Santiago Castellanos
Pitching scouting report · 80Grade
Scouting summary
The most reasonable long-term projection is a relief role unless he makes a real jump in strike-throwing and secondary quality. The 2025 strikeout rate suggests there is some bat-missing ability, but the limited 2026 look raises enough command concern to keep the starter path in check. Because he is so young and still physically developing, there is a pathway to a low-leverage or middle-relief outcome if the arm strengthens and the delivery settles. The ceiling is tied to whether he can add playable velocity and at least one reliable secondary pitch; without that, he profiles as a fringe up-down arm.
