A well-rounded righthander from Ohio State drafted the Twins in the first round of 2010, Alex Wimmers was that rare example of a college pitcher who already showed control of three pitches, including a genuine plus changeup, before ever setting foot on a professional mound. A big-game pitcher who excelled under pressure in college, Wimmers showed consistent shutdown ability whenever the Buckeyes needed it, but he seemed more than a little wild at high-A Fort Myers last year, though he did calm down later in the year after a little off-field work on his approach to the craft, and looked close to his old self by the end of the season. His uncanny ability to outsmart hitters rather than blow them away with his stuff has always been his primary asset, so it should be no real surprise that his effectiveness hinges on the sharpness of his mental game, and that's never been as true as 2013, when he'll be working his way back from late-season TJ surgery. He will need patience and wile in order to rediscover and/or reinvent his delivery as a result. If the enigma of his ability/performance dichotomy can be untangled, he'll be an asset, though, no matter whether he comes as part of the rotation or the bullpen.
