A run batted in or runs batted in (RBI[1]) 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 which allows a teammate on a higher base to reach home and so score a run, then the batter gets credited with an RBI.
Common nicknames for an RBI include "ribby" (or "ribbie"), "rib", and "ribeye". The plural of "RBI" is a matter of "(very) minor controversy" for baseball fans:[3] it is usually "RBIs", in accordance with the usual practice for pluralizing initialisms in English;[4][5] however, some sources use "RBI" as the plural, on the basis that it can stand for "runs batted in".[3][4]
