Top Red Sox minor-league prospects
6. Stolmy Pimentel, RHPTeam: Portland (Double A)
Scouting report: The Red Sox drafted him as an international free agent in 2006, and he is in the Sea Dogs rotation. Pimentel, 21, struck out more than 100 batters with Greenville in 2009 and again with Salem last season, but is struggling with Portland this season. Pimentel likely is two years away from the majors, so he has time to develop his 12-6 curveball and changeup.
