Kemp was traded from the Cubs to the Athletics for minor-leaguer Alfonso Rivas on Monday, Susan Slusser of the San Francisco Chronicle reports.
Kemp filled a bench role for the Astros and Cubs last season but didn't do much at the plate, hitting .212/.291/.380 in 279 plate appearances. With the ability to play second base and all three outfield positions, Kemp should be a useful bench piece for the always-creative Athletics this season, but he's unlikely to play enough to be much of a fantasy asset or to hit well enough if he does get unexpected time.
