Mason Kessinger: LHP/OF, (2027) Perrysburg, OH. 5-foot-9, 125-pound. Began in a balanced stance with a smooth load, then used a short stride. Had a level swing plane, developing bat speed and balanced finish. Pull side up the middle approach. His best position velocity in the outfield was registered at 78 mph. In the 60-yard dash, recorded a time of 7.4. Projectable confident on the mound, showed developing arm speed, also used a long loose arm action with a ¾ arm angle. Tilt-and-topple type pitcher who uses some effort. Showed consistent balance point and downhill shoulders. Lands square with an athletic finish. (Max spin 2112; Avg 1945).
