Garrett Crochet reaches mound milestone in early step toward Red Sox return

What happened

Garrett Crochet has stepped back on a mound for the first time since his injury, MLB.com reported, marking an early milestone in what Boston hopes becomes a return to the Red Sox rotation. The left-hander had been working back from shoulder inflammation and a lat strain — a combination that had kept him off a mound entirely until this session.

The development follows a bullpen session that, per Posterior Wire reporting from earlier this week, was itself described as Crochet's first bullpen work during the recovery. The mound session reported by MLB.com represents the next rung on that ladder. MLB.com's report also noted that two other Red Sox pitchers are progressing well in their own respective returns, though the headline development belongs to Crochet.

Why it matters

Crochet is not a depth piece. He is the kind of arm that changes what a pitching staff looks like in October, and the Red Sox are very much in an October conversation. Getting him back — in any capacity — would meaningfully alter Boston's options down the stretch and into the postseason.

Posterior Wire reporting from earlier this week noted that his return was expected to come as a reliever rather than a starter, which would represent a role adjustment from his rotation work earlier in the season. That framing is worth holding onto: a starter returning as a high-leverage reliever is a different kind of asset than a starter returning to the rotation, and the operational calculus around roster construction shifts accordingly. None of that is settled yet, but the mound session at least puts the conversation back on the table.

The broader injury picture in Boston adds context. Ceddanne Rafaela is currently sidelined with a right quad injury, with no timetable for return reported. Adley Rutschman, who came over from Baltimore at the trade deadline, returned to the Red Sox lineup after an elbow injury earlier this week, per Posterior Wire reporting. The roster has been absorbing a fair amount of turbulence, and Crochet's mound session is one of the few arrows pointing in a favorable direction.

The numbers

Boston enters the weekend at 77-65 (.542), sitting third in the AL East, 7.5 games back of the division lead. The Wild Card picture is more hospitable: the Red Sox rank second in the Wild Card standings, sitting +5.0 relative to the cut line. They have won two straight.

That Wild Card cushion is meaningful but not comfortable. Five games of separation from the cut line in early September is a position worth protecting, not coasting on. The schedule ahead — three games at Oriole Park at Camden Yards against Baltimore — will test the rotation directly. Friday's probable is Ranger Suarez against Shane Baz. Saturday sends Sonny Gray to the mound opposite Chris Bassitt. Sunday features Payton Tolle against Kyle Bradish.

Where the club stands

Third place in the AL East, 7.5 back, with a two-game winning streak and a Wild Card position that currently reads as a genuine asset. The Red Sox are not chasing the division — that math is steep — but they are in a strong position to hold their Wild Card footing if the rotation stays functional and the injury list stops growing.

The Baltimore series is a reasonable stress test. The Orioles are a familiar opponent at the moment, given that Rutschman made his return to Camden Yards just days ago after the trade-deadline move that brought him to Boston, per Posterior Wire reporting. The pitching matchups across the three games will tell a cleaner story about where this staff actually stands heading into the final weeks of the regular season.

September also brings the expanded roster window — the active roster grows to 28 players from September 1 through the end of the regular season under general league rules — which gives Boston more flexibility to carry arms in various stages of return without immediately forcing difficult roster decisions. That mechanical room matters when multiple pitchers are working back from injury at the same time.

What we don't know yet

A mound session is an early step, not a timetable. MLB.com's report does not attach a return date, a target workload, or a specific role to Crochet's progression. The earlier Posterior reporting suggested a return as a reliever rather than a starter, but that framing carried its own uncertainty and has not been updated by the latest news.

The status of the other two pitchers MLB.com noted as progressing well is similarly unresolved. "Progressing well" is the kind of phrase that can mean many things across a wide range of timelines, and no specifics on workload, next steps, or projected return windows were included in the report.

Rafaela's quad injury remains without a timetable. Kristian Campbell, who signed a $60M deal, is currently in Triple-A working to rediscover his swing after his Driveline-based approach stopped producing, per earlier Posterior Wire reporting — another variable the club is managing alongside the pitching returns.

What to watch

The most immediate question is whether Crochet's mound work continues without setback. A first session off a mound after shoulder inflammation and a lat strain is encouraging; the sessions that follow will tell you whether the body is actually ready to ramp up or whether this is a slower process than the early milestone suggests.

Watch also for any update on the reliever-versus-starter question. If Boston is targeting Crochet for high-leverage relief work down the stretch, the roster construction implications are different than if they are building him back toward a rotation spot. That distinction will shape how the club manages its 28-man roster through September.

The Baltimore series itself is worth monitoring for what it reveals about the current rotation depth. With Suarez, Gray, and Tolle lined up across the three games, the club is leaning on a mix of veterans and younger arms. How those matchups play out will inform how urgently Boston needs Crochet back in the fold before the calendar runs out.
