"Honestly, since high school I haven't done anything different," Cortes said. "Obviously, I've matured to where I've had my ways of pitching and realized what I could do and what I could not do and where I can afford to be with my mistakes. Obviously, at 87, 88, 89, 90 [mph], compared to a 97-98, you have no room for error. I think what's different for me is that I hide the ball real well, and it has some life getting to the plate, and that's what's made me have more room for error. I cannot leave the ball up, but have that advantage where if I leave it up, it's sneaky enough where I can get it by someone or get some bad contact. That's what has helped me."
