11/11/2007 - College PREP - Austin, TX Mark is a tall, lean RHP who has some pull power potential at the plate as well. On the mound he has pretty good balance and his arm works fine. He tends to drift forward early and loses some direction with the front side. Even with these issues, his fastball is fairly firm with some tilt to it. His breaker is tight with good downhill movement to it and his change has some sink. He throws it too hard right now. As he learns to stay back and working in a straight line he will see improvement in his location, movement, rotation and velocity. A young arm worth staying with.
