Robert Pershing "Bobby" Doerr (born April 7, 1918) is a former Major League Baseball (MLB) second baseman and coach. He played his entire 14-year baseball career for the Boston Red Sox (1937–51). He achieved a batting average over .300 in several seasons, and set Red Sox team records in several statistical categories despite missing one season due to military service during World War II. Doerr is a member of the Baseball Hall of Fame.
After he retired as a player, Doerr served as a scout and a coach, including work with Carl Yastrzemski before his Triple Crown season. As of November 4, 2016, Doerr is the oldest living former major league player. He is also the last living person who played in the major leagues in the 1930s, and the oldest of only three living people who made their MLB debut before U.S. involvement in World War II.
