RHP/1B Isaiah Dufek (Heritage Christian, 2027) is listed at 5-foot-10, 147-pounds with a long, wiry frame that should fill with more size and strength. Dufek impressed our staff with the bat and on the mound. Dufek showed consistent barrel awareness with the ability to hit line drives to both gaps with a short and compact right handed swing. On the mound, his upper-70s fastball displayed hard running action to the arm side and showed feel for the strike zone. He also featured a breaking ball and a changeup and has feel for both secondary offerings.
