Wiersma

8/1/18 - SoCal Underclass Games - Six-foot-4, 170-pounds, large frame with strength from top-to-bottom. Wiersma shows a quick-to-fast arm with a short, compact action through to a ¾ slot. Effort is easy/regular. Landing can be stiff, but it's square to the target and online. Fastball shows late running action. When pitch has downhill plane it's an above average pitch. Curveball projects well with it's late, sharp biting action from the same slot and arm speed. Pitch generated swing-and-miss along with weak contact throughout his outing. There's feel for a changeup that flashes late fading action. Wiersma faced four hitters: F4, K, 6-3, K.
