SF - He's not too old for league level (23), but this is his 2d season at A+ (and portion of a 3d). He's been > a K an inning at every stop except the GCL. What has been his achilles is his BB rate at Potomac in 2010 (sss) and 2011. It seems he has his BB rate way down. Was wort ranked on any prospect tracker? what does he throw?
