The Astros have extended the contract of general manager Ed Wade through 2012, a Major League source has confirmed. The club has not commented, but an official announcement is expected later Saturday. Wade was hired on Sept. 20, 2007, and is entering his third full season as the club's 11th general manager. A veteran of 33 Major League seasons, Wade spent eight years as the general manager of the Philadelphia Phillies (1998-2005) before coming to the Astros.
