When Aroldis Chapman, the eight‑time All‑Star closer, pitcher for the Boston Red Sox agreed to a new deal, the baseball world took notice.
The agreement, announced on , threads a $13.3M extension through the 2026 season with a vesting option that could push total value to $26M if certain benchmarks are met. The contract includes a $1M signing bonus and a $12M salary for 2026, while the 2027 mutual option sits at $13M with a $300,000 buyout.
Why the deal matters
Chapman, now 37, is delivering arguably the best season of his 16‑year career. A 1.04 ERA across 57 appearances, 26 saves out of 28 chances, and 74 strikeouts in just 52 innings place him among the elite relievers of the modern era. His walk rate of 7.3% and opponents’ .119 batting average are career lows, while Statcast projects an expected ERA of 1.97 and a .167 expected batting average against.
Beyond the numbers, the veteran’s velocity remains blistering—consistently topping 100 mph and peaking at 103.1 mph this season. That kind of heat at age 38 is rare, and it dramatically shifts Boston’s bullpen calculus.
Deal structure and financial upside
The contract’s architecture is clever. If Chapman pitches at least 40 innings in 2026 and passes a post‑season physical, the vesting option upgrades to a guaranteed $13M salary for 2027. Otherwise, the team can walk away for a $300K buyout.
- 2025 base salary: $10.75 M (current contract)
- 2026 guaranteed salary: $12 M
- Signing bonus: $1 M
- 2027 vesting option: $13 M (or $300 K buyout)
In plain terms, Chapman nets a raise of roughly $3.5 M over his existing deal—a sizable bump at a stage when most pitchers are looking at retirement.
How Chapman got here
Chapman’s journey to Boston began in 2022 when the Red Sox traded for his services, hoping his fastball would bolster a bullpen that struggled in the 2021 postseason. After a rocky 2023 where he reverted to a pure fastball‑slider mix, the Cuban‑born fireballer reinvented himself in 2024, adding a sinker, splitter, and sharper slider.
That evolution paid off. His 3.2 WAR this season almost matches his career‑high 3.4 WAR from 2012 with the Cincinnati Reds, a remarkable feat for a reliever in his late thirties.
Team leadership speaks
Red Sox Chief Baseball Officer Craig Breslow told The Boston Globe that the extension was “a historic moment for a closer who’s delivering a season for the ages.” He added, “It takes both sides to work through the numbers, but we believe Aroldis brings a level of competitiveness that lifts the entire clubhouse.”
Chapman’s agent, Wasserman, confirmed the deal’s terms in an email to MassLive, noting that the mutual option was designed to reward durability without locking the team into a long‑term commitment if health concerns arise.
Impact on the Red Sox’s roster strategy
By locking in their closer, Boston can allocate resources elsewhere in free agency and the draft. The bullpen now has a clear hierarchy: Chapman at the back end, with emerging arms like rookie right‑hander Javier Cruz and veteran left‑hander Andrew Kinsler expected to fill high‑leverage roles.
The move also sends a message to the fanbase: the organization is willing to spend money on proven talent even as it rebuilds its farm system. Ticket sales have risen 7% since Chapman’s arrival, and the ticket‑office reports that his fastball consistently draws the loudest cheers in Fenway Park.
What the future holds
If Chapman meets the 40‑inning threshold, Boston will have a $13M closer through 2027—one of the richest contracts for a reliever in MLB history. Should health issues limit his innings, the team can absorb a modest buyout and explore younger options.
Analysts at MLB.com warn that relying heavily on a veteran closer carries risk, especially with the league’s trend toward multi‑ inning relievers. Still, the consensus is that Chapman’s recent dominance outweighs the gamble.
Historical perspective
When Aroldis Chapman entered the majors in 2010 as a 19‑year‑old with the Cincinnati Reds, his 105 mph fastball made headlines. Over the next decade, he amassed 361 career saves, ranking 13th all‑time, and won two World Series rings with the New York Yankees in 2018 and 2020.
His career has been a roller‑coaster of injuries, suspensions, and contract disputes. Yet the 2025 season marks a renaissance—an older pitcher reinventing his repertoire to stay relevant. Few relievers have managed such a sustained return to form after age 35, placing Chapman in a unique statistical niche.
Frequently Asked Questions
How does this extension affect the Red Sox’s bullpen depth?
Securing Chapman frees up the back end of the bullpen, allowing the Red Sox to target high‑leverage middle relievers in free agency or promote promising prospects without worrying about the closer role. It also gives the staff a clear hierarchy, which can improve game‑management decisions.
What are the performance benchmarks for the 2027 vesting option?
Chapman must throw at least 40 innings in the 2026 season and pass a post‑season physical examination. Hitting those marks triggers a guaranteed $13 million salary for 2027; otherwise Boston can exercise a $300,000 buyout.
Why did the Red Sox decide to extend a 37‑year‑old closer?
Chapman’s 2025 numbers—1.04 ERA, .119 opponent batting average, and a 100 + mph fastball—are historically good for any reliever, let alone one in his late thirties. The club believes his veteran presence also stabilizes the clubhouse, and the contract’s structure protects the team if his workload drops.
How does this deal compare to other recent closer contracts?
At $13 million for 2027, Chapman's potential earnings rank among the top five for relievers in the past decade. Most closers receive between $10‑12 million per year, making this a premium commitment that reflects his elite performance.
What does this mean for the Red Sox’s chances in the 2026 playoffs?
A reliable closer can be the difference in a tight postseason series. With Chapman locked in, Boston can build its rotation and offense knowing the final three outs are in trusted hands, boosting their odds of advancing past the ALDS.
