OAKLAND, Calif. — Oakland Athletics manager Bob Geren has received a one-year contract extension through the 2010 season, with a team option for 2011.

Geren is 151-172 in two years running the A's after being promoted from bench coach in November 2006 by general manager and close friend Billy Beane. Oakland finished third in the AL West last season at 75-86.

Geren played five major league seasons as a catcher with the New York Yankees and San Diego before his coaching career.
