# Baseball Stats Abbreviations – What Do They Mean?

Hey everyone and welcome back! Today, we will be going through some of the most common baseball stats abbreviations and their meanings.

The game of baseball is filled with tons of statistics. Some of the abbreviations used can be quite easy to understand, while others can be downright confusing.

I get a lot of questions about what this stat or that stat means, so I thought I would go over some of the most commonly used baseball stats abbreviations and some that may not be quite as common.

These abbreviations apply to softball as well. I hope this helps to clear up some confusion.

## Baseball Stats Abbreviations

Let’s get started with batting and then work our way through ðŸ™‚

### Batting Stats Abbreviations

**AB **= **At Bat** – An at bat is an official plate appearance that does not include a walk, being hit by a pitch, obstruction, sacrifice, or an interference call.

**HR = Home Run **– A home run is achieved by a batter who hits a thrown pitch over the outfield fence, or hits the ball and successfully touches all three bases and home plate with no defensive errors (In the park home run).

**1B = Single** – A single is scored when a batter hits the ball and successfully reaches first base without a defensive error.

**2B = Double **– A double is scored when a batter hits the ball and successfully reaches second base without a defensive error.

**3B = Triple **– A triple is scored when a batter hits the ball and successfully reaches third base without a defensive error

**BB = Base on balls **– More commonly known as a “walk”, a base on balls is achieved by a batter who receives 4 pitches out of the strike zone during an at bat. A walk will be considered an “unofficial at bat”.

**IBB = Intentional base on balls **– Also known as an intentional walk (**IW**), an intentional base on balls is scored when a pitcher delivers 4 pitches out of the strike zone on purpose.

**HBP = Hit by pitch **– If a batter is hit by a pitch, they are automatically awarded first base. If the bases happen to be loaded at the time, the batter is also credited with a run batted in. This is also the case with a BB and an IBB.

**BA = Batting average **– A hitter’s batting average is calculated by taking the number of hits divided by the number of “official” at bats.

**OBP = On base percentage** – A players on base percentage is how many times they reach base safely via a hit, walk, or hit by pitch divided by number of at bats, plus walks, plus hit by pitch, plus sacrifice flies. (Hits+Walks+Hit by pitch) / (At Bats+Walks+Hit by pitch+Sacrifice Flies). This is my favorite stat for determining a batter’s true value.

**RBI = Runs batted in **– A batter is credited with a run batted in when a runner already on base scores due to their action during an at bat, except when they ground into a double play, or if a defensive error occurs. A batter is also awarded an RBI for theirself for a home run. If a batter hits a home run with the bases loaded, they would be credited with 4 RBI’S.

**SLG = Slugging average **– Also known as slugging percentage, SLG is the total number of bases achieved divided by the total number of at bats.

**OPS = On base plus slugging **– A batters OPS is their on base percentage plus their slugging average.

**XBH = Extra base hits **– Extra base hits are any hit by a batter where they reach second base, third base, or home safely, without a defensive error.

**TB = Total bases** – Total bases are the number of bases a batter reaches safely. 1 for a single, 2 for a double, 3 for a triple and 4 for a home run.

**LOB = Left on base** – LOB is the total number of runners left on base at the end of an inning.

**TA = Total average** – A batter’s total average is as follows – Total bases + steals + hit by pitch + walks, minus caught stealing, divided by at bats, minus hits, plus caught stealing, plus grounded into double plays.Â Here’s the mathematical equation (TB+SB+HBP+BB-CS)/(AB-H+CS+GIDP). Definitely one of the most confusing stats!

### Pitching Stats Abbreviations

**ERA = Earned run average **– A pitcher’s earned run average is the total earned runs given up, multiplied by 9 and divided by the total number of innings pitched.

**ER = Earned run **– Earned runs are the total number of runs allowed by a pitcher that were not the result of a defensive error or a passed ball by the catcher.

**SO = Strikeout **– Commonly noted as a **K**, the pitcher is credited with a strikeout when the batter receives 3 strikes during an at bat.

**BB = Base on balls** – A base on balls (walk), is awarded to the batter when a pitcher delivers 4 pitches out of the strike zone during an at bat.

**G = Games** – The total number of times a pitcher pitches during the season.

**GS = Games started** – The total number of games in which a pitcher was the first person to pitch for their team in a game.

**CG = Complete game** – A complete game is when a pitcher is the only player to pitch for their team during an entire game.

**W = Win** – A pitcher is awarded a win if they are pitching when their team had the lead after 5 completed innings and ultimately went on to win the game.

**L = Loss** – A pitcher is given a loss if they were pitching when the opposing team had and kept the lead, and went on to win that game.

**H = Hits allowed** – The total number of hits allowed by the pitcher.

**WHIP = Walks and hits per innings pitched** – The average number of hits and walks allowed by the pitcher per inning.

**WP = Wild pitch** – A pitcher is charged with a wild pitch when they throw a pitch so far out of the strike zone that the catcher is unable to field it, thereby allowing runners to advance at least one base or score a run. A wild pitch is not charged to the pitcher if there is no advancement by a runner, or there are no runners on base.

**SV = Save** – A save is awarded to a pitcher who enters the game with the lead and completes the game without giving up the lead. (1)The pitcher is not the winning pitcher or(2) the lead has to be 3 runs or less when they enter the game (3) The potential tying run is on base, at bat, or on deck.

Let’s take a quick commercial time out, do a little shopping and then move on to some fielding and base running stats. ðŸ™‚

### Fielding Stats Abbreviations

**A = Assist** – An assist is the number of outs recorded on a play where the player fielded the ball.

**E = Error** – A fielder is charged with an error if they fail to make a play that they should have been able to make using “common effort”.

**FP = Fielding percentage **– Fielding percentage is the total number of plays made, minus errors, divided by the total number of chances.

**INN = Innings** – The total number of innings that a player plays at one position.

### Base Running Stats Abbreviations

**R = Runs** – A base runner is credited with a run scored every time they reach home safely.

**SB = Stolen base** – A runner is credited with a stolen base when they advance at least one base while the defense has control of the ball.

**CS = Caught stealing** – A runner is considered caught stealing each time they are tagged out when trying to steal a base. (They didn’t make it to the next base before a defender tagged them out).

**SBA/ATT = Stolen base attempts **– Number of times a runner has tried to steal a base.

**SB% = Stolen base percentage** – Successfully stolen bases divided by the total number of attempted stolen bases.

What about SAC

Hi Kathy.

SAC is commonly used to denote that a batter has been credited with a sacrifice hit.

When a runner who is already on base is able to advance due to a hit ball, the batter is awarded with a “SAC fly” or “SAC bunt”.

If you are not sure what a sacrifice is – Check Out This Article
