Why Aroldis Chapman Is the Most Wanted Reliever on the MLB Trade Block

Aroldis Chapman is 38 years old. He is also the most wanted reliever in baseball, and the Boston Red Sox are about to cash in.
Chapman has been the closer in Boston for the second year and has been historically dominant. He has converted 28 consecutive save opportunities. He has a 0.46 ERA, a 0.92 WHIP, and 17 saves in 19.2 innings. He is the top relief option on every contender’s trade deadline target list.
The Red Sox are unlikely to be playoff contenders this year. They are 36-38 and 7 games out of the wild card. With Rafael Devers gone in the trade last summer, the team has been rebuilding around prospects and waiting for the Roman Anthony era to begin. Trading Chapman at the deadline is the obvious move.
The market for elite relievers has gotten insane over the last few years. The Padres traded for Mason Miller last summer and gave up two top-100 prospects. The Phillies dealt for David Bednar in 2024 and surrendered their top pitching prospect. Chapman is going to command the same kind of return because he is even better than those names.
The veteran left-hander has been throwing harder than ever, which is the kind of sentence nobody expected to write in 2026. His average fastball velocity is 99.3 mph, the highest of any pitcher in baseball. He has touched 102 mph in multiple appearances this year. The reinvention story has been one of the most compelling individual narratives in MLB.
The Yankees are the obvious frontrunner. Chapman pitched for them from 2016 to 2019 and won a World Series with them in 2009 with the Marlins. He remains one of the most iconic Yankees relievers of the last two decades. The pinstripes are short on bullpen help, and Chapman could close out games in October with the kind of dominance the team has been missing since Mariano Rivera retired.
The Yankees also have the prospect capital to make the deal work. They have a deep system anchored by 2024 first-rounder Cam Smith, plus multiple top-100 pitchers in their system. The Red Sox would extract a real cost, but New York has the assets.
The Mets are also in the conversation. They have been spending freely under owner Steve Cohen, and adding Chapman to a bullpen that includes Edwin Diaz would create the most dominant late-inning combination in the league. The Mets also have the prospect depth to match what Boston is asking.
The Phillies are circling too. They lost to the Dodgers in the NLDS last year in a series where their bullpen melted down. Adding Chapman would solve that problem and give them the closer they have been lacking since Craig Kimbrel left.
The complication for Boston is the financial side. Chapman is signed for $10.75 million this year on a one-year deal with no options. Any acquiring team takes him as a rental, which limits what they will give up. The deal becomes essentially a two-month commitment for the contending team.
Still, the market is what it is. The Red Sox should be able to extract a top-100 prospect and a B-level prospect for Chapman, which is more than enough to justify the trade. Craig Breslow, the Boston chief baseball officer, has been working the phones for weeks.
The Red Sox have other pieces to trade too. Lucas Giolito is having a bounce-back year and could fetch a good return. Justin Slaten has been a useful setup man and would also have a market. Boston has the chance to add three or four real prospects through trade deadline maneuvering.
For Chapman personally, the trade decision is more interesting than people realize. He has full no-trade rights as a player with 10 years in the league and five years with one team. Technically he does. Practically the move makes sense because he wants another World Series ring, and Boston is not getting there this year.
The expected destination is the Yankees. The familiarity, the location, and the chance to chase October memories all point to a return to the Bronx. The trade would happen with about an hour to go before the July 31 deadline if history is any guide.
Aroldis Chapman in pinstripes again, closing out games in the World Series. That is the story that has the entire baseball world watching the deadline this year. The clock is ticking. Boston is ready to deal.
