03/19/2017 - College PREP - Corpus Christi, TX Kullen is a solid, muscular RHP who will graduate in 2017. Delivery is sound / repeatable allowing his arm action to work free to the plate through a submarine arm action. He shows good tempo through a strong balance point. Fastball showed a range of 78-81 mph with tailing action. Breaking ball displays 3/9 shape with sweeping break. He maintains arm speed on his changeup with sinking action but throws too hard with speed variations being too close to fastball. Stock on the mound will continue to rise as he builds more arm strength through a long toss program. Kullen has abilities with a lot of room to progress his abilities on the mound.
