Zack Ziemke: OF/RHP, (2027) St. John's Jesuit, OH. 6-foot, 155-pound. (56.1 mph bat speed average). (17.3 mph hand speed average). Began in a balanced wide stance with a controlled load, then used a small controlled stride. Bat speed was developing, used an uphill swing plane and high good extension on his finish. In his round he found multiple barrels. Gap to gap approach. From the outfield, he made throws to the infield at velocities up to 79 mph. Projectable on the mound, showed good arm speed, he had a consistent quick arm action and a high ¾ arm angle. Drop-and-drive type pitcher and shows easy effort. He has in line shoulders and an athletic strong balance point. Lands square with an athletic finish. (Max spin 1916; Avg 1821).
