RHP Cooper Sieben (Rock Creek, 2025) had a standout showing on the mound at Sunday’s scout day. At 6-foot-3, 200-pounds, Sieben is an easy mover down the mound, using a loose, whippy arm to run his fastball up to 85 mph, consistently sitting between 81-84 mph with a top spin rate of 2200 RPM. The righty’s best secondary pitch at the moment looks to be his slider which he threw at 73-74 mph with tight 2300+ RPM spin. Sieben paired that with a curveball for strikes at 71-73 mph and a low spin changeup at 75-76 mph.
