2025 Fantasy Outlook
Castellano was one of the Phillies' best pitching prospects, but the Twins selected him in this offseason's Rule 5 draft so his development as a starter may be put on hold. A 23-year-old righty with a projectable 6-foot-3 frame, Castellano struck out 86 in 63.1 innings at High-A and logged a 3.79 ERA, 0.99 WHIP and 50:9 K:BB in 40.1 innings over eight starts at Double-A. He'll probably be eased into a low-leverage role as the Twins will look to keep him on the big-league roster all season in order to retain his rights. Castellano could be stretched out again in 2026.
