2026 Fantasy Baseball Player Profile

The "Cuban Missile" turned back the clock in 2025, delivering one of the most dominant relief seasons of his storied career. Serving as the primary closer, Chapman posted a microscopic 1.17 ERA and struck out 35% of batters faced. His control, often a bugaboo, was surprisingly sharp, leading to a sub-1.00 WHIP. 

2026 Outlook: entering his age-38 season, Chapman remains a high-leverage weapon. While age-related decline is always a risk, his 2025 performance suggests he has plenty left in the tank. He enters 2026 as the unquestioned closer for a contending Red Sox team, offering elite save potential. After signing a one-year deal with Boston in December 2024, Chapman silenced critics who thought his 2024 resurgence in Pittsburgh was a fluke. He is now closing in on 400 career saves, a milestone that should keep him motivated to maintain his velocity and command.

AVG, OBP, SLG, ERA and WHIP are season-to-date through each game, not that game alone — so the column reads as a trend and its last value is the season figure. They stay season-to-date when the log is filtered by opponent; the figure for the filtered games is the one in the Total row. The second game of a doubleheader is marked (2).
