Due to a "horrendous stretch of the season" where the Oakland A's lost nine straight games, team manager Bob Geren was fired today. "Geren's season took a turn for the worst last month when then closer Brian Fuentes criticized his manager for a lack of communication and inconsistent handling of the bullpen," reports the Chron. "The team's former closer, Huston Street, piled on, telling The Chronicle that Geren was one of the worst people he had encountered in the world of sports."

Ouch.

Arizona Diamondbacks' noted manager, Bob Melvin, will take over tonight when the A's take on Chicago.
