Don’t Expect a Splash—and That’s Okay
Jeff Passan reported Boston isn’t chasing top-tier deadline deals. That’s not a negative—it’s a smart hedge. With Marcelo Mayer and Roman Anthony already contributing, and Trevor Story and Alex Bregman healthy, there’s no need to overreach.
Craig Breslow’s approach is straightforward: Buy low, stay competitive, and protect 2026 and beyond.

The Turnaround Changed Everything
On July 1, the Boston Red Sox were under .500, looking like a soft-sell candidate. Fast forward four weeks, and they’re 16-7 in July, riding a 10-game win streak into the All-Star break. Now at 58-51, the Sox sit third in the AL East and hold a Wild Card spot by 1.5 games. That surge has reshaped the front office's mindset from “offload” to “opportunistic buyers.”

Devers Trade Wasn’t a Sell-Off—It Was a Reset
Boston's biggest move already happened: shipping Rafael Devers to the San Francisco Giants for Kyle Harrison, Jordan Hicks, Jose Bello, and outfield prospect James Tibbs III. It looked like a teardown at first, but now appears to be a calculated retool. All four pieces fill roster gaps, and Devers’ absence has unlocked playing time for top prospects—most notably Roman Anthony.

Duran Is Off the Table—and That Changes Everything
Jarren Duran has gone from trade chip to franchise cornerstone. Boston turned down the San Diego Padres' offer of Dylan Cease, Ethan Salas, and a third piece. That’s how much they value Duran’s speed, defense, and leadoff spark. With Ceddanne Rafaela now covering the infield and Duran anchoring center, moving him would rip a hole the roster can’t fill in-season. He’s staying put.

Prospects Are Already Producing
Boston’s youth movement is in full swing. Roman Anthony is getting everyday run in the outfield, Marcelo Mayer—out with a wrist injury—is waiting in the wings, and Kristian Campbell saw big league action early. Add in Rafaela’s defensive flexibility and Anthony’s upside, and the Red Sox have already infused fresh legs into the roster. The deadline isn’t about splash—it’s about support.
Deadline Needs: Targeted and Tactical
Despite the hot streak, holes remain:
Rotation depth is shaky. ERA’s north of 4.00 with Walker Buehler struggling and multiple arms shelved.
Lefty bat is needed. Boston ranks 15th in OPS vs RHP (.743) and needs someone to offset the Triston Casas injury.
Backup catcher behind Connor Wong could stabilize the position.
Middle relief help wouldn’t hurt, even with a bullpen ERA of 3.33 (4th in MLB).
Expect small to medium-sized deals here—not blockbusters.
Rotation Targets: Short-Term Rentals & Control Arms
Boston has kicked the tires on several arms:
Mitch Keller (PIT): Under team control through 2028; high cost, but high upside.
Sandy Alcantara (MIA): Wild ERA (6.66) masks solid FIP and stuff. Change-of-scenery bounce-back?
Luis Severino (ATH): On a one-year deal; serviceable ERA and playoff experience.
Nick Martinez, Adrian Houser, Aaron Civale: Value depth adds for the back end.
The Sox don’t need an ace—just a stabilizer.
Lefty Bat Options: Plug the Casas Hole
Triston Casas’ season-ending injury in early May left a gaping hole at first. Here’s who’s in play:
Ryan O’Hearn (BAL): Great fit—but comes with an intra-division tax.
Josh Bell & Nathaniel Lowe (WAS): Two switch-hitting corner options from a bottom-tier team.
Carlos Santana (CLE): Veteran thump with postseason experience.
Boston’s platoon of Abraham Toro and Romy Gonzalez isn’t cutting it. A lefty stick could provide real impact.
Catcher & Bullpen Depth: Quiet Additions Could Pay Off
Travis d’Arnaud (LAA): Veteran backup with postseason reps, could handle a staff down the stretch.
Boston's bullpen is elite, but depth never hurts. Think controllable, middle-relief arms on the cheap.
