2003 Philadelphia Phillies season

The 2003 Philadelphia Phillies season was the 121st season in the history of the franchise. The Phillies finished in third place in the National League East, 15 games behind the Atlanta Braves, and five games behind the 2003 World Series champion Florida Marlins, who were the NL's wild-card winner. The Phillies were managed by their former shortstop Larry Bowa, as they played their final season of home games at Veterans Stadium, before moving the club to Citizens Bank Park in 2004.
