A run batted in (RBI), plural runs batted in (RBI or RBIs), is a statistic in baseball and softball that credits a batter for making a play that allows a run to be scored (except in certain situations such as when an error is made on the play). For example, if the batter bats a base hit, then another player on a higher base can head home to score a run, and the batter gets credited with batting in that run.
Before the 1920 Major League Baseball season, runs batted in were not an official baseball statistic. Nevertheless, the RBI statistic was tabulated—unofficially—from 1907 through 1919 by baseball writer Ernie Lanigan, according to the Society for American Baseball Research.
Common nicknames for an RBI include "ribby" (or "ribbie"), "rib", and "ribeye". The plural of RBI is generally "RBIs", although some commentators use "RBI" as both singular and plural, as it can also stand for "runs batted in".
A run batted in is a statistic credited to a batter whose action at bat causes one or more runs to score, as set forth in this Rule 9.04.
(a) The official scorer shall credit the batter with a run batted in for every run that scores
- (1) unaided by an error and as part of a play begun by the batter's safe hit (including the batter's home run), sacrifice bunt, sacrifice fly, infield out or fielder's choice, unless Rule 9.04(b) applies;
- (2) by reason of the batter becoming a runner with the bases full (because of a base on balls, an award of first base for being touched by a pitched ball or for interference or obstruction); or
- (3) when, before two are out, an error is made on a play on which a runner from third base ordinarily would score.
(b) The official scorer shall not credit a run batted in
- (1) when the batter grounds into a force double play or a reverse-force double play; or
- (2) when a fielder is charged with an error because the fielder muffs a throw at first base that would have completed a force double play.
(c) The official scorer's judgment must determine whether a run batted in shall be credited for a run that scores when a fielder holds the ball or throws to a wrong base. Ordinarily, if the runner keeps going, the official scorer should credit a run batted in; if the runner stops and takes off again when the runner notices the misplay, the official scorer should credit the run as scored on a fielder's choice.
From 1980 to 1988, the game-winning RBI was an additional statistic used in MLB.
The perceived significance of the RBI is displayed by the fact that it is one of the three categories that compose the triple crown. In addition, career RBIs are often cited in debates over who should be elected to the Hall of Fame. However, critics, particularly within the field of sabermetrics, argue that RBIs measure the quality of the lineup more than it does the player himself. This is because an RBI can only be credited to a player if one or more batters preceding him in the batting order have reached base (the exception to this being a home run, in which the batter is credited with driving himself in, not just those already on base). This implies that better offensive teams —and therefore, the teams in which the most players get on base— tend to produce hitters with higher RBI totals than equivalent hitters on lesser-hitting teams.
