Semien committed three errors as the White Sox's starting third baseman Tuesday. This was already his third start at third base since being recalled on Sept. 3, and he already has four errors at the position in that stretch. He has 12 errors total in 401.1 MLB innings across third, second base, and short, but his hitting in the minors (.881 OPS) will keep his name in the mix for an infield spot in 2015.
