Uncommitted. Athletic 5-foot-10, 175-pound frame. Osmanski was electric Thursday night as he struck out four batters through three and ⅔ shutout innings, while allowing no hits. The right-hander operates from a simple, controlled delivery with a high leg lift while having a drop/drive approach. Loose, full, clean arm action from a ¾ slot. His fastball sat 82-84 mph and topped out at 86 mph while having a spin rate up to 2450 RPM. He mixed in a slider that sat 73-75 mph with sharp actions.
