Scott Sizemore

While the Oakland A's had a successful season by all means in 2012, the infield is bound to be a lot better in 2013. 

The A's went out and got Hiroyuki Nakajima and Jed Lowrie, and they will return formerly injured Scott Sizemore in 2013. Brandon Moss hit .291 in 2012, and Donaldson hit .284 in his last 225 at-bats (for the regular season). Sizemore doesn't have too much on his resume, but he is a talented player who may start at second base.

It’s hard to call Scott Sizemore anything but a disappointment in 2010.  Thought to be a sleeper second baseman entering the season, he lasted until mid-May before being sent back to Triple-A.

He was solid while there, hitting .298 with nine HR, 37 RBI, 49 R, and two SB.  With injuries piling up in Detroit, the Tigers ultimately brought him back to the majors, though they were still hesitant to depend on him.
