Quad Cities River Bandits (Low A, Astros)
50/No. 4 Starter
Four-seam fastball 91-93, mild arm-side run, shows command potential, locates to both sides; three-way action, shows two-seam variant at 88-90, can cut it, advanced pitch
11/5 but inconsistent shape; shows ability to spin it with downer rotation; mainly in-zone at present, did bury several down low
Consistent arm speed; quality deception; flashes above average fade
Signed out of Venezuela, Perez is almost four years younger than most of his counterparts in the Midwest League. He's been bouncing back an forth between starting and relieving, but he shows the ingredients of a future starting pitcher. He already touches 95 with a fastball that jumps out of his hand with some arm-side run, and he shows an advanced ability to manipulate it with two-seam and cut variants. The curve is inconsistent at present, but when he stays on top it features 11/5 shape with depth. His changeup is an advanced pitch that he throws with proper arm speed to generate deception with late fade down in the zone. The command is spotty at times but throws enough strikes when the mechanics are right to project a future filling up the zone. All told, Perez has the frame to be an innings eater with a quality fastball and two at-least-average secondaries.
