Scott Sizemore homered and doubled to knock in three Oakland runs in Tuesday's 7-0 win against the Mariners. He also walked. Sizemore has been a butcher at third base for Oakland after spending most of his career at second, but he's been decent offensively. He's batting .244/.340/.397 with 11 homers and 56 RBI in just 365 at-bats. Since he's making the minimum, the A's certainly have to be considering going forward with Sizemore as a 2012 regular. Still, upgrading at third base this winter can't be ruled out.
