Perez is 5-10 with an athletic frame that has some lower half strength and plenty of projection left to it. He throws from a low three-quarters arm slot, short loose quick arm action with some effort to his delivery. Shoulders are level and closed, lands slightly closed with some fall off in his finish and some recoil. Fastball was 78-80, touching 81, pitch has some boring action initially with some late armside run that has a bit of depth. Curveball was 64-68 with some armspeed and sharp 11/5 break. Change-up was 71-72 with good armspeed and some fade. Perez showed ability to move the fastball around the zone. Worked a quick scoreless inning and picked up a strikeout swinging on the fastball up and in.
