05/28/2020 - 2020 Under Armour Showcase: Baseball Factory's National South Mason is an exciting RHP prospect with big upside potential. He stands 6'5"/205 and is athletic with a controlled, repeatable delivery. His arm works free and clean and he has a fluid arm stroke that produces low effort upper 80s velocities. In his outing he struck out 4 of the 8 hitters he faced and added in a curve that had good depth and quite a bit of downward action from his high 3/4 release point. There is much more in the tank making Mason a prospect to watch closely.
