Run batted in

Run batted in (plural runs batted in, abbreviated RBI) 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 like when an error is made on the play).

Historically, the Buffalo Bisons were the first team to track RBIs. Major League Baseball did not recognize the RBI as an official statistic until 1920.

Common nicknames for an RBI include "ribby", "rib", and "ribeye". The plural of RBI is generally "RBIs", although some commentators use "RBI" as both singular and plural, as it stands for Runs Batted In.

Major League Baseball Rules

The official rulebook of Major League Baseball states in Rule 10.04:

(b) The official scorer shall not credit a run batted in

(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.
