Grissom struck out five of the six batters he faced and was among those who stole the show on Saturday. His fastball topped 92 mph, with feel for the corners, and he made use of a swing-and-miss changeup with which he recorded most of his punch-outs. Grissom has flashed the makings of an average curveball over the past year, giving him the three-pitch arsenal that should allow him to start long-term. He still has room to add strength and already uses leverage well in his delivery, working with a stiff front side, generating advanced hand speed.
1/11/19 - Announced verbal commitment to Georgia Tech.
10/1/18 - The son of former big leaguer Marquis Grissom, has a long, athletic frame at 6-foot-2, 180 pounds. He pitches with a loose, quick arm from a high-3/4 slot and has a high leg kick. His fastball was 86-89 and he mixed in a downer curveball that was mostly 76-78. His changeup was 78-79.
