Garrett Crochet diagnosed with low-grade lat strain, return timeline unclear

What happened

An MRI taken over the weekend on Garrett Crochet came back with a diagnosis of a low-grade lat strain, according to Red Sox interim manager Chad Tracy, who spoke to the Boston beat following Tuesday night's loss to Baltimore. Christopher Smith of MassLive relayed Tracy's comments. Crochet had reported lingering shoulder tightness over the weekend, which prompted the imaging. Tracy characterized the result in terms that suggest relative encouragement given the circumstances — a low-grade strain rather than something more severe — though the left-hander's return to action will be delayed regardless. Per the report, Crochet will not resume a throwing program until he is fully asymptomatic.

No timetable has been attached to that condition. "Asymptomatic" is the only clock that matters right now, and it is not one anyone can set in advance.

Why it matters

Crochet is not just any rotation piece. Last year's AL Cy Young runner-up and a two-time All-Star, he arrived in Boston carrying the kind of expectations that get stitched into a fanbase's nervous system fairly quickly. The lat strain diagnosis adds a new layer to what has already been a difficult season — he has been out of action since April 26 due to shoulder inflammation, and the imaging this weekend revealed that the shoulder tightness he reported was connected to a lat issue rather than resolving cleanly.

The practical consequence is that Boston's rotation is navigating a meaningful stretch of the schedule without its marquee arm, and the club has no announced date to plan around for his return. Per the report, Crochet has been on the 15-day injured list, the standard placement for pitchers under general league rules. He is also described as a candidate for a 60-day IL transfer should the Red Sox need to free up a 40-man roster spot. Under general roster mechanics, a 60-day IL placement removes a player from the 40-man count entirely, which can give a front office meaningful flexibility. Per the report, any such transfer would backdate to Crochet's original IL date, meaning 38 days have already elapsed against that clock.

That backdating detail is worth sitting with. A 60-day IL move, if the Sox were to make it, would not reset the calendar from scratch. The structural option exists and the report flags it explicitly — as a possibility contingent on roster needs, not as a decision that has been made.

The numbers

Crochet has been limited to six starts this season, carrying a 6.30 ERA. Per the report, the bulk of that figure traces to a single rough outing against the Twins on April 13 — context that matters considerably when reading the ERA in isolation. Six starts is a thin sample under any circumstances, and one catastrophic line can distort a rate stat when the denominator is that small. The number is real; what it represents about Crochet as a pitcher is a murkier question.

The Red Sox enter Wednesday sitting at 87-75 (.537), third in the AL East, 11 games back in the division. They rank second in the Wild Card picture, sitting +3.0 relative to the cut line. That Wild Card position is the number that gives the Crochet situation its operational urgency. Boston is not playing for seeding from a comfortable lead; they are holding a position that requires them to keep winning, and they are doing it without the pitcher who was supposed to anchor the staff.

Where the club stands

### Is Crochet pitching this week?

No. Per the report, he must be asymptomatic before he can resume a throwing program, and no timetable has been provided. He will not factor into Boston's immediate rotation plans.

The Red Sox are on a one-game losing streak following Tuesday's loss to Baltimore. Their next three games continue that same series: Wednesday at Fenway Park features Payton Tolle against Chris Bassitt, Thursday brings Brayan Bello against Trevor Rogers, and the club then travels to Yankee Stadium on Friday, where Sonny Gray is the probable starter against Ryan Weathers.

That is a rotation being asked to hold a Wild Card position +3.0 relative to the cut line without Crochet, against Baltimore — a division rival — and then the Yankees. The schedule does not offer a soft landing while the front office waits for an asymptomatic update.

The 40-man roster question is also live. If Boston needs a spot — for a call-up, a transaction, or any other purpose — the 60-day IL transfer is reportedly available as a mechanism. It would not affect Crochet's recovery timeline; it is an administrative tool, not a medical one. But it would signal that the front office does not expect him back in the near term, which carries a different implication than a 15-day IL placement alone. Per the report, the club is described as eliminated from the division race, which means every decision between now and the end of the regular season is being made in a Wild Card frame.

What we don't know yet

The report does not specify when Crochet might become asymptomatic, what the expected recovery arc looks like in his particular case, or whether the club has any internal target date. Tracy's framing — resume throwing once asymptomatic — is the entirety of the public timeline. There is also no indication in the report of whether the shoulder inflammation that kept him out since April 26 and the lat strain are being treated as related or separate issues, beyond the fact that the MRI this weekend followed a report of lingering shoulder tightness.

Whether a 60-day IL transfer actually happens is also unresolved. Per the report, it is described as a possibility contingent on roster needs, not a decision the organization has made.

What to watch

The first marker is straightforward: any update from the Red Sox on Crochet's symptoms. Tracy's condition — asymptomatic before throwing resumes — means the next meaningful development is either an encouraging update on how he is feeling or a longer silence that implies the lat strain is taking its time. Christopher Smith of MassLive has been the conduit for this one, and the beat will be the place to watch for movement.

The second thing to watch is the 40-man roster. If Boston makes a move that requires a spot and Crochet is transferred to the 60-day IL, that would be a concrete signal about how the front office is reading his availability. It would not change his medical situation, but it would tell you something about how the organization is planning around it — and with 38 days already elapsed against that backdated clock, the math on a potential transfer is not abstract.

The third, quieter thing to watch is how the rotation holds. Bello, Gray, Tolle, and the rest of the staff are carrying a Wild Card position that sits +3.0 relative to the cut line. That is a real cushion, but it is not an infinite one, and the schedule ahead includes the Yankees. The Red Sox are, for now, a playoff-positioned team running their rotation without last year's AL Cy Young runner-up, and the lat strain diagnosis means that is not changing soon.
