Run batted in or RBI is a statistic used in baseball and softball to credit a batter when the outcome of his at-bat results in a run being scored, except in certain situations such as when an error is made on the play. The first team to track RBI was the Buffalo Bisons.

Common nicknames for an RBI include "Ribby" and "Rib."

The plural of RBI is "RBIs". A common mistake is to conclude that the plural should be "RBI" because "runs" is the pluralized noun, but the entire acronym is properly pluralized.

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

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

The perceived significance of the RBI is displayed by the fact that it is one of the three categories that compose the triple crown. In addition, career RBI are often cited in debates over who should be elected to the Hall of Fame. However, critics, particularly within the field of sabermetrics, argue that RBI measures the quality of the lineup more than it does the player himself since an RBI can only be credited to a player if one or more batters preceding him in the batting order reached base (the exception to this being a solo home run, in which the batter is credited with driving himself in). This implies that better offensive teams—and therefore, the teams in which the most players get on base—tend to produce hitters with higher RBI totals than equivalent hitters on lesser-hitting team.

Derek Sanderson Jeter ( /ˈdʒiːtər/; born June 26, 1974) is an American baseball shortstop who has played 18 seasons in Major League Baseball (MLB) for the New York Yankees. A five-time World Series champion, Jeter has been a central figure of the Yankees during their success of the 1990s and 2000s due to his clubhouse presence, on-field leadership, hitting ability, and baserunning. He is the Yankees' all-time career leader in hits (3,155), games played (2,472), stolen bases (342), and at bats (10,066). His accolades include twelve All-Star selections, five Gold Glove Awards, four Silver Slugger Awards, two Hank Aaron Awards, and the Roberto Clemente Award. Jeter is the all-time MLB leader in hits by a shortstop, and the 28th player to reach 3,000 hits.

The Yankees drafted Jeter out of high school in 1992, and he debuted in the major leagues in 1995. The following year, he became the Yankees' starting shortstop, won the Rookie of the Year Award, and helped the team win the 1996 World Series. Jeter continued to contribute during the team's championship seasons of 1998–2000; he finished third in voting for the American League (AL) Most Valuable Player (MVP) Award in 1998, recorded multiple career-high numbers in 1999, and won both the All-Star Game MVP and World Series MVP Awards in 2000. He has consistently placed among the AL leaders in hits and runs scored for the past ten years, and since 2003 has served as the Yankees' team captain.
