01/18/2013 - Baseball Factory National Spring Training at Pirate City Fie continues to show improvements in his baseball abilities. Foot speed has improved as he ran his best 60 time to date. Feet are active as he works to square balls up while presenting hands out front. He needs to play through balls more and soften hands to continue to improve defensive grade. At the plate is where Derek has improved the most through an athletic setup. Hands are quick, flashing bat speed through a level swing path. He loads well and shows a feel for the barrel with power numbers improving as he learns to use his lower half more. Mental makeup is a plus as he is very coachable and works hard to be the best player he can be.
