06/10/2012 - College PREP - Medford (Boston), MA Marshall is a big, solid, 1st baseman who will graduate in 2013. Defensively, Marshall has playable hands and feet, and he tries to keep the ball in front. He has a clean exchange and throw with some carry and accuracy to his target. More sure hands and playing through the ball can help defensive abilities improve. At the plate, Marshall has a tall set-up, a square stride, and good balance. He can work the ball gap-to-gap and he uses his lower 1/2 well. More load and better timing can help defensive grades rise.
