MLBTR’s team-by-team look at the upcoming deadline continues with the Red Sox. There has been a lot of drama in Boston this year and it hasn't always been smooth sailing. However, a ten-game win streak just before the break has catapulted them into buyer position. The question now is how aggressive they will be in adding to the club ahead of the deadline. With a glut of outfielders, would they be willing to use that surplus to bolster another area of the roster?
Record: 53-45 (55.9% playoff probability, per FanGraphs)

Potential needs: pitching, first base, backup catcher
The Sox have one elite pillar in their rotation, but it's questionable after that. Even that pillar comes with some degree of uncertainty. Garrett Crochet leads the club in starts and innings pitched, by a healthy margin in both cases. He has a 2.23 earned run average over 129 1/3 innings pitched.
Can he keep it up the rest of the way? In the early parts of his career, he was either hurt or working as a reliever. A move to the rotation last year worked out brilliantly, though the White Sox backed off his workload in the second half. He had 101 1/3 innings pitched through the end of June but then just 44 2/3 innings the rest of the way, finishing at 146 frames. Whether he can get that into the 200 range and still be effective in the postseason is something of an open question.
Even with Boston counting on Crochet to fill one playoff rotation spot, they would need more. Are Lucas Giolito and Brayan Bello viable candidates? Giolito has been trending in a positive direction lately. He missed all of 2024 due to elbow surgery and then a hamstring strain put him on the shelf for the first month of 2025. Through his first seven starts, he had a 6.42 ERA, 18% strikeout rate and 7.3% walk rate. In his most recent six outings: 0.70 ERA, 25.5% strikeout rate and 6.9% walk rate.
The Sox will have to decide if that's small sample noise or Giolito getting on track after years of struggles. From 2019 to 2021, he posted a 3.47 ERA with a 30.7% strikeout rate. But over 2022 and 2023, he had a 4.89 ERA and 25.5% strikeout rate. It would be great if he's back to his old self, but six starts is still a pretty small sample size.
It's a somewhat similar situation for Bello, who missed the first few weeks of the season due to a shoulder strain. Through eight starts, he had a 3.83 ERA, 16.1% strikeout rate and 12.2% walk rate. But in his seven most recent appearances, he has a 2.61 ERA, 19.7% strikeout rate and 5.8% walk rate.
The options beyond those three are not inspiring. Walker Buehler has a 6.12 ERA on the year. Tanner Houck had an 8.04 ERA before a flexor pronator strain sent him to the injured list. Richard Fitts has some passable numbers but just 12 big league starts under his belt. Hunter Dobbins and Kutter Crawford are done for the year. Kyle Harrison isn't doing especially well in the minors. Patrick Sandoval could be a factor later in the season, but he's still a question mark for now. He had UCL surgery just over a year ago and has yet to begin a rehab assignment.
