06/05/2019 - 2019 Under Armour Showcase: Baseball Factory's National Florida Jack is a strong RHP prospect who will graduate in 2020. On the mound, Jack works with a loose arm and extends through his release. He stays inline towards the plate and finishes with his chest over his front knee. Jack shows a two pitch mix with his fastball topping out at 87mph with cutting action. Breaking ball shows to be a plus pitch, sitting from 76-78mph with late 11-5 break. Overall, Jack is a talented prospect who will be one to follow going into his senior season.
