The Red Sox best Latin American pitching prospect only two years ago, righthander Stolmy Pimentel is only 21 this year, but some scouts are already thinking about pulling the plug on his development. His 94mph fastball has good late life, and he uses it well, balanced against a curve, change and developing sinker that could all be serious pitches in another couple of years, but the phenom's performance in 2011 was phenomenally bad, 'highlighted' by a perfect 0-9, 9.12, 1.95 turn in fifteen AA starts. He may need to be broken down and built up again from scratch to be a factor in MLB, which means you can probably forget about 2012 and even 2013 for the young Dominican.
