Topping out at 99.6 MPH, Martes’ fastball has some serious heat. It doesn’t give him much swing and miss though with a modest 9.5% rate, but it an effective setup for his off speed pitches.
A lethal curve is his secret weapon, and when you can generate a swing on a ball that hits you, you know you have good stuff. His plus curve generated 35.1% out of zone swings and a 17.9% whiff rate.
Martes’ changeup doesn’t look all that different from his changeup at times – aside from the fact that it comes it about 10 MPH slower. He gives up a lot of contact on this pitch with a 95.7% in zone rate, but only allowed a .154 BABIP.
