Aroldis Chapman locked in a $13 million contract for 2027 after pitching beyond the 40-inning mark for the Boston Red Sox in their 4-0 win over the Pittsburgh Pirates on Saturday night, triggering a vesting option included in his extension agreement signed last September.
Chapman’s scoreless ninth inning in that game proved to be one of his most significant outings of the season, not for the result but for what it meant for his future. The veteran left-hander surpassed the innings-pitched threshold that automatically vests his 2027 salary, provided he passes an end-of-year physical.
The extension Chapman agreed to in September 2025 was structured with this specific milestone in mind. The deal guaranteed him $13.3 million in 2026, with the vesting option adding another $13 million for next season if he reached 40 innings in 2026. The two-year value of the agreement could reach $26 million if both conditions were met.
Chapman’s dominance in Boston over the past two seasons has made the investment worthwhile for the Red Sox. After winning American League Reliever of the Year in 2025 with a career-best 1.17 ERA and 32 saves, the 38-year-old has continued his elite performance in 2026. Through mid-August, he owns a 1.99 ERA over 40 innings with 27 saves, tied for sixth in Major League Baseball.
The Red Sox pitcher’s career trajectory before joining Boston made his resurgence all the more remarkable. After stints with the Texas Rangers and Pittsburgh Pirates in recent seasons where he appeared to be in decline, Chapman arrived in Boston in December 2024 with little fanfare. Yet he quickly reclaimed the closer role and has pitched at a level among the best of his career.
Chapman’s individual accomplishments this season extend beyond his vesting milestone. In July 2026, he set an all-time Major League Baseball record for strikeouts by a relief pitcher, recording his 1,364th career strikeout to surpass Hoyt Wilhelm. At 38 years old and in his 17th MLB season, Chapman has earned $189.6 million across seven teams while compiling 394 career saves, placing him ninth on the all-time list.
Red Sox interim manager Chad Tracy has praised Chapman’s preparation and work ethic as central to his sustained excellence. “When I get asked questions about him, I mostly revert back to the fact this guy’s preparation is so elite,” Tracy said. “And if there’s something he doesn’t do well, he’s going to want to do well at it, and he’s going to design something that can help him do it.”
Chapman himself has emphasized staying healthy as his primary focus at this stage of his career. The veteran closer has expressed pride in his durability and commitment to the daily work required to pitch at a high level in his late 30s, viewing the opportunity to remain on the field as central to his continued success with Boston.
