12/06/2015 - College PREP - McCook (Chicago), IL Calderon stands at 5-foot-9 and 175 pounds and worked out in the OF and behind the plate. A right-handed hitter, he maintained a quiet head and offered some strength and bat speed to an approach built to hit the ball back up the middle. He generated his stroke primarily from his hands and arms, would benefit from work to incorporate his lower half and core. There is upside based on this potential to improve. Behind the plate, he posted release times between 2.25 and 2.32. His exchange was solid, though his footwork tended to be a little big and out of rhythm with his upper half. He sat well to receive and showed solid hands. He got down well to block and recovered to his feet well also. In the OF, he was aggressive to the ball and showed some body control. His throws were on line, though his release was a little slow and without ideal momentum through the play on the ball.
