Aroldis Chapman etched his name into baseball history Sunday afternoon, becoming the ninth pitcher ever to record 400 career saves as the Boston Red Sox completed a four-game sweep of the Baltimore Orioles with a 3-1 victory at Camden Yards.

The 38-year-old closer sealed the milestone by striking out Christian Encarnacion-Strand on a 101-mph heater. Chapman worked around a one-out Pete Alonso single in the ninth inning before completing No. 400 with his signature fastball.

"Yeah, I think last year with the season that I had, I started thinking about that goal and that number," Chapman said after the game. "I hadn't been [a full-time] closer to that point since 2022. So for me to have that opportunity to close games and to have a good season was the point when I thought that 400 was possible."

Chapman joins an exclusive club that includes Mariano Rivera (652), Trevor Hoffman (601), Kenley Jansen (493), Lee Smith (478), Craig Kimbrel (441), Francisco Rodriguez (437), John Franco (424) and Billy Wagner (422). Of the previous eight members, four are in the Hall of Fame, while two others—Jansen and Kimbrel—remain active.

Redemption Story

The milestone carries extra weight given Chapman's recent struggles. From 2022-24, the Cuban flamethrower managed just 29 saves across four different teams, losing his closer role with the Yankees in mid-May 2022 due to command issues. During that three-year stretch, he served primarily as a setup man, with 14 of those saves coming when he got opportunities to close games for the Pirates late in the 2024 season when David Bednar was struggling.

Chapman's resurgence began when he signed with Boston prior to the 2025 season. He won the closer's job in Spring Training and has been an All-Star in that role for the Red Sox the past two years, rejuvenating his career by attacking the strike zone more aggressively.

"Making it special for Chapman is that this goal didn't feel within reach from 2022-24," according to MLB.com's Ian Browne, who covered the achievement. The veteran closer had to rebuild both his confidence and his command before the milestone became realistic.

Still Throwing Heat

While Chapman doesn't hit 100 mph as frequently as in his prime, he continues to average 98 mph with his sinker and 97 mph with his fastball—remarkable velocity for a pitcher approaching 40. His durability and consistent performance have impressed Red Sox interim manager Chad Tracy.

"We've spoken a lot about him," Tracy said. "It's impressive, doing what he's doing for as long as he's been doing it, and the work he puts in to keep himself in shape and keep himself able to post as much as he does. He's pretty impressive."

The left-hander has embraced a flexible role with Boston, often entering in the eighth inning when the opposing team's best hitters are due up, rather than focusing solely on save situations. This approach has enabled the Red Sox to win games in walk-off fashion or in extras.

"Of course," Chapman said about pitching in various situations. "That's practically [the same] as saving the game. Probably not in the statistics, but you just gave your team an opportunity to win the game, so you have that same mentality, like you're going to close the game. That's the most important thing. Just be ready for any opportunity that the team needs me."

The sweep of Baltimore improved Boston's position as they continue their push toward the postseason. For Chapman, who revolutionized the modern era of triple-digit velocity, the 400-save milestone strengthens his eventual Hall of Fame case while cementing his place among the game's elite closers.

With his signature stare-down after strikeouts and his willingness to pitch in any high-leverage situation, Chapman has found new life in Boston. The 400th save represents not just a career achievement, but a testament to his ability to reinvent himself when his career seemed to be winding down.
