David Robertson 2009

In 30.1 innings pitched for the Yankees, David Robertson struck out 36 batters and walked 15. Yes, he's wild. But his talent for striking batters out is so good that he'll be an effective pitcher, even if his control never improves. As a 23 year old who still qualifies as a rookie, there's a chance he'll develop to be one of the top relievers in the game. His minor league strikeout rates were absurdly high...completely in line with what he did in the majors. John Sickels recently rated Robertson as the Yankees 14th best prospect. Either the Yankees have a great minor league system, Sickels doesn't like relievers, or Sickels really doesn't like short pitchers.
