Biggest Losers (Worst win % by a Phillies manager)
The team’s 24th manager, Hans Lobert managed exactly two Phillies games in 1938 and his squad lost both of them. He was then asked back in 1942, and went 42-109, for a slightly better .278 record, which is still the fourth-worst % in Phillies managerial history.
In the second half of the Phillies’ inaugural season Blondie Purcell replaced the franchise’s first manager Bob Ferguson, who had gone 4-13 (.235), but Purcell, who managed 81 games, finished worse (.160).
In franchise history, Gary Varsho and Dusty Cooke are the only two skippers with exactly .500 records. 19 Phillies managers finished their tenures with a winning record, including Andy Cohen, who managed exactly one game in 1960, and the team won.
Current Phillies manager Joe Girardi has a .497 record over his first two seasons at the helm.
Most losses by a Phillies manager
Gene Mauch leads all Phillies skippers with 684 losses during his term from 1960-68. Charlie Manuel comes in second with 636, but has a better % (.551) than Mauch, since he had significantly more wins over a longer managerial tenure (2005-13). They’re the only two managers in franchise history with 600+ losses, though as this exercise clearly shows, many managers didn’t last very long.
