The signed to a one-year deal, bringing the former ace to bolster a young starting rotation.
Sheets spent the entire 2009 season nursing an injury but passed the Athletics' physical prior to his signing.

Beware of Sheet's injury risk as he missed significant portions of four out of the last five seasons.
