Slugging percentage – Wikipedia
In baseball statistics, slugging percentage (SLG) is a measure of a batter’s ability to generate runs with his bat. It is calculated as total bases divided by the number of at bats for a given player using the following formula, where ABis the number of at bats for a given player and 1B, 2B, 3B, and HRare the number of singles, doubles, triples, and home runs, respectively: 1B, 2B, 3B, and HRare the number of singles, doubles, triples, and home runs In contrast to batting average, slugging % provides greater credit to extra-base hits, like as doubles and home runs, as compared to singles in the same game.
This formula does not include plate appearances that result in walks, hit-by-pitches,interference, catcher’s sacrifice bunts, or flies, because such an appearance is not considered to be anat bat in this case (these are not factored into batting average either).
In mathematics, it is a scale of measurement whose calculated value ranges from 0 to 4.
A double is worth twice as much as a single, a triple is worth three times as much as a home run, and a home run is worth four times as much as a single.
In order to avoid confusion, it’s sometimes referred to as “slugging average” or “slugging” instead.
If the slugging percentage is.589, it would be said as “five eighty nine,” and it would be spoken as “eleven twenty seven” if it were 1.127.
Facts about slugging percentage
A hitter’s slugging percentage is used for a variety of purposes other than determining his or her output. It may be used to evaluate pitchers in a variety of situations. It is not as prevalent as slugging-percentage against, but it is a measure of effectiveness. In 2019, the mean average SLG among all clubs in Major League Baseball was.435, according to Baseball Reference. The greatest slugging % has a numerical value of 4.000, which is the highest possible. However, no player in the history of the Major League Baseball has ever retired with a slugging percentage greater than 4.000.
Eric Cammack (2000 Mets), Scott Munninghoff (1980 Phillies), Eduardo Rodrguez (1973 Brewers), and Charlie Lindstrom are among the players on this list (1958 White Sox).
Take, for example, Babe Ruth, who made his major league debut in 1920 with the New York Yankees. After 458 at-bats, Ruth collected 172 hits, which included 73 singles, 36 doubles, 9 triples, and 54 home runs, for a grand total of 388 bases. Ruth had 73 singles, 36 doubles, 9 triples, and 54 home runs, for a grand total of 388 bases. His slugging percentage for the season is calculated by dividing his total number of bases (388) by his total number of at bats (458), which equals.847. This also established a new mark for Ruth, which held until 2001, when Barry Bonds amassed 411 bases in 476 at-bats, increasing his slugging percentage to.863, which has remained unsurpassed ever since.
It wasn’t until decades after it was first used that baseball analysts realized that it could be combined with on-base percentage (OBP) to provide a very accurate measure of the overall offensive production of a player (in fact, the combination of OBP and SLG was originally referred to as “production” by baseball writer and statisticianBill James). Branch Rickey devised a precursor meter in 1954, which is now known as the Branch Rickey metric. For example, Rickey claimed in the Lifemagazine that combining OBP with what he termed “extra base power” (EBP) would provide a more accurate estimate of player success than traditionalTriple Crown statistics.
They were among the first to combine the two modern-day statistics, multiplying them together to generate what is now known as “SLOB” (Slugging On-Base).
The next year (and probably independently), Bill Jamesapplied similar idea to hisruns createdformula, basically multiplying SLOB at bats to develop the following formula: Pete Palmer and John Thorn invented on-base plus slugging (OPS) in 1984, which is a simple combination of the two variables and is likely the most often used method of combining slugging and on-base percentage: on-base plus slugging (OBS).
In recent years, OPS has been increasingly popular as a shorthand method of evaluation for contributions as abatter, owing to its simplicity in calculation.
The theoretical maximum for “on base” is 1.000 points, but the theoretical maximum for “slugging” is 4.000 points.

Perfect slugging percentage
There is a numerical limit of 4.000 slugging percentages that can be achieved.
A significant number of Big League Baseball players (117 as of the conclusion of the 2016 season) have achieved a 4.000 career slugging percentage in their first major league at bat by homering in their first major league at bat.

What Is Slugging Percentage in Baseball? The Ultimate Guide
In baseball, huge hits are responsible for a large number of the game’s most thrilling plays. When a hitter hits a double into the corner of the infield, a triple into the alley, or a home run over the wall, it is called a double. Slugging % is a famous statistic that stresses the importance of swinging for the fences, and it is indicative of the sorts of plays that get spectators out of their seats and on their feet. So, what is the slugging % in this case? Extra-base hits, such as doubles, triples, and home runs, are calculated using the slugging percentage statistic, which indicates how successful a batter is at hitting these types of hits.
The statistic is determined by taking the total number of bases and dividing it by the number of at bats.
Let’s go a little more into the statistic:
What Is Slugging Percentage in Baseball?
The purpose of slugging % is to attribute a figure to a hitter’s ability to drive the ball and rack up extra-base hits, and this is accomplished via the use of advanced statistics. Despite the fact that the statistic is known as “slugging percentage,” the term is a little misleading because it is really a ratio, or what is known as a “rate stat,” rather than a genuine percentage. A batter’s slugging percentage (often abbreviated as SLUG or SLG, or simply referred to as “slugging”) is calculated by dividing the total number of bases or the total number of bases earned in all of his hits by the total number of official at bats.
It comes down to determining the average number of bases that a batter would gain for every official at bat, which means that both the ability to collect extra-base hits and the ability to do so on a consistent basis are important factors in achieving a high slugging percentage in the game of baseball.
Now we’ll get into how you go about determining what that number is.
How Do You Calculate Slugging Percentage in Baseball?
bmcent1 courtesy of Canva.com Two pieces of information are required in order to compute an individual’s slugging percentage: the total number of at bats the player has had and the total number of bases he has amassed. The slugging percentage formula is rather straightforward, and it is derived by dividing the total number of bases scored by the total number of at bats taken. Total bases are calculated by taking a batter’s total number of hits and adding one additional base for each double, two more bases for each triple, and three additional bases for each home run.
- One important point to keep in mind while calculating slugging % is that it only considers legitimate at bats and not unauthorized at bats.
- Bases on balls (walks), hit-by-pitch, sacrifice bunts, and sacrifice flies are all deleted from the at bat ledger for the sake of keeping track of the number of at bats.
- For practice, let’s look at how to compute a hitter’s slugging percentage: Consider the following scenario: a hitter has 235 plate appearances, but has only walked 20 times and has been hit by five pitches.
- Due to the omission of the last four columns (20+5+5+5), the number of at bats for the batter will be 200 instead of 200+5.
- To calculate total bases, start with the 60 hits and then add 10 for doubles (one base for each), another 10 for triples (two bases apiece), and 30 for home runs to get the total (three bases each).
- Finally, if you split 110 total bases by 200 at bats, you get a slugging percentage of 0.55, which is a good result.
- The question is whether that is a reasonable number or not.
What Is a Good Slugging Percentage in Baseball?
The fact that slugging % is a rate statistic means that it is subject to up-and-down variations in Major League Baseball as the league’s conditions change. It is possible that these changes will take the form of a changed composition of the actual baseball, regulation changes, new ballparks (with different dimensions), altering trends in pitcher use, or even weather that is poorer than typical throughout the season. Despite this, there is a very well-defined threshold for what constitutes a “good” slugging percentage.
- Similarly, heading towards the extremes, a slugging percentage of.350 is considered bad, while a slugging percentage of.650 is considered excellent.
- On the opposite end of the scale, 119 hitters have produced a slugging percentage below.350 since 2005, which is the most recent period available.
- For example, eight players have had a slugging average greater than.650 in a season since 2005.
- The opposite is true for the 119 guys who batted below.350 in a season; just one of them, Luis Castillo, managed to bat above.300 in 2009, batting.302 as a result of his only 16 extra-base hits for the whole season.
- Another interesting fact about that ranking is that only 15 of the 119 players hit 10 or more home runs that season, with no one reaching more than sixteen.
The batting average of none of those players exceeded.252, a very terrible mark that demonstrates how hitting for a bit more power at the expense of your overall average may have negative consequences for your overall performance in baseball.
History of Slugging Percentage
Because slugging % is a rate statistic, it is subject to up-and-down variations in Major League Baseball as the league’s circumstances change. It is possible that these changes will take the form of a changed composition of the actual baseball, regulation changes, new ballparks (with different dimensions), shifting trends in pitcher usage, or even weather that is poorer than usual throughout the season. Although this is the case, there is a more or less established baseline for a “good” slugging percentage that may be used to measure performance.
- The same can be said for a.350 strikeout to walk ratio, which is mediocre, and a.650 strikeout to walk ratio, which is exceptional.
- The other end of the spectrum is shown by the 119 hitters who have produced a slugging percentage of less than.350 since 2005.
- A season slugging average of.650 or above has been achieved by eight players since 2005.
- One of the 119 players with a batting average below.350 in a season, Luis Castillo (batting.302), was the only one to hit over.300 in 2009, owing to the fact that he had just 16 extra-base hits during the season.
- This is because four singles equal the same number of total bases as a home run.
- The batting average of none of those players exceeded.252, a very terrible mark that demonstrates how hitting for a bit more power at the expense of your overall stats may be harmful to your overall performance.
Career Slugging Percentage Leaders
In terms of career slugging percentage, the following are the top five:
- Joe DiMaggio had a career slugging percentage of.5821, while Babe Ruth had one of the best in baseball history at.6897. Ted Williams had a career slugging percentage of.6338, while Lou Gehrig had one of the best at.6324. Jimmie Foxx has one of the best in baseball history at.6093, while Barry Bonds has one of the best at 6069. Hank Greenberg has one of the best in baseball history at
What Is On Base Percentage?
When a hitter makes it to base more than once per plate appearance, this is known as the on base percentage (OBP). It is possible to get on base % by counting walks, hits, and hit-by-pitch, but it does not include errors, fielder’s choice, dropped strike three, fielder’s obstruction, catcher’s interference, and sacrifice bunts, among other things.
Odds and Ends About Slugging Percentage
- Barry Bonds established the record for the greatest single-season slugging percentage in 2001 with an.863 mark. Bonds amassed 411 total bases in only 476 at-bats that season, including a Major League-leading 73 home runs, which set a new record for the most in a single season. Additionally, Bonds’ batting average for the season was.328, shattering Babe Ruth’s 81-year-old single-season record of.847, which had been held since 1920. Bonds and Ruth are the only men to have achieved the top six slugging percentages in a season, with each of them claiming three of those illustrious campaigns. They are also the only players in Major League Baseball history to have a slugging percentage greater than.800 in a single season, with each of them accomplishing this feat twice
- The highest single-season slugging percentage for a team in history is.495, achieved by the 2019 Houston Astros, who hit a combined total of 288 home runs. Additionally, the 2019 Minnesota Twins and 2019 New York Yankees both posted.494 and.490 batting averages, which were the second and fourth greatest records in Major League Baseball history, respectively. Because they had the greatest batting average of the three teams, the Astros had the highest batting average, hitting.274
- While the Red Sox had the lowest batting average, hitting.238.
- Barry Bonds established the record for the greatest single-season slugging percentage in 2001 with an.863 mark. This season, Bonds collected 411 total bases in just 476 at-bats, including a Major League-leading 73 home runs, setting a new record for the most in a season in the majors. It was also the first time in 81 years that a single-season batting average of.328 was broken, breaking Babe Ruth’s record of.847 from 1920. In a season, Bonds and Ruth both have three of the top six slugging percentage marks in baseball history, with each player having a slugging percentage of 1.000 or higher. Each of them has also recorded a slugging percentage greater than.800 in a single season, with each of them having done so twice
- The highest single-season slugging percentage for a team in MLB history is.495, which was achieved by the 2019 Houston Astros, who hit a combined total of 288 home runs in the regular season. Aside from that, the Minnesota Twins and the New York Yankees both finished with marks of.494 and.490, respectively, which were the second and fourth best marks in MLB history. When it came to batting average, the Astros had the best of the three teams at.274
- The Mariners had the second best at.266
- And the Royals had a batting average of.266.
What is Slugging Percentage (SLG) in Baseball?
We rely on the generosity of our readers. If you make a purchase after clicking on one of our affiliate links, we may receive a commission. In addition, we get commissions from eligible Amazon sales because we are an Amazon affiliate. It is becoming increasingly apparent to baseball fans across the world that the game they have learned to love over the years is changing significantly. A game that was formerly dictated by what transpired on the field is slowly but steadily shifting to become increasingly reliant on statistical analysis and analysis of data.
A hitter’s output was once measured by his batting average and home runs, and pitchers were assessed by their wins and earned run average.
In today’s game, knowing baseball statistics has never been more important, and understanding what those numbers imply is essential to comprehending the game.
The slugging percentage of a batter is a statistic that is used to assess the power output of a hitter.
It is computed by adding up all of the batter’s total bases and dividing that total by the number of at-bats the hitter has had. In a situation when all hits are equal, slugging percentage lends greater weight to extra base hits than batting average.
An Example on How to Caculate Slugging Percentage (SLG)
Here is an example using two fictitious players, designated as Player A and Player B.
For the sake of simplicity, we will assume that both players have precisely 100 at-bats (AB). In this example, Player A has more hits (H) than Player B, resulting in a better batting average (BA) for Player A. If you want to know what their slugging percentage is, you may apply the following formula: SLG is equal to 1B(1) + 2B(2) + 3B(3) + HR(4) / AB. Because the numerator in this formula represents the total number of bases, all singles are multiplied by one in the denominator. Doubles are multiplied by two, triples are multiplied by three, and home runs are multiplied by a factor of four.
Because he has more hits than Player B, Player A has a better batting average than Player B. It’s important to remember that batting average treats all hits equally. Player B, on the other hand, has a better slugging percentage than Player A, owing to the fact that he has more extra base hits, particularly home homers. This does not necessarily imply that Player B is a better hitter than Player A, but it does imply that he has a higher power productivity than the former. Player A may receive more hits, but Player B has a better chance of doing more damage at the plate.
The History of Slugging Percentage
The slugging % has been around since the early 1950s, however it took some time for the statistic to achieve prominence in the sport of baseball. The former Los Angeles Dodgers executive Branch Rickey is not only credited with helping to break down the color barrier in Major League Baseball by signing Jackie Robinson, but he is also credited with developing the formula that is now used to calculate a hitter’s slugging percentage. Rickey, on the other hand, cannot be attributed with the discovery of this statistic on his own.
Roth and Rickey came up with the term “Extra Base Power” (EBP) to describe a more accurate manner of evaluating a hitter’s output at the time.
This statistic would subsequently be known as slugging percentage, and it achieved widespread recognition as a result of Bill James’ SABRmetrics, in which he utilized it to build his own calculation known as “Runs Created,” which became popular (explained later).
How Slugging Percentage is Used to Make Decisions
A club’s slugging percentage may be utilized in a variety of ways to assist coaches, scouts, and executives in making decisions — whether they be personnel or in-game decisions — that will help them put together the finest baseball team possible on the field. In the video included in the “Example” section above, the coach discusses how slugging percentage may be utilized to determine how to arrange a batting lineup. The players with the greatest slugging % should be assigned to the positions in the lineup where the coach wants his most potent power threats to be found, and vice versa.
A more sophisticated application of slugging percentage is the calculation of a player’s on-base percentage (OPS) (on-base plus slugging percentage).
Let’s go back to Players A and B and determine their overall point differential.
Player A’s OBP and SLG (.408 +.420) were simply combined together, whereas Player B’s OBP and SLG (.347 +.540) were added together to obtain their OPS. As you can see, Player B is still somewhat more important than Player A in terms of getting on base and displaying power when comparing their on-base percentages and on-base percentages. (For more information on on-base percentage, see the article “What is a Good On-Base Percentage (OBP) in Baseball” for further information.) It is possible for professional sports recruiters and executives to utilize this statistic to assess a player’s prospective effect on their respective teams.
Another even more complex application of slugging percentage is found in the Bill James’ Runs Created method, which is frequently employed by professional teams when making personnel choices (referenced earlier).
In this case, the formula is as follows: /= New Runs Have Been Created Let’s also compute the Runs Created for Players A and B for the sake of completeness.
Player A:/= RC/= RC/= 17.16 Player B:/= RC/= RC/= 17.16 Player B:/= RC/= RC/= 14.61; Player A:/= RC/= RC/= 14.61; Player C:/= RC/= 14.61; This demonstrates how much more complicated analytics may be, as well as how organizations who are led by SABRmetrics are more inclined to prioritize Player A above Player B. The slugging % has established itself as a metric that is more useful than the batting average for those in charge of making in-game and personnel decisions, regardless of how it is calculated.
Slugging Percentage Records
Dennis Sylvester Hurd captured this image.
The following are the top five lifetime slugging percentage leaders in the history of Major League Baseball:
- Babe Ruth had a.689 batting average
- Ted Williams had a.633 batting average
- Lou Gehrig had a.632 batting average
- Mule Suttles had a.617 batting average
- Turkey Stearnes had a.616 batting average.
Baseball players Babe Ruth (689), Ted Williams (633), Lou Gehrig (632), Mule Suttles (617), Turkey Stearnes (616), Babe Ruth (689), Ted Williams (633), Babe Ruth (632), Ted Williams (633), Babe Ruth (632), Ted Williams (633), Babe Ruth (632), Ted Williams (632), Babe Ruth (632), Ted Williams (632), Lou Gehrig (632), Babe Ruth (632)
- The following players had a.974 batting average: Josh Gibson (1937), Mule Suttles (1926), Charlie Smith ( 1929), Josh Gibson (1943), Barry Bonds (2001), and Mule Suttles (2001).
As can be seen from this list, several of these players achieved these achievements during years when slugging percentage was not even taken into consideration. Fortunately, baseball historians have gone back in time and given them the recognition they rightfully deserve. In the Major League Baseball (MLB), there have only been four seasons in the previous thirty years in which the league’s slugging percentage as a whole fell below.400. The slugging percentage for this season is currently.402, which is a decrease from the slugging percentage for the last complete Major League season, which was.435, which was in 2019.
This might be owing to the fact that pitchers have been more dominating in recent years.
Frequently Asked Questions
In baseball, the slugging percentage is intended to measure a hitter’s ability to generate power when the ball enters the field of play. Walking and hitting by pitches are important statistics to track, but they do not reveal a player’s power potential. This was the impetus for the creation of OPS.
Do professional scouts use slugging percentage in drafting players?
College players’ slugging percentage will very certainly be taken into consideration when determining whether or not they are worthy of being selected by the major leagues in the draft. It is possible that high school statistics will not be taken into consideration as much when picking high school athletes since they are less dependable.
Is it possible for a slugging percentage to be over 1.000?
Yes, it is feasible for a player to slug more than 1.000 in a single game. The majority of a player’s hits would have to be extra-base hits in order for this to be possible.
What is a perfect slugging percentage?
A perfect slugging percentage is equal to 4.000 percent. In order to achieve this, a player must never be struck out and must only hit home runs on the season. This is practically difficult to achieve during the course of a season’s worth of games. Also see: How to Clean a Baseball Cap with Cardboard Bills for more information.

Barry Bonds now owns the Major League Baseball record for the greatest slugging percentage in a season (.863). In baseball statistics, slugging percentage (sometimes known as slugging percentage or SLG) is a measure of a batter’s power. It is computed as the sum of all bases divided by the number of at bats. SLG = (s + 2d + 3t + 4hr) / (s + 2d + 3t + 4hr) SLG is calculated as (h + d + 2t + 3hr) / AB, where AB is the number of at-bats for a specific player and s, h, d, t, hr are the number of singles, hits, doubles, triples, and home runs for that player, respectively.
The phrase “slugging percentage” is a misnomer since it refers to a weighted average rather than a percentage.
It took 458 at-bats for him to get 172 hits, which consisted of 73 hits (one for each at-bat), 36 doubles, nine triples, and 54 home runs, for a total of 388 bases (73 for one, 36 for two, nine for three, and 54 for four).
Babe Ruth led the league in slugging average the following year, and those marks stood for 80 years until 2001, when Barry Bonds hit 411 total bases in 476 at-bats, raising his average to.863, a mark that has stood unbroken since.
Babe Ruth led the league in slugging average 13 times (1918-1931, with the exception of 1925), the most times that any batter or pitcher has done so in any major category.
Slugging average’s significance
Although it was initially used in baseball many years ago, the slugging percentage received new relevance when baseball analysts found that when paired with on-base percentage (OBP), it provided a highly accurate representation of a player’s total performance. Branch Rickey devised a precursor meter in 1954, which is now known as the Branch Rickey metric. Rickey proposed in Life Magazine that combining on-base percentage (OBP) with what he dubbed “extra base power” would provide a more accurate estimate of player performance than traditional Triple Crown data.
According to Allen Barra and George Ignatin, they were among the first to combine the two modern-day statistics, multiplying them together to generate what is now known as “SLOB” (Slugging On-Base), which stands for Slugging On-Base.
In 1984, Pete Palmer and John Thorn devised what is perhaps the most widely used method of combining slugging and on-base average: the on-base percentage system (OPS).
Despite being less precise than SLOB and Runs Created, OPS is relatively simple to compute and has emerged as the unofficial shorthand for player assessment in recent years, despite its lower accuracy.
The slugging percentage (abbreviated as SLG and sometimes known as the slugging average) is the number of total bases divided by the number of at bats in a game. It has the following formula: (+++)/At bats are distinct from plate appearances. (+++)/At Bats is a formula that is equivalent. This method is less straightforward, but it is frequently more handy because assingles are not always provided (although they could easily be deduced). The number of singles may be calculated using the following equation, because they are just hits that do not result in extra bases.
The SLG+ statistic, which is an adjusted slugging percentage that accounts for the stadium and league that the player played in, is another useful statistic. Aside from that, the number is “normalized,” such that the median is 100 and the scores that are greater than average are over 100. SLG+ is calculated using the formula SLG+ = 100*(SLG/lgSLG), where lgSLG is the league average for the year in question.
How to Calculate Slugging Percentage
Documentation Download Documentation Download Documentation While a home run counts the same as a single in terms of batting average, slugging percentage takes into consideration the actual number of bases that are scored. However, despite its name, this statistic is really an average rather than a percentage. A player who has a high slugging percentage is one who scores a high number of bases per opportunity at the plate.
- Read More About ItRead More About It The difference between batting average and slugging percentage is that the former takes into account the number of bases scored while the latter takes into account the number of hits. As opposed to its name, this statistic is really an average rather than a percentage. In addition to scoring more bases per opportunity at bat, a player with a high slugging percentage also hits more home runs.
- 1 Recognize the importance of slugging percentage. This statistic, which is also known as slugging average, SA, or SLG, represents a player’s average number of bases per bat. It is reasonable to assume that the typical outcome for a player with a (unrealistic) slugging percentage of 1 was a single.
- This only counts the amount of bases gained by hits, not the number of bases gained through walks or being hit by a pitch. It is more accurate to estimate offensive power if the bases are not taken into consideration because they are beyond the control of the hitter.
- 2 Determine the total number of singles. Singles are not included in the majority of player statistics, however it is possible to determine this from other statistics. First, combine all of the hits that aren’t singles together, such as home runs, triples, and doubles. To find the number of Singles, subtract your answer from the total number of Hits.
- For example, Willie McCovey’s career statistics include 521 home runs, 46 triples, and 353 doubles, for a total of 920 points. Calculate the number of singles by subtracting 920 from his total career hits (2211), which is 1291.
- s3 Determine the total number of bases. In order to get the total number of bases, add together (Singles) + (2 x Doubles) + (3 x Triples) + (4 x Home Runs) to obtain the total number of bases.
- William McCovey collected a total of 4219 bases, which is equivalent to (1291) + (2 x 353) + (3 x 46) + (4 x 521) = 1291 + 706+ 138+ 2084 = 4219 bases total.
- 4 Divide your answer by the number of at bats. The slugging percentage is calculated by dividing the total number of bases by the total number of at bats.
- Considering Willie McCovey had 8197 at bats during his career, his career slugging percentage is 4219 divided by 8197 = 0.5147. (rounded to 0.515). With a bit more than one base on every two at bats, he was able to put together an impressive stat line
- 1 Use a quicker approach to determine the total number of bases. The approach described above is the simplest to comprehend, but it necessitates the use of additional arithmetic to determine the number of singles. Here’s a method to bypass that step and instead determine the total number of bases by utilizing Hits: Total bases are calculated as follows: hits + doubles + (2 x triples) + (3 x home runs).
- All of the singles are taken care of by one base every hit, which is why it works. Due to the fact that this also gives one base for each double, you simply need to add one additional base for each double to get at the final result. Similarly, for triples and home runs, add two additional bases and three further bases respectively.
- 2Divide by the number of at bats. As previously stated, the slugging percentage is equal to the total bases divided by the total number of at bats. Advertisement
- Adding Slugging Percentage to On Base Percentage is a good way to start. The resulting statistic, On Base Plus Slugging (OPS), takes into consideration the most essential offensive statistics. Baseball statistics do not believe this to be an accurate measure of offensive power, but it is a fast and simple method to compare offensive power.
- OPS+ is a less widely used statistic that takes into account the league and the park where the player plays. The formula for calculating OPS+ changes every year, with 100 being the league average.
- 2 Adjust the slugging percentage to the appropriate league. This statistic was created just for the baseball encyclopediaTotal Baseball and is rarely seen anywhere else in baseball. If you want to compare players from various years, this is a more accurate method to use, although it may be difficult to find the information you need to compute it:
- Adjusted production (APRO) is calculated as follows: (On Base Percentage / League OBP) + (Slugging Average / League SA) – 1
- (On Base Percentage / League OBP) = (On Base Percentage / League OBP) + (Slugging Average / League SA) = (On Base Percentage / League OBP) + (Slugging Average / League SA) = (On Base Percentage / League SA) + It is the average of all players’ stats for the whole season that is used to calculate the League statistics. The statistics are occasionally adjusted to account for variances across parks, as well as other factors.

- This statistic, like many others in baseball, is frequently shown without a decimal point. An SLG of 300 indicates that the team is averaging 0.300 bases per at bat, not three hundred. At bats do not include all plate appearances
- Rather, they include just those in which the hitter attempts to advance to the next base. It makes no difference whether or not an individual gets a walk or makes a sacrifice play
- A player’s slugging percentage remains same.

About This Article
Summary of the articleXThe following formula can be used to compute slugging percentage: SP is calculated as total bases minus at bats, where total bases is the number of bases the player moved as a result of hits and at bats is the number of times the player was up to bat. To get the total number of bases, apply the following formula: total bases = hits + doubles + (2x triples) + home runs (3x home runs). Then, using the value you obtained, enter it into the original formula and solve for the player’s slugging % to determine his or her performance.

It is possible to utilize slugging percentage (SLG) to identify which player is superior when two or more players have the same or nearly the same batting average (batting average). It is possible to determine this proportion by using the formula below. a few terms that are useful Total bases equals the number of bases that have been covered. The number of official at bats equals the number of times a hitter takes the field. A home run equates to four bases. Three bases are equal to a triple.
- A single base is equal to one base.
- When the percentage is high, it indicates that the player has hit the ball further or better, which has resulted in him reaching more bases or hitting more home runs.
- The greater the number of outs, the lower the SLG.
- For the sake of computing this SLG, we typically round decimal responses to three decimal places.
A few real-life examples that will show you how to find the slugging percentage
As an illustration, consider the following player’s performance during a baseball game: 3 home runs, 5 triples, 12 doubles, 20 singles, and 40 strikeouts The slugging percentage of the player is what you want to know. 3 home runs = 3 x 4 = 12 bases on the board. 5 triples equals 5 3 = 1512 doubles equals 12 2 = 2420 singles equals 20 1 = 20 triples The total number of bases is 12 + 15 + 24 + 20 = 71. The total number of at bats is calculated by adding everything in bold above. Three, five, twelve, twenty, and forty at bats total 80.
Following the rounding process to three decimal places, we obtain 0.888.
1 home run = 1 4 = 4 bases on the board.
Total at bats = 1 + 6 + 14 + 25 + 30 = 76 total at bats SLG = (Total bases) / (Total bases) (Number of official at bats) SLG = (75/76)SLG = 0.98684 SLG = (75/76)SLG = 0.98684 Following the rounding to the third decimal point, we obtain 0.987
So what are OBP/SLG/OPS/wOBA anyway?
The seminalFor All The Dummiesfanpost and the wonderful comments on FIPandstatistical education in general prompted me to think I’d do my part by teaching some fundamental and advanced hitting statistics. Many of you will already be familiar with most of this, so I’ll simply start with the fundamentals that we all know and work my way up to what I believe to be the most important single hitting statistic. The dreaded batting average with all of its complications. It was common knowledge when we were growing up that a guy who hit.300 was considered to be an excellent hitter.
The difficulty is that batting average fails to account for two important factors.
There are other significant methods to get to base as well, such as walking routes.
A single is not worth as much as a double or a home run, for example.
As a result, two extra statistics may be used to fill in the gaps left by batting average.
It is computed by adding up the number of hits, walks, and strikeouts and dividing that total by the number of plate appearances (not just at bats).
When you add those two numbers together, you get On Base Plus Slugging Percentage(OPS), which is a useful but awkward single hitting statistic.
The most significant flaw is that it treats OBP and SLG as though they are equal when they are not.
Second, and perhaps more crucially, both OBP and SLG do not contribute equally to run scoring.
wOBA is the solution to the problem.
It is calculated using a linear weighting technique to estimate the run value of a plate appearance based on the various outcomes of a plate appearance.
Without getting into too much detail, wOBA is a complex calculation, so I delegated it to others.
What is the significance of this number?
David Cameron of Fangraphs expressed it this way: To put it another way, it indicates that the average wOBA will always be equal to the average OBP for any given year.
A typical league average falls between.335 and.335 points – it was.332 points last year – but offense was down across the game in 2008, and that trend could or might not continue in 2009.
At the moment, the park is not normalized.
Furthermore, it makes no attempt to equalize players who are in various positions.
They do, however, exist.
So, how does this relate to the Royals in this instance?
