| Notes | ||
| Luis Castillo remains a reliable innings-eater, but his 2025 profile showed continued erosion in strikeout rate (21.7% K%) and rising hard contact (46.5% HardHit), limiting his fantasy ceiling. Projections reflect more of the same: solid ratios and workload, but middling strikeout totals compared to the top fantasy arms. Castillo is still a dependable rotation anchor in deeper formats, though fantasy managers should no longer pay for peak-era upside. Kelly Kirby - FantasyPros | ||
| His age is increasing and his strikeout rate is plummeting - a disastrous combination for a pitcher. There are more talented, lively, and exciting arms being drafted behind him with more upside that I strongly prefer. Anthony Gambale - Roto Street Journal | ||
