06/05/2018 - 2018 Under Armour Showcase: Baseball Factory's National South Brennan has an ideal pitchers frame with long limbs and proportioned strength throughout. His fastball sits comfortably in the 92-94 mph range, touching higher, and it appears he is just playing catch. The ball jumps out of his hand, and on top of the big fastball, Brennan throws a slider, curve and change - all of which he has feel for. Overall, this is one of the top pitching prospects in the 2019 class.
