Tyler Kolek

Scouts knew about Kolek as one of the top 2014 targets in Texas when he broke his left arm in a collision at first base in March 2013. The injury ended his junior season, but Kolek kept himself in shape. When he went to the tryouts for Texas' Area Code Games team in late May, his fastball popped 99. A three-sport star who was drawing interest as a defensive end, Kolek decided to focus exclusively on baseball after the ACG tryout. Kolek then spent the summer establishing himself as the hardest thrower in a draft class full of velocity, and has maintained triple-digit radar gun readings all spring, hitting 100-102 mph regularly. Kolek's fastball sits 96-98 mph thanks to tremendous strength, coordination in his 6-foot-5, 245-pound body and surprising arm speed. Kolek is very athletic in his delivery has a very long stride, even for his size. Scouts consider Kolek's consistent top-end velocity unprecedented in the draft era for a high school pitcher. His fastball plays up beyond its pure velocity readings because of its heavy plus life, working downhill with sink. His dense fastball will likely be a groundball-inducing offering when hitters make contact. He throws both a curveball and slider, and the slider is a power pitch in the mid-80s that is his best secondary pitch and shows at least plus potential. His curveball has decent shape but he prefers the slider. He repeats his delivery and throws quality strikes. He has shown a changeup in showcases or in the bullpen but hasn't needed it in games. Kolek can lose his direction to the plate, working from the far first base side of the rubber and occasionally landing closed. But he has cleaned up his delivery this spring, leading to the consistent velocity. He has performed as expected as a potential top-five pick against small school Texas competition, striking out 60 percent of hitters against 6 percent walks. Scouts struggle think think of a physical comparison for Kolek and that lack of analogous players make scouts wonder how his body will progress as he ages. Strike-throwing ability and the development of his offspeed stuff will be the keys to his development, as he has the chance to develop into a power pitcher that fronts a rotation.
