The Dodgers' first round pick in 2007, righty Chris Withrow has been growing into a premium power arm, and that's exactly what the Dodgers are looking for. His fastball still lives around 93 but can hit 98 with good movement. His improving curve is a strikeout pitch, an 11-5 hammer that he's comfortable throwing in almost any count. A potential middle-rotation candidate who's already showing superior makeup, Withrow went 6-6, 4.20 at AA Chattanooga in his second tour of the league, a substantial improvement on an aberrant 2010. He could move quickly once he gets his walks back under control, especially if the Dodgers suffer injuries in 2012.
