Showed in a game against Worcester Academy- FB - 86-88 and BB- 76-78 with plus leverage. Solid showing early in the high school season
Krystofolski is an athletic 6-foot, 170 pound right handed pitching prospect. The delivery is simple and clean. He separates well at the top before heading down the mound in line with home plate. The arm is loose and creates some late run on the fastball. The slider is a good pitch. The spin is tight, with late biting action. He also shows good action and arm speed on his changeup.
