In baseball, a run batted in (RBI) is awarded to a batter for each runner who scores as a result of the batter's action, including a hit, fielder's choice, sacrifice fly, bases loaded walk, or hit by pitch. A batter is also awarded an RBI for scoring himself upon hitting a home run. In Major League Baseball (MLB), a player in each league wins the "RBI crown" or "RBI title" each season by hitting the most runs batted in that year.
The first RBI champion in the National League (NL) was Deacon White; in the league's inaugural 1876 season, White hit 60 RBIs for the . The American League (AL) was established in 1901, and Hall of Fame second baseman Nap Lajoie led that league with 125 RBIs for the Philadelphia Athletics. Over the course of his 27-season career, Cap Anson led the NL in RBI eight times.Babe Ruth and Honus Wagner have the second- and third-most RBI titles, respectively: Ruth with six, and Wagner with five. Several players are tied for the most consecutive seasons led with three: Anson (twice), Ty Cobb, Rogers Hornsby, Ruth, Joe Medwick, George Foster, and Cecil Fielder. Notably, Matt Holliday won the NL title in 2007 by one RBI over Ryan Howard, only overtaking Howard due to his performance in the 2007 National League Wild Card tie-breaker game. Had Howard won the 2007 title, he would have led the NL in a record four consecutive seasons from 2006 to 2009. The most recent champions are Mike Trout in the American League, and Adrian Gonzalez in the National League.
