07/30/2017 - College PREP - Chicago, IL Jack is a tall, solid, and strong RHP who has a promising future on the diamond. Delivery is sound / repeatable allowing his arm action to work free to the plate. He shows good tempo through a strong balance point. Fastball showed a range of 73-76 mph with tailing action. Breaking ball displays 10/4 shape with gradual break. He maintains arm speed on his changeup with sinking action. Control is well above average as he throws strikes with all his pitches. Stock on the mound will continue to rise as he builds more arm strength through a long toss program. With 2 years to further develop, Jack has potential with time and room to progress his game.
