Batting Statistics

Batting Average (BA or AVG) = (Hits) / (At Bats)

Slugging Percentage (SLG) = (Total Bases) / (At Bats)

On Base Percentage (OBP) = (Hits + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice)

At Bats (AB) = (Plate Appearances) – (BB + HBP + Sacrifice + Catcher’s Interference)

Games (G) : The number of games the player played in.

Hits (H) = (Single(s) + Double(s) + Triple(s) + Home Run(s))

Total Bases (TB) = Sum of bases recorded on balls hit in play by the player. Single = 1; Double = 2; Triple = 3; Home Run = 4.

Runs (R) : The number of times the player scored a run.

Runs Batted In (RBI) : The total number of Runs to score as a direct result of the hitter’s plate appearance. A walk with the bases loaded still gives an RBI to the hitter that drew the walk. A judgement is made by the official scorekeeper when an error is involved on the play.

Sacrifice (SH or SF) : The player opts to intentionally give themselves up as an out in order to advance other runners on base. A Sacrifice Hit (SH) often involves the batter squaring around to bunt while a Sacrifice Fly (SF) must involve a player scoring as a result of their flyball. The batter is not given an AB if the base runners successfully advance.

Hit By Pitch (HBP) : The number of times a batter is struck by the pitch and rewarded first base. No AB is recorded in the end result of a HBP.

Walks (BB) : Commonly referred to as Base on Balls, a Walk is when the batter watched 4 balls and is then rewarded first base. No AB is recorded in the end result of a BB.

Intentional Walks (IBB) : Often signaled by the catcher standing up from his stance with his arm straight out towards the opposite batter’s box of that in which the current batter is standing. After 4 intentional balls are thrown the batter is rewarded first base. No AB is recorded in the end result of an IBB.

Strikeout (SO or K) : When the batter accumulates 3 strikes during the course of his AB he is determined out.

Stolen Base (SB) : The number of times that a player has advanced another base while the pitcher has the ball or has pitched the ball. There is such thing as Defensive Indifference that occurs typically late in blow-out games when the team chooses to allow the runner(s) to advance. No Stolen Base is recorded under these circumstances.

Caught Stealing (CS) : The number of times in which a player is either picked off by the pitcher or thrown out by the catcher without the ball being put in play by the batter.

Grounded into Double Plays (GDP) : The number of times the batter has directly batted a ball that resulted in at least 2 outs for the defense. No RBI(s) is recorded on this type of play.

Stolen Base Percentage (SB%) = (Stolen Bases) / (Stolen Base Attempts)

Plate Appearances (PA) : The sum of all possible outcomes as batter. Basically (Baseball) the number of time the player leaves their time in the box without being replaced by another player.

Runs Created (RC) = ((Hits + Walks) X Total Bases) / (At Bats + Walks)
