## A complete beginner’s guide to baseball stats: Pitching statistics, and what they mean

Pitching is a difficult task to master. Using a mix of at least a half-dozen pitches, each with a distinct spin rate and delivered to different positions in the strikezone, pitchers may achieve a range of results. As a result, there is an abundance of statistics that might be confusing to novice baseball fans. We will take a more in-depth look at the more sophisticated statistics later in the week, but for now, we want to make sure that all of the fundamentals are covered. Let’s start with our old buddy the box score and then move on to a few other important pitching statistics to make sure you’re prepared before we go too far into the remainder of the discussion.

ESPN provided the image.

### Pitching Basics

The value in this field shows the number of innings a pitcher pitched in a game. He tossed a whole six innings for Matthew Boyd, who is seen above. It is possible to see the innings pitch reported as 6.1 or 6.2 on occasion. These decimal points tell us how many outs the pitcher had left in the inning at that point. An innings pitched number of 6.11 indicates that a pitcher went six innings and got one batter out in the seventh inning before being relieved by another reliever. Because a third out would bring the inning to a close, you will only see a.1 or a.2.

#### Hits (H), Runs (R), and Earned Runs (ER)

Hits are treated the same way they are for a batter in this situation. Except in the case of errors and fielder’s choice, each time a hitter reaches at least first base. In our batting 101 introduction, we went into further detail about this topic. Running backs are the same as pitchers in that they signify each time the pitcher reaches home plate and scores a run on the pitching mound. It is only possible for pitchers to accumulate earned runs (ER), which signifies that the run scored was a direct result of the batter’s efforts.

Considering that these runs were not scored as a consequence of the batter’s efforts, they are called unearned runs.

For example, Matthew Boyd has 87 runs on his record in 2018, yet only 83 of those runs were earned.

#### Base on balls (BB), strikes (K), and home runs (HR)

All of these statistics are rather self-explanatory. The number of hitters who were walked, also known as base on balls (BB), indicates how many batters were walked by the pitcher. This total will include walks that are done on purpose (IBB). The number of batters that a pitcher struck out throughout the course of the game is indicated by the strikeouts. The number of home runs allowed by the pitcher is referred to as the home run total.

#### Pitch count (PC) and Strikes (ST)

This figure is only available in box scores, but it still provides some valuable insight into how well a pitcher performed in a certain game at the time.

The number of total pitches thrown by a pitcher is known as the pitch count, but the number of strikes is the number of times each of those pitches was designated a strike by the home plate umpire.

### Wins (W) and losses (L)

As we can see from the table above, Matthew Boydis was deemed the losing pitcher in this game. The letters L and 4-8 next to his name show that he suffered a defeat and that his overall season record is four wins and eight defeats. A team’s win or loss is determined by whose pitcher was on the mound for their team at the time their team gained the advantage. Alternatively, which pitcher was on the mound when the lead in the game was surrendered. For a better understanding, let’s take a look at the Rays’ side of the box score.

- Because he was pitching during the Rays’ five-run third inning, Jose Alvarado earned the honor of being named the game’s most valuable pitcher.
- Asave is represented by the ” S ” in brackets beneath Sergio Romo’s name on the team’s roster.
- Not every game comes to a close with a saving scenario.
- In the first inning, Romo entered the game with a three-run lead, which put the game in a save situation.
- Similarly, if Romo entered the game with the bases loaded with the final run on deck or at the plate, it would be deemed a successful save.
- When a middle reliever enters the game with his side leading and does not allow a tying or advancing run before passing the ball over to another pitcher, he is awarded a hold on the game.
- When it comes to player statistics, holds are rarely kept, although they are frequently indicated in a box score, sometimes with the abbreviationHLD.
- Take, for example, the 2018 National League Cy Young Award winner, who played in 32 games but only won ten of them.

### Pitching Averages

It is one of those statistics where the lower the earned run average, the more effective a pitching staff is. The earned run average (ERA) of a pitcher is derived by dividing the number of earned runs allowed (ER) by the number of innings pitched (IP) multiplied by nine (the traditional inning length of a game). As previously stated, unearned runs are not included in this calculation, which results in a more true representation of a pitcher’s success. Although the earned run average (ERA) is perhaps one of the most often utilized pitcher numbers, it is no longer considered to be the most accurate indication of a pitcher’s true skill as it once was.

Below are two examples of other commonly used pitching metrics that some say provide a more accurate assessment of pitcher quality than the ones listed above.

#### Field Independent Pitching (FIP)

A pitcher’s performance is evaluated based on his or her ability to throw without being influenced by the team’s defense. Field independent pitching attempts to remove defensive fielding factors from a pitcher’s overall performance in order to more accurately represent a pitcher’s true value when evaluated without regard to the team defense. The FIP measures elements that are under the control of the pitcher, including as strikes, walks, hit by pitches, and home runs. FIP is a useful statistic since it is represented by a figure that is virtually equal to ERA but is a more accurate measure of a pitcher’s overall performance than ERA.

While Michael Fulmer had a 4.69 earned run average and a 4.52 fielding percentage average, his genuine results as a pitcher were slightly better than his earned run average would imply.

FIP (Fielding Independent Pitching) is not a perfect measure of pitcher quality, but it is a more accurate representation of a pitcher’s individual talent than the earned run average (ERA).

#### Adjusted ERA (ERA+)

OPS+ is a similar concept. The adjusted ERA aims to account for a pitcher’s home ballpark while calculating his or her overall ERA (which can be beneficial to pitchers who work in a hitter-friendly park, and negatively impact pitchers in a pitcher-friendly park). Similarly to OPS+, the league average is set at 100, and whatever amount a pitcher gets in excess of that figure represents their percentage improvement over the league mean. Despite only having 10 victories, Jacob deGrom had an ERA+ of 216, which meant that he was 116 percent better than the league average in terms of performance.

In this case, the formula is as follows: Thanks to Wikipedia for this image.

#### Walks plus hits per inning pitched (WHIP)

You have to like a statistic whose name is so descriptive that you know precisely what to expect. Walks plus hits per inning thrown is exactly what it sounds like: it’s a formula that calculates the amount of baserunners that a pitcher allows each inning of work. The lower a pitcher’s WHIP, the fewer baserunners he or she allows on the field. The WHIP is computed by adding up all of the hits and walks and dividing the total by the number of innings pitched. A WHIP of less than 1.000 is regarded extraordinary for a season’s worth of work.

Justin Verlander finished with a 0.902 ERA (the lowest WHIP in his entire career).

OBP and WHIP are almost diametrically opposed metrics, in that the lower a pitcher’s WHIP is, the less batters are able to reach base against him.

Was that a tad too much math for you? To be quite honest, this is also true for me. In the event that this has piqued your interest and you want to learn more about pitching data, we will be performing an advanced pitching analysis later in the week.

## What does ip mean in baseball

When a pitcher’s total number of pitches thrown is divided by his total number of innings pitched, the result is the pitching ERA. Pitchers with the best pitch-to-inning ratio in the game often throw fewer than 15 pitches every inning.

## What does 0.1 inning mean in baseball stats?

During the time period in which the player is the pitcher of record, pitchers IP (also known as “innings pitched”) stats are recorded as the number of outs that the defense was able to create, stated in innings, during that time period. Three outs are equal to one inning in baseball. Any incomplete innings are represented by the sum of the number of complete innings plus the number of outs, which is denoted by a decimal.

- Six outs equals two innings
- Seven outs equals two and a half innings
- Eight outs equals two and a half innings
- Nine outs equals three innings.

Another convention is that a plus sign (+) appears next to the inning count if a pitcher starts an inning but is forced to leave before any outs are recorded.

That line may read “IP: 4+” if Smith pitching the first four innings, then faces three hitters in the fifth without recording an out before departing the game. Following is the amount of strikeouts earned by the pitchers in your scenario.

- Montgomery recorded 17 strikeouts, Green recorded 6 strikeouts, Ottavino recorded 1 strikeout, and Holder recorded 3 strikeouts for a total of 27 strikeouts (9 innings).

Despite the fact that the decimal notation that is routinely employed is not stated in the MLB rules, the practice of recording outs as fractions of an inning is described in great length in the document. It is stated in 9.02(c)(1) that the number of innings pitched is an official statistic that must be recorded, and it includes the following comment: 9.02(c) of the Rules of Civil Procedure (1) Comment: When calculating the number of innings pitched, the Official Scorer will consider each putout as one-third of an inning (13 innings total).

It is necessary for the Official Scorer to credit a starting pitcher with 5 innings if he or she is removed from the game with no outs in the sixth inning.

If a relief pitcher retires two batters before being relieved, the Official Scorer will give that pitcher credit for two-thirds of an inning pitched thrown.

## Baseball statistics – BR Bullpen

Baseball statistics are extremely essential, probably more so than in any other sport. Because the game of baseball has a fairly ordered flow to it, it lends itself to easy record keeping and statistical analysis, which is advantageous. As a result, it is extremely simple to create comparisons between players’ on-field performances, and as a result, baseball statistics are given greater prominence than they are in most other sports.

## Development of statistics

Henry Chadwick established the tradition of maintaining records of the players’ accomplishments in the 19th century, and it has continued ever since. Based on his cricketing expertise, Chadwick established the precursors of modern-day statistics such as batting average, runs scored, and runs allowed, among other things. The statistical world of baseball has traditionally been dominated by statistics such as hitters’ batting average (the number of hits divided by the number of at bats) and pitchers’ earned run average (roughly the number of runs given up by a pitcher per nine innings).

These statistics are intended to provide a more accurate representation of a player’s overall performance and contribution to his team from year to year.

In 1969, MacMillan Publishing published the firstBaseball Encyclopedia, which was the first publication to use a computer to gather statistics for the sport.

Interestingly, this research resulted in the identification of a number of players who did not appear in the official record books. In the case of Lou Proctor, for example, some of these “phantom ballplayers” were removed from the record books.

## Use of statistics

Player statistics are studied by general managers and baseball scouts in order to make conclusions about the skills of individual players. Managers, catchers, and pitchers research the statistics of opposing teams’ batters in order to determine the best way to pitch to them and place the players on the field in order to win the game. Managers and hitters research opposing pitchers in order to find out how to hit them the most effectively. Management makes personnel choices during games, such as who to start in the lineup and which relief pitcher to bring in, on the basis of statistical data collected throughout the game.

- The most frequently mentioned batting statistics are batting average, runs batted in, and home runs.
- For pitchers, wins, earned run average, and strikeouts are the classic statistics that are most frequently referenced.
- Some sabermetric data have made their way into the mainstream of baseball.
- It is calculated by multiplying the hitter’s base percentage (the number of times he or she reached base—by any means—divided by the total number of plate appearances) by the hitter’s slugging percentage (total basesdivided by at bats).
- The batting average of a pitcher is also significant in measuring his or her degree of success.
- A pitcher’s statistics may be broken down into several categories, the most important of which are K/9IP (strikeouts per nine innings), K/BB (strikeouts per walk), HR/9, WHIP (walks plus hits per inning thrown), and OOPS (opponent on-base plus slugging).
- In the case of pitchers, these statistics, such as the Defense-Independent ERA (dERA), make an attempt to evaluate a pitcher on the basis of events that are completely influenced by the pitcher’s performance and not by the strength of the defensive players behind him or her.
- An experienced manager may be more inclined to give a given batter more opportunities to face left-handed pitchers because of the hitter’s ability to hit left-handed pitchers.

Depending on the pitcher (or vice versa), other batters may have a track record of success against that pitcher, and the manager can utilize this knowledge to construct a beneficial matchup.

## Commonly used statistics

The majority of these terms are also applicable to softball. Several commonly used statistics, as well as their abbreviations, are explained in this section. In order to provide a quick reference, the explanations below do not fully or completely define the statistic; for a more thorough definition, please refer to the corresponding article for each statistic.

### Batting statistics

- A single hit that allows the batter to safely reach first base without the assistance of a fielding mistake is designated as 1B. 2B -Double-hits in which the hitter successfully advances to second base without the assistance of a fielding mistake
- 3B -Triple-hits in which the hitter successfully advances to third base without the assistance of a fielding error
- The term “at bat” refers to a batting appearance, which does not include bases-on-balls, balls hit by pitches, sacrifices, interference, or obstruction. At bats per home run (AB/HR) is the sum of at bats divided by the number of home runs. BA – Batting average (often abbreviated AVG) – the number of hits divided by the number of at bats The term “base on balls” refers to a situation in which a batter receives four balls and advances to first base. Walking to strikeout ratio (BB/K) is the number of base on balls divided by the number of outs in a game. Extra base hits (doubles, triples, and home runs) are referred to as XBH. FC (Fielder’s Choice) refers to situations when a runner reaches base after a fielder has decided to try to force an out on another runner. Number of ground balls out divided by the number of fly ball outs is known as AO/GO (Ground Ball Fly Ball Ratio). Number of ground balls that were hit and turned into double plays (also known as GDP or GiDP)
- When a home run is hit with the bases loaded, four runs are scored and four RBIs are recorded to the batter, this is known as a Grand Slam. Batted fair ball with no errors by the defense resulted in a hit, which allowed the batter to advance to second base. HBP (hit by pitch) refers to instances in which a pitch is touched and the batter is given first base as a consequence. Home runs are defined as hits on which the hitter successfully touches all four bases without the benefit of a defensive mistake. IBB stands for “intentional base on balls.” A base on balls (see BB above) is a base on balls that is intentionally thrown by the pitcher. IW (intentional walk) is another term for this activity. Number of times a strike three is taken or swung at and missed or a bunted foul is committed is denoted by the letter K. LOB (Left on Base) refers to the number of runners who are not out and have not scored at the end of an inning. OBP (On Base Percentage) is calculated by dividing the number of times a player has reached base (H + BB + HBP) by the total number of at bats plus walks plus hit by pitch plus sacrifice flies (AB + BB + HBP + SF). On-base plus slugging (OPS) is the sum of the on-base percentage and the slugging average. PA -Plate appearance – is the total number of completed batting appearances in a season. It is possible to assess how many runs a player has contributed to his team using the RC (Runs generated) statistic. In baseball, the term “run batted in” refers to the number of runners who have scored as the result of a hitter’s action, with the exception of when the batter grounds into a double play or reaches on an error. Sacrifice fly (SF) – the number of fly ball outs that allow another runner to advance on the basepaths or score a run
- Number of sacrifice bunts that have been made to allow another runner to advance on the basepaths or score
- SH -Sacrifice hit – SLG (slugging average) is the sum of all bases divided by the number of at-bats. To calculate total average, divide total bases plus walks plus steals by the number of plate appearances plus the number of times a player is caught stealing. T – Total bases: one for each single, two for each double, three for each triple, and four for each home run
- TB = Total bases
- TOB (Times on Base) refers to the number of times a player has reached base as a consequence of hits, walks, or being hit by a pitch.

### Baserunning statistics

- If someone is caught stealing, they are tagged out for a certain amount of time. Number of bases advanced other than through batted balls, walks, or hits by pitch
- SB -Stolen base R – Runscored – times when the player returned to home base legally and safely
- R – Runscored – times when the player returned to home base illegally and safely
- R – Runsscored – times when the player returned to home base illegally and safely
- R – Run

### Pitching statistics

- BABIP (Batting Average on Balls in Play) is a batting average against a pitcher on batted balls that end a plate appearance, excluding home runs, that is calculated after a plate appearance. BB is an abbreviation for “base on balls” (also called a “walk”) times throwing four balls, allowing the batter-runner to make it to first base on four different occasions In baseball, BB/9 is defined as the number of base on balls multiplied by nine and divided by the number of innings pitched (bases on balls for every nine innings pitched). BF – total batters faced – the total number of plate appearances made by the opponent In baseball, BK stands for the number of times a pitcher executes an unlawful throwing motion or other illegal activity while in contact with the pitching rubber, resulting in baserunners moving forward. Number of times a player has entered the game in a save position and then been charged with a run that ties the game
- BS -Blown save- CERA is an acronym that stands for Component In baseball, the term “earned run average” (ERA) refers to an estimate of a pitcher’s ERA based on the separate components of his statistical line (Ks, H, 2B, 3B, HR, BB, HBP)
- CG -Complete game – the number of games in which a player was the lone pitcher for his side
- A player’s CG -Complete game – DICE (Defense-Independent Component) is an acronym that stands for Defense-Independent Component. the estimated earned run average (ERA) of a pitcher based on the components of his statistical line that are not reliant on defense (K, HR, BB, HBP)
- In baseball, earned runs are the number of runs that are not scored as a consequence of mistakes or passed balls. ERA (earned run average) is calculated as follows: earned runs multiplied by the number of innings in a game (typically nine) divided by the number of innings pitched
- G -Games thrown (also known as’Appearances ‘) – the number of times a pitcher throws a pitch in a season. The number of games pitched in which the player was the last pitcher for his club is denoted by the letter GF (Games completed). Ground ball to fly ball ratio (G/F) is the number of ground balls permitted divided by the number of fly balls allowed. A player’s number of games pitched when he was the first pitcher for his team is denoted by the letter GS. H/9 -Hits per nine innings – Hits allowed multiplied by nine divided by the number of innings pitched (also known as H/9IP -Hits allowed per nine innings pitched)
- H/9IP -Hits allowed per nine innings pitched H -Hits Allowed – total number of hits permitted
- HB -Hit batsman – refers to a hitter who has been hit by a pitch, allowing the runner to reach first base. HLD (or H) -Hold- is the number of games in which a save situation has been entered, where the save situation has been abandoned, where at least one out has been recorded, and where the lead has not been relinquished
- HR -Home runs permitted – total number of home runs permitted It is permissible to use intentional base on balls (IBB). It stands for inherited runners, which is the amount of runners on base when the pitcher comes into the game. IRA (Inherited Runs Allowed) is the maximum number of inherited runners that can score. Innings pitched is the product of the number of outs recorded while pitching multiplied by three. Innings pitched per game (IP/GS) is the average number of innings pitched each game. K – Strikeout – the number of hitters that were hit with a third strike
- AKA K/9 (Strikeouts per nine innings) is calculated by multiplying the number of strikeouts by nine and dividing the number of innings pitched (Strikeouts per nine innings pitched). A ratio of strikeouts to walks is calculated by dividing the number of strikeouts by the number of base on balls. Winning percentage of games in which pitcher was pitching when the opposition side gained an early lead, never relinquished control of the lead, and went on to win
- Opponents batting average (OBA) is calculated by dividing the number of hits allowed by the number of at-bats faced. PITCH COUNT – Number of pitches thrown (Pitch Count)
- RA (Run Average) is the product of the number of runs allowed multiplied by nine and divided by the number of innings pitched. Running against the average is a sabermetric statistic that may be used to forecast victory %. SO – Shutout – the amount of complete games thrown without allowing a single run
- A pitcher’s save is the number of games in which a pitcher enters a game with a lead held by the pitcher’s team and exits that game with no loss of the lead, is not the winning pitcher, and either (a) the lead was three runs or less when the pitcher entered the game
- (b) the potential tying run was on base or at bat
- Or (c) the pitcher pitched three or more innings. In games when a pitcher was pitching while his team gained the lead and went on to win (also known as winning percentage), W represents the number of games won. When a pitch is thrown too high, too low, or too wide of home plate for the catcher to field, a wild pitch charge is applied, enabling one or more runners to advance or score.

### Fielding statistics

- It is possible to record the number of outs on a play in which a fielder touches the ball, save if such touching is for a putout, as a “Assist.” One for each double play in which the fielder recorded a putout or an assist, and one for each double play in which the fielder recorded an assist
- DP -Double plays Number of times a fielder fails to make a play that he should have made with reasonable effort, and the offense gains as a result of this failure
- To calculate fielding percentage, divide the total number of plays (chances less mistakes) by the total number of opportunities. INN -Innnings – the number of innings that a player spends in a specific position on the field When the ball is dropped and one or more runners advance, the catcher is charged with a passed ball (also known as a passed ball charge). Number of times a fielder tags, forces, or appeals a runner and the runner is subsequently thrown out
- PO – Putout Ranging factor (*9) divided by the number of innings played. When determining how much field a player can cover, this is taken into consideration. Stolen bases (also known as stolen bases) refer to the number of times a runner advances on a pitch without being caught by the catcher. TC stands for total chances, which includes assists, putouts, and mistakes. Each triple play during which the fielder recorded a putout or an assist is denoted by the letters TP (triple play).

### General statistics

- G -Games played – the total number of games in which the player participated in full or in part
