He also showed a slider-like breaking ball for strikes at 70 mph with spin up to 2,375 RPMs. He had good feel for the pitch and was able to work it lower for swings and misses. A right-handed hitter with a waggling start in his hands before he gets the bat vertical and back elbow out. Starts with a slightly open stance and a narrow base. Aiming to work compact to the ball and drive it. Rotates well through contact and was able to show off the bat speed. Solid round overall during BP.
