Oakland Athletics (2010 record: 81-81)
The Oakland Athletics finished last season with a .500 record after three consecutive losing seasons. They were able to do so thanks largely to an excellent young rotation, a good bullpen and a solid defense. Little of what they accomplished was owed to their offense—which finished 11th in the league in runs scored.
In an effort to improve the offensive attack, the front office bid adieu to DH Jack Cust and outfielder Rajai Davis and replaced them with DH Hideki Matsui and outfielders David DeJesus and Josh Willingham.
I’m not sure I would have cut ties with Davis, who is just starting to reach his potential, but Billy Beane and company probably saw him as redundant due to the presence of Coco Crisp. Willingham and Matsui should provide quite a bit more power to a lineup devoid of power bats.
