Aroldis Chapman aims to replicate career-best 2025 closing performance

Aroldis Chapman is coming off a career-best 2025 season for the Boston Red Sox, where he posted a 1.17 ERA over 67 appearances. His success was attributed to a career-low 6.6% walk rate, showcasing newfound control. Chapman's overpowering arsenal, featuring 98-99 mph fastballs, an untouchable slider (34% putaway rate), and an effective splitter, made him virtually unhittable. He is expected to handle the ninth inning in 2026 if he remains healthy.
