06/01/2014 - College PREP - Medford (Boston), MA Derek is a 5'11/140 lbs SS that will graduate in 2016. Defensively, he worked his efficient feet to a good fielding position with plus body control. He fielded in front with soft hands and used momentum to throw to his target. He displayed a quick release which allowed his arm to work better than his velocity suggests. Adding arm strength and overall strength over the next two years will be instrumental to his development and next level play. Offensively, he got to his hitting position on-time and maintained his balance throughout the swing. Becoming more direct with the barrel and refraining from wrapping the bat around his head will increase bat speed and hit ability. In all - Duffy is a young player with some raw ability that has time to improve for next level play.
