About Mark Bellhorn
Mark Christian Bellhorn is an American former professional baseball infielder. In his ten-year Major League Baseball (MLB) career, Bellhorn was best known for being the starting second baseman for the Boston Red Sox during their 2004 World Series championship season. On August 29, 2002, Bellhorn became the first player in National League history to hit a home run from both sides of the plate in the same inning, doing so in the Cubs' ten–run 4th inning at Miller Park. Bellhorn also tied a team record with five RBI in the inning. His 2002 campaign was a record-setting season for the Cubs: his 27 home runs was the most-ever by a Cubs switch-hitter, and he became the first player in Cubs history to hit a home run from all four infield positions.
