Phillippe Aumont, the second prospect acquired from the Mariners for pitcher Cliff Lee last off-season to appear on this countdown, is back in a position more comfortable to him after experiencing some hiccups in his progress during the 2010 season. Upon joining the Phillies organization, higher ups decided to move the young reliever into a starting role. Aumont struggled as a starting pitcher during his first season in the Philadelphia system, but remains a talented pitcher worthy of consideration as an excellent prospect. A first round draft choice (11th overall) by Seattle in the 2007 amateur draft, Aumont was a highly regarded hurler when he was traded to Philadelphia in 2009. In 2008, his first season as a professional, Aumont appeared in 15 games, 8 of which were starts, posting a 4-4 record with a 2.75 ERA and 50 strike outs in 55 2/3 innings in the Class A Midwest League. The following season, Aumont appeared exclusively as a reliever in High A and Double A, going 2-6 with a 3.
