Charlie Manuel has been managing the Phillies since the beginning of the 2005 season, during which time the team has posted a record of 780-636. From 2007-11, the Phils won five straight division titles under Manuel, and in 2008 they captured a World Series title. The Phillies returned to the Fall Classic in 2009, though they were denied a repeat championship by the Yankees.
Manuel built up an impressive track record as a manager in the minor leagues in the 80s and 90s before taking over as the Indians' hitting coach in the mid- to late-90s. He became the club's manager in 2000 and led the Tribe to an AL Central Division Championship in 2001. In parts of 12 seasons as a big league manager, Manuel has tallied exactly 1,000 victories against 826 losses.
Among current Major League managers, only the Twins' Ron Gardenhire and the Angels' Mike Scioscia have longer tenures than Manuel had with the Phillies until today.
