"In a game now where guys are trying to throw 100 and elevate and throw 90 mile-per-hour sliders, he just has such a relentless sinker that it just doesn't come above your knees," Kelley said. "He doesn't leave one over the middle very often. He really pounds that sinker down at the knees. Guys just beat it into the ground and can't hit it. Just watching him every single pitch, whether it's a ball or a strike, it's down there. Over and over and over. He knows what he has, and he's really good at repeating it."
