A game-winning RBI (GWRBI) is a statistic that was used in Major League Baseball (MLB) from 1980 to 1988.
The batter on the winning team who batted in the third run would be credited with the game-winning RBI, even though the losing team scored four runs.
That the statistic "did not adequately distinguish the achievement it was meant to reward" was one of the criticisms that led to the statistic being retired.
[2] Since no RBI is credited when a run scores as the result of an error, stolen base, wild pitch, passed ball, balk - or when the batter grounds into a double play with a runner on third base and no outs, there were certain games in which no one got the game-winning RBI.
Statistically, the pitcher of the losing team who gives up the game-winning RBI is charged with a loss; the pitcher of the winning team who finished the last half-inning before the game-winning RBI is hit would be credited with the win (with certain exceptions).
