Craig Breslow has made his biggest offseason wins in the trade market, and that’s where the Red Sox are likely to keep shopping.
Free agency hasn’t been empty for Boston - Alex Bregman was awesome in 2025 and Ranger Suarez was everything the Red Sox could’ve hoped for in 2026 - but the roster that’s back to contender status, at least on paper, has been built heavily through deals. Garrett Crochet, Willson Contreras, Sonny Gray, Caleb Durbin, Adley Rutschman, Eli White, Curtis Mead and Jake Bennett are all part of that trade-driven core.
So with the free agent class looking weak, Boston shouldn’t rule much out this winter. The Red Sox need more power, maybe a starting pitcher if Gray departs, and bullpen help wouldn’t hurt even after they had the best bullpen in baseball in 2026.
Here are the trade options worth watching, ranked from the cheapest fits to the most expensive swings.
Mark Vientos sits near the low end of the cost spectrum, and the appeal is obvious. His 2026 season was rough - 87 games, a .212/.258/.394 line, 13 home runs, 41 RBIs and 28 runs scored - but the power is real.
Back in 2024, he popped 27 homers and drove in 71 runs in 111 games. If the Mets are willing to listen and Boston opens up the designated hitter spot, Vientos looks like the kind of buy-low target the Red Sox could actually land without blowing up the market.
If Gray exits and Boston decides it wants another right-handed starter, Spencer Strider is the kind of name that forces a team to at least make the call. The Braves held onto him at the trade deadline last summer, but he’s still viewed as an ace-type arm. Injuries have knocked his career off course, and that history should keep the asking price down some, even with the deal he already has in place.
Another starter Boston has already checked on is Joe Ryan. Red Sox fans will remember that the club reportedly pushed for him before the 2025 trade deadline and couldn’t close the deal. He’s down to just one year of control now, and that alone should make him more reachable than what the Twins were asking in 2025.
At shortstop, the Red Sox have already been linked to several names, and one that came up this past summer was Anthony Volpe. If Boston isn’t sold on Trevor Story or Franklin Arias, Volpe would be worth circling again as an intriguing middle-infield option.
Then there’s CJ Abrams, who might be the best fit of the bunch if Boston wants to really upgrade the middle infield. Washington was talked about as a possible seller, but the Nationals kept him.
Abrams, who is only 26, put together a monster 2026 season with 33 home runs and 106 RBIs. That kind of bat would change the shape of the lineup, but he’d come at a massive cost.
Now we get into the dream-scenario names.
Ronald Acuna Jr. has been floated because the Braves were knocked out early and speculation started to swirl about whether he could be available. If Atlanta actually made him available, it would take a ransom to pry him away. Still, he’s exactly the sort of player a team pays whatever it takes to get.
Bryce Harper belongs in that same tier. Acuna has two seasons of control left; Harper has five years remaining on his deal and a no-trade clause. There have been rumblings about Harper, and if the Phillies ever did listen, Boston should be at the front of the line.

Red Sox Offseason Urgency Just Got Tied To One Big Bat
The Red Sox are already facing an offseason that feels pointed toward offense, and Randy Arozarena has quickly emerged as a name that fits the conversation. Boston is being linked to the free-agent outfielder as a potential way to add impact to a lineup that could use more thump, and his recent season with the Mariners only adds to the appeal.
Arozarena brings the kind of all-around presence that can change how a batting order is viewed, thanks to a campaign that included 26 home runs and 26 stolen bases. For a Red Sox team looking for a meaningful offensive upgrade, the question now is whether the fit is real enough to turn interest into a deal. [Read more 🡒]
Aroldis Chapman Gave The Red Sox Something They Couldn't Afford To Lose
Aroldis Chapman gave the Red Sox exactly the kind of late-inning certainty they were hoping for when they brought him back as their closer. The veteran left-hander delivered a strong 2026 season, piling up 35 saves with a 1.92 ERA, earning a second All-Star nod as a Red Sox player and reaching the rare benchmark of 400 career saves along the way.
For a bullpen that can never really have too much stability, Chapmans return matters well beyond the individual numbers. Boston and Chapman mutually opted into a $13 million contract option for 2027, keeping one of the games most experienced finishers in place and giving the Red Sox a familiar answer at the end of games as they try to build on what he just provided.

Red Sox Face One Huge Adley Rutschman Decision This Offseason
The Red Soxs offseason arrived fast after their wild-card loss to the Yankees, and now the front office has a defining choice to make as it shapes the next roster. A central part of that conversation is catcher Adley Rutschman, who has one year of control left and already looms as one of the biggest decisions on Bostons winter checklist.
Chief baseball officer Craig Breslow recently praised Rutschmans leadership but stopped short of saying where extension talks stand, leaving the picture murky as the club weighs bigger 2027 questions across the roster. Boston is also sorting through trade possibilities and pitching-staff decisions, but the Rutschman situation may end up telling the clearest story about how aggressively the Red Sox want to push their timeline.
