The Oakland Athletics' 2007 season was their first since 2004 in which they defended a title. The A's were without Frank Thomas (Toronto) and ace Barry Zito (San Francisco), both players who the A's lost to free agency. They filled the space left by Frank Thomas by signing free agent catcher Mike Piazza to a one-year contract worth $8.5 million to be the team's designated hitter. They were also without Ken Macha, their former manager who was fired after four seasons with the team and replaced by Bob Geren, as well as third-base coach Ron Washington, who accepted the managerial position of the Texas Rangers. It was their first losing season since 1998.
