10/10/2018 - Arizona Senior Fall Classic Calvin is a long and athletic 2019 LHP prospect that works hard and showed the ability to play the field as well. At the plate, Calvin starts in a squared stance, gets his front foot down on time, and stays balanced through contact. He needs to continue to get his hands into the drive position and attack the inside part of the ball. On the bump, Calvin separates on time, extends thru his delivery, and works north to south. He shows the ability to adjust pitch to pitch. His fastball shows tail, his curveball has 11-7 break, and his changeup has a good differential speed from his fastball. Calvin will continue to improve with experience and we hope to see his progress in the future.
