Threw a complete game in ISA Stars Black’s victory over CBT. In control from the first inning on. Fastball, curveball, change up mix, flashing control of all his pitches. Fastball was 75-77 mph with some cutting action, curveball 64-65 mph with a mix of 11/5- 10/4 shape, and a change up at 68 mph with fade. Changeup proved to be his go to out pitch when needed.

Path works slight uphill, average bat speed, 80 mph exit velocity from the tee. Defensively arm plays at 69 mph across the diamond, long ¾ slot. 8.01 runner in the 60. On the mound arm plays similar. Fastball is straight, 68-71 mph. Curveball has 11/5 shape, 63-64 mph. Changeup fades, 63-68 mph.
