A "run batted in" (RBI) is a statistic in baseball that measures a player's effectiveness in driving in runs. When a batter hits the ball and a runner scores as a result, the batter is credited with an RBI. This can happen through various means, such as a hit, a sacrifice fly, or a walk with the bases loaded. RBIs are important for evaluating a player's contribution to their team's offense. Players with high RBI totals are often seen as clutch performers who can deliver in critical situations. The statistic is commonly used alongside others, like batting average and home runs, to assess a player's overall performance in the game.
