5-foot-9, 140-pound long lanky build. Solid at the plate, Dennison clocked an exit velocity of 84 mph. (58.69 mph bat speed average). (19.89 mph hand speed average). Starts in an athletic balanced stance with a compact arm bar load, then uses a quick toe tap stride. Has a loose upward swing plane, efficient bat speed and good extension on his finish. He found lots of barrels with loud contact. Line drive approach. Confident from the outfield, he displayed a position velocity of 80 mph; shows choppy consistent feet, a fluid natural exchange, and sure hands. Movements laterally were quick and he fields the ball out front. Consistent accuracy to the bag, used a high ¾ slot and a longer loose arm action. Projectable on the mound, used a longer loose arm action with a high ¾ arm angle while showing good consistent arm speed. Up-tempo type pitcher and shows decent effort. Balance point is tall with uphill in line shoulders during delivery. Lands square with a falling off finish. Threw his fastball 77-79 mph and topped out at 80 mph; has consistent command and running action with sharp movement. (Max spin 2167; Avg 2068). Showed glove side control and sweeping action on his 1/7 curveball (66-70). (Max spin 2138; Avg 2034). His changeup (70-72) shows decent control and fading action.
