– The Philadelphia Phillies fired General Manager Ruben Amaro Jr. on Thursday, completing a cycle of turnover for a team going through its worst season in 43 years.

Manager Ryne Sandberg resigned in June, and Andy MacPhail was hired to replace outgoing President Pat Gillick after the season.

Assistant General Manager Scott Proefrock replaces Amaro as interim general manager. MacPhail hopes to hire a new GM before the end of October. He hasn't made a decision on interim manager Pete Mackanin.

The Phillies are on pace to lose 100 games for the first time since going 47-107 in 1961.

Amaro rose from team batboy in 1980-83 to playing for the Phillies for five seasons in the 1990s. He guided the Phillies to the 2009 NL pennant, three division titles and most wins in franchise history (102) in 2011.
