Pitch Type Future Grade Sitting Velocity Peak Velocity Report
FB 70 92-95 98 Explosive pitch; above-average arm-side run, natural tailing action, late life; deception and extension help velocity play up; heavy pitch down in the zone, shows feel to elevate; present command limits utility to a plus pitch, minimal command refinement and consistency will push to a plus-plus weapon
CB 70 83-85 85 Hard curveball with slider-like velocity and movement; tight rotation, late 11-5 break; Plus-plus movement, repeats arm speed effectively; can work in zone or as a chaser, will front-door early and late in counts; ability to freeze hitters, tough pitch to identify out of the hand.
CH 55 87-88 89 Firm change with below-average separation but above-average tumble and moderate fade; plays well off fastball plane, consistent arm speed, shows feel; limited swing-and-miss potential, movement and feel suggest above-average projection as complimentary pitch.

Martes has frontline stuff in the form of two potential 70-grade pitches thanks to a powerful lower half and premium arm speed. His delivery is inconsistent pitch-to-pitch right now, and his firm foot strike and landing requires attention. But the physicality suggests ample room for projecting refinement and he already demonstrates an advanced feel for commanding the baseball in spite of his mechanical inconsistencies. There's above-average potential here for commanding what is already a nasty arsenal.

He's aggressive on the mound, pitching with swagger and moxie. With standard command improvement and the greater consistency that comes through repetition Martes has the potential to develop into a top-of-the-rotation starter, with a high floor at the back end of a Major League bullpen on the strength of a dynamic fastball-curve combination that could devastate in short bursts.
