AB – At Bat  | an at-bat comes when a batter reaches base via a fielder’s choice, hit or an error (not including catcher’s interference) or when a batter is put out on a non-sacrifice.

R – Run  | a player is awarded a run if he crosses the plate to score his team a run.

H – Hit  | occurs when a batter strikes the baseball into fair territory and reaches base without doing so via an error or a fielder’s choice.

2B – Double  | a batter is credited with a double when he hits the ball into play and reaches second base without the help of an intervening error or attempt to put out another baserunner.

3B – Triple  | a triple occurs when a batter hits the ball into play and reaches third base without the help of an intervening error or attempt to put out another baserunner.

HR – Home Run  | occurs when a batter hits a fair ball and scores on the play without being put out or without the benefit of an error.

RBI – Run Batted In  | a batter is credited with an RBI in most cases where the result of his plate appearance is a run being scored. There are a few exceptions, however. A player does not receive an RBI when the run scores as a result of an error or ground into double play.

TB – Total Bases  | refer to the number of bases gained by a batter through his hits. A batter records one total base for a single, two total bases for a double, three total bases for a triple and four total bases for a home run.

AVG – Batting Average  | batting average is determined by dividing a player’s hits by his total at-bats for a number between zero (shown as .000) and one (1.000).

SLG – Slugging Percentage  | represents the total number of bases a player records per at-bat. The formula for slugging percentage is: (1B + 2Bx2 + 3Bx3 + HRx4)/AB.

OBP – On Base Percentage  | refers to how frequently a batter reaches base per plate appearance. Times on base include hits, walks and hit-by-pitches, but do not include errors, times reached on a fielder’s choice or a dropped third strike. 

OPS – On Base Plus Slugging Percentage  | adds on-base percentage and slugging percentage to get one number that unites the two. It’s meant to combine how well a hitter can reach base, with how well he can hit for average and for power.

BB – Base on Balls  | occurs when a pitcher throws four pitches out of the strike zone, none of which are swung at by the hitter. 

HBP – Hit by Pitch  | occurs when a batter is struck by a pitched ball without swinging at it. He is awarded first base as a result. Strikes supersede hit-by-pitches, meaning if the umpire rules that the pitch was in the strike zone or that the batter swung, the HBP is nullified.

SO – Strike Out  | represents the number of times a batter records an out by striking out, both looking and swinging.

GDP – Ground into Double Play  | occurs when a player hits a ground ball that results in multiple outs on the bases.
