Scott Sizemore went 0-for-4 and committed his 16th error in Wednesday's loss to the Angels. He has 13 errors in 80 games at third base for the A's. Now, he's still learning the position after spending most of his career at second, but that's still too many. He's been a solid hitter, and since he's making the minimum, the A's certainly have to be considering going forward with him as a 2012 regular. Still, upgrading at third base this winter can't be ruled out.
