RHP Jack Roventini (Arrowhead, 2025) was a right-handed arm that caught attention on Tuesday. Listed as 6-foot-1, 175 pounds, Roventini showcased a fastball that topped at 86 mph and contained life through the zone. With an athletic delivery that saw him stay dynamic and quick through his motion, Roventini displayed a whippy arm action that came from a three-quarter arm slot. Through the delivery, he featured a high, closed tuck and was short out of the glove. The incoming junior worked efficiently and with a commanding presence on the mound as he mixed in a slider that had sharp, late break to it. The right-hander also flashed a changeup that contained some late fade to it. Roventini punched out two batters in his work across two hitless innings.
