Trey Yesavage expected to start Monday vs. Orioles in return from knee IL

Trey Yesavage is expected to return from the injured list and start Monday against the Baltimore Orioles, per Arden Zwelling of Sportsnet, as relayed by MLB Trade Rumors' Charlie Wright. The right-hander has been sidelined since early August with right knee inflammation and threw 34 pitches in his lone rehab appearance with Triple-A Buffalo earlier this week. The club has not announced the move.

What happened

Per the report, Yesavage is on track to take the ball Monday at Oriole Park at Camden Yards, where the Blue Jays' probable starter is listed as Yesavage against a yet-to-be-named Baltimore starter. Zwelling adds that Yesavage should be able to cover only a few innings in his return, with swingman Spencer Miles identified as an option to share the workload in what would effectively be a tandem outing.

The cautious inning limit is worth noting. A pitcher returning from a six-week absence after throwing 34 rehab pitches is not walking into a seven-inning audition. The Blue Jays appear to be managing the workload deliberately, which is where Miles enters the picture as a practical complement rather than a fallback.

Why it matters

Toronto is 2.5 games outside the final AL Wild Card spot heading into Saturday night's action, and the schedule is not offering any soft landings. The Blue Jays close out their current road trip with two more games against the Texas Rangers — who sit directly ahead of them in the Wild Card race — before traveling to Baltimore. Every rotation decision between now and the end of the regular season carries playoff implications, and Yesavage's availability, even in a limited capacity, adds a credentialed arm to a staff that has been leaning heavily on bullpen games.

That context matters more when you account for what the rotation has lost. A few days after Jameson Taillon said his 2026 season was over due to an elbow issue — with UCL concerns and a meeting with Dr. Keith Meister in the picture, per prior Posterior reporting — the Blue Jays are piecing together their stretch-run rotation from a shorter list than they would have drawn up in spring. With Dylan Cease, Jose Soriano, and Max Scherzer anchoring the group, the days those three aren't starting have required creative solutions: bullpen games, bulk roles, and now a carefully rationed Yesavage.

Sunday's approach at Globe Life Field, per Zwelling, will feature Spencer Arrighetti in a bulk role against the Rangers. The Blue Jays are also weighing a left-handed opener for Monday's game — a consideration driven by the presence of lefty bats Corey Seager and Brandon Nimmo at the top of Texas's lineup, per the report — which could reshape the tandem structure or push Yesavage's actual work deeper into the outing.

The numbers

Injuries have held Yesavage to 18 starts this season, but the production across those outings has been generally solid. Per the report, he carries a 3.65 ERA across 93 2/3 innings — a workload that reflects both his effectiveness when available and the persistent interruptions that have defined his year.

The strikeout rate sits at 23.6%, a respectable mark. The walk rate, at 11.9%, is the number that draws the raised eyebrow. Control has been a recurring theme with Yesavage: he posted an 11.3% walk rate in the majors last year and a 10.5% mark in the minors, per the report. The 11.9% figure this season suggests that particular challenge has not resolved itself, even as the rest of his profile has held up.

A shoulder issue delayed him to start the year, and the knee inflammation has since cost him six weeks. The 93 2/3 innings represent what was salvageable from a season that kept finding new ways to interrupt itself.

Where the club stands

Toronto sits at 76-78 (.494), 4th in the AL East and 18 games back in the division race — eliminated from that conversation entirely. Their focus is the Wild Card, where they rank 5th at 2.5 games relative to the cut line, currently riding a one-game losing skid after dropping three of four this week.

The upcoming schedule frames the stakes plainly: Saturday at Texas with José Soriano opposing Cal Quantrill, Sunday at Texas with the Blue Jays' starter listed as TBD against Jacob deGrom, and Monday at Baltimore with Yesavage listed against a TBD Orioles starter. Per the report, the Rangers sit directly ahead of Toronto in the Wild Card standings, and the Blue Jays have two more chances against them before shifting to Baltimore. The math is tight, the margin for error is thin, and the next two games are against the team standing between Toronto and the bracket.

What we don't know yet

The club has not announced Yesavage's activation, and the report frames his Monday start as an expectation rather than a certainty. It is also not yet clear whether Toronto will deploy a left-handed opener ahead of him Monday — Zwelling notes it as a possibility the club is considering, not a decision that has been made.

The precise inning split between Yesavage and Miles, should the tandem approach hold, is also unspecified. "A few innings" is the framing in the report, which leaves the actual workload distribution open.

What to watch

The most immediate question is whether Yesavage's knee holds up through his first live game action since early August. A 34-pitch rehab outing is a limited data point, and the Blue Jays' decision to pair him with Miles rather than hand him a conventional start suggests the organization is not treating this as a full return to form — at least not yet.

Worth watching alongside that is how Sunday's Arrighetti bulk outing goes against Texas, and whether the left-handed opener option for Monday gets settled or set aside. The Rangers series is the more pressing competitive test; Baltimore is the stage where Yesavage is reportedly set to re-enter. How those two days unfold will shape what Toronto asks of him — and how much runway they're willing to extend — as the calendar runs short.
