Heyne has gotten stronger in the past year, adding lean muscle mass, and now stands 6-foot-1, 186-pounds. The right-handed hitter’s hands works really well with strength at contact and quickness through the zone to produce gap power with a top exit velocity of 90 mph. He ran a 7.61 60-yard dash and threw 85 mph across the diamond with a clean arm swing and carry. A two-way player and right-handed pitcher, Heyne works from a ¾ slot with an up-tempo, aggressive delivery. Good hip turn at the top of his leg lift and long stride down the mound, to uncoil his hips with an athletic finish and his arm works well out front. Fastball has tilt and sink at 79-83 mph. Releases his curveball from the same window at 71 mph, the pitch has good shape and 10/4 rotation and flashes later break at times. Moving forward, Heyne has two-way potential and will be fun to follow this coming high school season.
