07/10/2012 - College PREP - Minneapolis, MN Dalton is a broad 1B that will graduate in 2013. Feet are active as he displays proper footwork around the bag and displays clean hands. For defensive grades to improve, he needs to attack ground balls more, play through while presenting hands more out front. He gets rid of the baseball quickly with accuracy on his throws but needs to build more arm strength and carry, through a long toss program. At the plate, Mattson shows a balanced setup and is selective at the plate. He makes consistent contact and works to keep hands inside the ball but needs to shorten swing path and improve bat speed to improve hitting grade. Power numbers will increase as he learns to use his lower half more through the swing. Dalton has abilities with a lot of room to improve.
