The reigning World Series champions are facing a shakeup in their front office.

The San Francisco Giants announced Wednesday that managing partner and chief executive Bill Neukom will retire from his position after the season.

Neukom, who took over as managing partner for Peter Magowan in 2008, will be replaced by current Giants president and chief operating officer Larry Baer.

The San Jose Mercury News reported Wednesday afternoon that Neukom was asked to step aside by the executive committee of the team's ownership after a series of apparent disagreements over his stewardship of the team.

Hours later, the Giants said in a statement that they had planned to wait until the season was over to announce the news out of respect for the fans and the team.

Neukom and Baer were set to appear at a press conference in AT&T Park on Thursday morning.
