What happened: Rocco Maniscalco, a 17-year-old shortstop, registered a 97 mph throw during workouts at the MLB Draft Combine. The arm strength stood out among the prospects on display at the event.

Why it matters: Premium velocity from the left side of the infield is a carrying tool that scouts weigh heavily, and posting it at 17 raises a prospect's profile ahead of the 2026 MLB Draft. Combine performances like this can move a player up draft boards as front offices finalize their evaluations.

What to watch: Watch where Maniscalco lands when the 2026 MLB Draft board takes shape and whether teams project him to stay at shortstop.
