INF/RHP Robert Grosch (Fort Zumwalt North, MO; 2028) was one of the top overall performers on the day. Listed at 5-foot-10, 175-pounds, Grosch features developing strength throughout his frame. He has loose, strong hands and his right-handed swing works on plane and with quick-twitch through the hitting zone. Should be a young bat to know in the Missouri 2028 class. Defensively, he is a clean defender on the infield who plays with feel, is comfortable on the move and topped at 81 mph across. On the mound, Grosch showed a controlled, easy delivery with a clean arm action. He showed advanced feel for his three pitches, throwing each for strikes consistently throughout. His fastball worked mostly straight coming out of the hand clean, sitting in the upper-70s throughout. He turned to a curveball with 11/5 shape that landed in the bottom half of the zone, and a change-up that played with fade and depth.
