Mason Williams: SS/C, (2027) St. Johns Jesuit, OH. 5-foot-9, 135-pound projectable build. (58.6 mph bat speed average). (19.2 mph hand speed average). Began in a tall narrow stance with a smooth controlled load, then used a small leg kick. Bat speed is electric quick, shows a short simple swing plane and balanced finish.
