have a slightly different strike zone when a game is in progress.

What Is the Strike Zone in Baseball? A Thorough Explanation
A floating box over home plate during at-bats is definitely something you’ve seen if you’ve watched any baseball on television recently. When this box is filled, it represents the “strike zone,” which is one of the most significant parts of the game. You might be asking what the striking zone is at this point. The strike zone is an invisible area that exists to distinguish between pitches that are considered strikes and pitches that are called balls by the home plate umpire. In most cases, a pitch must pass a certain region directly over home plate and between the batter’s shoulders and knees in order to be called a strike.
You could be wondering how the striking zone is determined and understood, which is understandable.
What Is the Strike Zone in Baseball?
The most intriguing aspect of the striking zone is that, while there is a standard description for it in the rules, the interpretation of the zone is always evolving. Quite simply, the strike zone is the area over home plate and towards the middle of the hitter’s body that a pitcher must hit regularly in order to have any chance of being successful. From the perspective of a batter, the strike zone is the region of the field where batters encounter the majority of hittable pitches. In order to be effective, both the hitter and pitcher must receive pitches that fall within the strike zone.
A pitcher aims to hit the strike zone as much as possible, but only at the edges, where it is more difficult for a hitter to make strong contact with the ball.
Because the strike zone is technically invisible and will take on a different shape based on whatever batter is at the plate, it is unusual in that it is never consistent, even at the greatest levels of competition, which makes it even more difficult to predict.
Aside from that, various governing bodies have varied regulations regarding the striking zone, resulting in zones that change depending on the level of government.
How Is the Strike Zone Determined?
Because strike zones are ultimately up to the judgment of the umpire, they will differ from one game to the next. However, as previously said, there are definitions at every level for how they should be called. The strike zone is defined at the major league level as the space between the batter’s shoulders and beltline and the bottom of the hitter’s knees, as well as the area directly over home plate. It goes without saying that with a definition like that, there are several possibilities for interpretation.
- That point is normally located towards the bottom of a section of the jersey known as the “letters.” The letters are so named because many teams have their team or city name (or a logo) written across the chest of their jersey, which is why it is referred to as the letters.
- Because home plate is 17 inches wide, the zone must be at least 17 inches wide as well, but it is typically a few inches broader than that.
- We met with a seasoned youth baseball umpire to gain his perspective on how strike zones change as players go through the ranks.
- This tends to diminish steadily until high school, when the striking zone begins to match the borders of the college and professional strike zones in terms of size and location.
- There are a few factors to consider, including the fact that the definition of a strike zone does not specify whether the entire baseball, or only a portion of it, must pass through a specific region in order to be called a strike.
- A strike is declared when any part of a pitch crosses the plate and enters the strike zone, as defined by baseball’s rules.
- When applied to the top or bottom of the strike zone as well, this implies that two otherwise identical strike zones might suddenly differ by a few inches both up and down as well as side to side because different umpires choose to interpret the phrase differently.
- The fact that Jose Altuve is just 5’6″ tall means that his strike zone will be several inches less than Aaron Judge’s, who is 6’7″.
There’s only one problem: there’s no assurance that the umpire will make that determination. As a result, how an umpire calls balls and strikes may have a significant impact on the outcome of a game.
How Does the Strike Zone Affect the Game?
Although the precise influence that a large or small strike zone may have on a game has yet to be determined, it is generally acknowledged that the size of the strike zone can have a direct impact on the balance between hitting and pitching. A big strike zone often advantages pitchers, whereas a tiny strike zone generally favors batters. A large strike zone generally helps pitchers. There are generally some characteristics that you might develop that will draw attention to this inclination. These issues might be minimized by using a certain sort of pitcher on the mound or by designing an offense around specific characteristics, but in general, a big zone will allow pitchers to operate farther out from the middle of the plate without the danger of walking an excessive number of hitters.
- Some individuals believe that increasing the size of the strike zone causes batters to swing with a broader strike zone, which speeds up the tempo of play, however this is difficult to establish.
- According to him, supervisors would routinely advise umpires to “call a wide zone” during his initial years, when he predominantly handled games between 9-11-year-old children.
- When an umpire calls a tighter strike zone, on the other hand, batters at higher levels of baseball will frequently pick up on close pitches that are declared balls and will be less motivated to swing.
- This might result in a pitcher walking more hitters, throwing more hittable pitches out of near-desperation, or a mix of the two outcomes.
History of the Strike Zone in Baseball
The strike zone did not exist when the first set of baseball rules were drafted in 1845, which meant that a batter could not be called out on strikes and that the base on balls (a walk) did not exist at the time of the original laws of baseball. The called strike was first used in 1858, and the called ball (as well as the base on balls) were adopted in 1863, respectively. Until 1887, however, pitchers were required to accommodate batters who requested a high or low pitch, and so there was no established strike zone at all times in baseball.
- For most of the time between 1887 and 1949, the strike zone was defined as the space between the batter’s shoulders and knees.
- Since 1887, the striking zone has been increased by regulation, and the most recent instance of this occurred in 1963, when the rule was modified back to the pre-1950 rule.
- As a result, the zone was reduced in size in 1969, and it currently extends from the batter’s armpits to the tops of his knees.
- Finally, it was significantly expanded in 1996 to make the strike zone lower by designating pitches to the bottom of the knees as strikes, resulting in the modern-day iteration of the rule set.
With this information, the next time you want to shout “where was that one, blue?” you will be more confident. You now have a better understanding of whether he made the correct decision or not.
- The strike zone did not exist when the first set of baseball rules was drafted in 1845, which meant that a batter could not be called out on strikes and that the base on balls (a walk) did not exist at the time of the original laws of baseball. This was followed in 1858 by the called ball (as well as the base on balls) which were both introduced in 186. Until 1887, however, pitchers were required to accommodate batters who requested a high or low pitch, therefore there was no established strike zone at all times in baseball. Since its inception in 1887, the contemporary notion of a fixed strike zone has undergone multiple revisions until being finalized in 1996 as the official definition of the Major League Baseball strike zone. The strike zone was defined as the space between the batter’s shoulders and knees from 1887 until 1949. From then on, the regulation was altered to decrease a portion of striking zone from above the shoulders to below the armpits, and this was the case until 1962. Since 1887, the striking zone has been increased by regulation, and the most recent instance of this occurred in 1963, when the rule was modified back to the pre-1950 version. When the National League produced their second-lowest hitting average in history, and the American League hit just.230 as a total, it was dubbed “The Year of the Pitcher.” It was the lowest batting average by any league ever. Therefore, the zone was reduced in 1969 to now encompass the area from the batter’s armpit to just above his kneecap, a significant decrease from its previous size of 125 feet. When it was reduced down to its current size in 1988, it was measured from the halfway between the shoulder blades and the belt (the letters) to just over the tops of the knees. Finally, it was somewhat enlarged in 1996 to lower the strike zone by designating pitches to the bottom of the knees as strikes, resulting in the current edition. Using this information, you’ll be more prepared the next time you want to shout “where was that one, blue?” Your perception of whether or not he made the proper decision has been improved.

Calling Balls & Strikes – UmpireBible
Calling balls and strikes is fundamental to the art of umpiring baseball, and I spend a significant amount of space to it both here on theUmpireBible and on theUmpireBible Blog (see, for example,Calling BallsStrikes: The Matthew Effect). In this post, we’ll talk about two different subjects: It is essential that you study this article in conjunction with its sibling topic, Working the Plate (Working the Plate). In that post, we go over subjects such as appropriate setup, timing, and mechanics, among other things.
The Strike Zone
The strike zone is described in the rule book as a three-dimensional space above home plate that extends from a hollow at the bottom of the knee to a point “near the halfway between the top of the shoulders and the top of the uniform pants,” according to the definitions (strike zone). For the time being, let’s put off talking about the top of the zone until later. Let’s start with the “over home plate” portion of the sentence.
How wide is the strike zone?
The home plate measures 17 inches in width (Rule 2.02). An official baseball has a circumference of 2.94436644720 inches (2.94436644720 inches to be exact, but let’s just call it three inches) (Rule 3.01). Given that the definition of a strike specifies that “any part of the ball passes through any part of the strike zone” (Definitions (strike zone)), we can infer that the strike zone is 23 inches in diameter. It is important to note that the black border around the edge of the plate is not a part of the plate.
How tall is the strike zone?
The height of the strike zone is more difficult to determine since it is determined by the physical characteristics of the batter, and so the measurements fluctuate. On top of that, the upper limits of the strike zone are different in size depending on the level of baseball you are playing (let’s be honest about this). A clean zone is defined as a zone where the top is approximately one ball above the belt in upper level youth ball (players over 14) or men’s leagues. However, if you designate that zone as a zone for ten-year-olds, you’ll find yourself walking batter after batter.
And you’re probably also throwing a ball on the outside of the plate, perhaps a ball-and-a-half (but not on the inside, because you don’t want hitters to get hit) to get the game started.
The goal is to provide you with a conceptual understanding of how to adapt for age and skill level.
Some essential lessons to be learned from the artwork are as follows:
- Professional, college, high school, and higher levels of club and travel ball are all played in what I refer to as the ” Pro zone,” which is defined as anyone over the age of 15 who is playing baseball. Because of this, the top of the zone is a little lower than what is stipulated in the rule book. What I can provide as an explanation is that baseball’s tradition and culture have adjusted the written regulation to reflect a commonly recognized “real-world” perception of what the strike zone should look like. Notice that the striking zone extends upward rather than outward or downward when adjusting for age and aptitude – that is, until you reach the really young kids, who are around ten and under – and then it begins to shrink again until you reach the really old kids, who are roughly twenty and up. These ages, on the other hand, are not set in stone. Adapt to the ability level, which tends to correspond with age but is not always the case
- When required, you can extend the zone outside off the plate to accommodate the situation. Only you, the pitcher, and the catcher will be able to see it, so as long as you maintain consistency, you will not receive any complaints. You may take it off the plate anywhere from a ball to a ball and a half. But, once again, don’t give anything away on the inside since this will result in hit batters. I’ve shown a reduction in the upper limit of the striking zone for players aged 14 and younger, which is about where the rule book states (“the midpoint between the top of the shoulders and the top of the uniform pants”). It is customary for the top limit to match with the bottom of the uniform letters, although this may not always be the case. For players aged twelve and under, raise the level to just over their armpits but maintain it below their hands. By this age, instructors are instilling in their kids the importance of never touching a pitch with anything other than their hands. Make an effort to deal with it. Although it is not shown in the figure, at this level you may easily offer a ball on the outside
- Nevertheless, for the very young players, you must give quite a little. They’ve just recently graduated from t-ball and coach-pitch leagues, and it can be difficult for them to even get to the plate, let alone hit the strike zone, on occasion. In addition, many young hitters have a natural dread of the ball, which makes for an ideal formula for a walk-a-thon. You have to keep the youngsters at the plate swinging their bats, and in order to do that, you very much have to take the stance that any pitch that is hittable is a strike. Allowing a ball to be passed on the outside, passing a ball below the knees, and bringing the zone’s top up to the shoulders Believe me when I say that the coaches will appreciate your efforts. Notice that this prescription changes after you reach the All-Star tournament stage. Even ten-year-olds do admirably by the time you have the greatest players, so you’ll be closer to the 12U zone by the time tournament time rolls around. Don’t give anything away when you’re in the striking zone. You can give away strikes on the outside if necessary, but you should never give away strikes on the inside. If you do, you’ll start getting hitters hit by pitches
- Nevertheless, you must be consistent in your approach. This is something I cannot express enough. And this can be difficult to do at times. It is possible, for example, that one side has poor pitching while the other has excellent pitching. It’s tempting to provide a hand to a struggling pitcher so that you don’t end up spending the entire day walking batters, but you must avoid this urge. If you offer one pitcher some outside aid, for example, you must also give the other pitcher the same amount of freedom
- Otherwise, the game will be unfair. Never forget that the striking zone has three distinct dimensions. This will be discussed in further detail in the sections that follow. However, just to be clear, the striking zone is 17 inches deep. It is for this reason why breaking balls are difficult to predict. This is especially true for the lollipop floaters that you get from the younger children.
This is where the rubber hits the road, so to speak. Please keep in mind that this section is inextricably linked to the topic, Working the Plate, so please keep that in mind as we get started. The two are inextricably linked. One is not very useful if the other is not present. We defined the striking zone only a few lines earlier. Knowing where the striking zone is, on the other hand, is a long cry from being able to see it. So we’ve made the transition from the world of measurements and laws to the domain of the umpire’s occult powers.
The striking zone cannot be measured since it is not a physical entity.
It’s not so much the striking zone as it is the ability to recognize it.
Moreover, you learn to understand the calculus of a breaking ball that grazes (or does not graze) the zone peeling in from the top or side, or perhaps simply clips the bottom as it heads towards the ground.
When it comes to advanced ball strike calling, Peter Osborne makes an excellent case for starting at the bottom and working your way up.
I’ll confess it: I agree with Osborne on this one — the zone should be built from the ground up.
Osborne deconstructs the process of creating your zone far more effectively than I can.
Then go back and read it again.
I’m not claiming that Osborne’s counsel is infallible; rather, I’m stating that it is really well thought out.
Once again, it is a matter of being more visually aware. As well as a number of other details, such as movement of the catcher’s glove, a batter’s belt, and the position of the batter’s hands, the plate itself is depicted in the image. See the next section: Working the Plate.
