In baseball, RBI stands for "runs batted in" and is a statistic that measures a players offensive production and contributions to their teams scoring. A player is credited with an RBI when they hit a batted ball in a way that allows a runner on base to advance to home plate and score a run. This can be earned by hitting a single, double, triple, or home run, as well as by being hit by a pitch with the bases loaded or by reaching base on an error or fielders choice with runners on base. A player can also earn an RBI when they make outs, provided the out results in a run or runs, except in the case of double plays.

Some examples of what counts as an RBI include:

• A safe hit that allows a runner to score
• A sacrifice fly or bunt that allows a runner to score
• A bases-loaded walk or hit by pitch that forces a runner to score
• A groundout or flyout that allows a runner to score

Some examples of what does not count as an RBI include:

• A run that scores as a result of an error
• A run that scores as a result of a double play

RBI is one of many statistics recorded in baseball to measure a players performance and contributions to their team. Other statistics include hits, doubles, triples, walks, strikeouts, and more.
