Max Scherzer targeting early-to-mid June return after bullpen session, per Sportsnet

What happened

Max Scherzer threw around 30 pitches in a bullpen session, a meaningful step toward the mound for a pitcher who has been on the 15-day injured list for approximately a month. Arden Zwelling of Sportsnet reported the session, noting that the Blue Jays are weighing either another bullpen outing or a live-hitter session as the next progression, with a rehab assignment expected to follow. MLB.com's injury tracker places Scherzer's return in the early-to-mid June range, though the later end of that window could be realistic given the nature of the recovery.

The injuries keeping him sidelined are a combination of right forearm tendinitis and left ankle inflammation — two separate issues that have kept the 41-year-old from building any kind of rhythm since his season began in late March.

Why it matters

Rotation depth is not a decorative concern in May. It is the thing that separates a team managing a pennant race from one managing a phone tree of emergency starters. Per MLB Trade Rumors, Scherzer is expected to be a key piece of that depth when he returns, which means Toronto has a genuine interest in getting the progression right rather than rushing it.

The 15-day IL is the standard placement for pitchers under league rules, and a rehab assignment — which can run up to 30 days for pitchers before a decision must be made — gives the club a structured way to rebuild his workload before any activation. None of that has been announced as the current plan; it reflects the general mechanics available to the organization as Scherzer moves through his recovery.

What makes the situation worth watching closely is the nature of the pre-IL sample. The five starts Scherzer made before landing on the injured list were, as MLB Trade Rumors described them, a mixed bag — and that framing is doing some work.

The numbers

The split across those five starts is worth sitting with. In his season debut on March 31st, Scherzer allowed one earned run across six innings. He followed that on April 18th with two earned runs in another six innings — two outings that looked, on the surface, like a veteran finding his footing. The other three starts, however, did not reach the three-inning mark, whether due to injury or ineffectiveness, per MLB Trade Rumors. That is the full picture the Blue Jays are working from: two encouraging outings bookended by three abbreviated ones, and then a month on the shelf.

There is no clean way to read a five-start sample that includes injury-shortened appearances as a reliable signal of what Scherzer is or is not at this stage of his career. The bullpen session — approximately 30 pitches — is the first new data point in roughly a month, and it is a process marker, not a performance verdict.

Where the club stands

No standings data is on file for this story, so the precise shape of Toronto's rotation picture cannot be drawn here with numbers. What MLB Trade Rumors does establish is the operational context: the Blue Jays have a pitcher they consider important to their rotation depth who has not thrown a competitive inning in approximately a month, and who is now working through a multi-step return process with an early-to-mid June target.

For a team navigating a long season, the difference between Scherzer returning in the first week of June and the third week of June is not trivial. A rehab assignment adds time but also adds competitive innings — the kind that tell a coaching staff whether the forearm and ankle are holding up under real conditions, not just bullpen structure.

What we don't know yet

The Blue Jays have not announced whether the next step will be another bullpen session or a live-hitter appearance — Zwelling reported that both are under consideration. The timing of a rehab assignment has not been specified. And the return date, while framed as early- to mid-June per MLB.com's injury tracker, carries the explicit caveat that the later end of the window may be more realistic.

MLB Trade Rumors also does not specify which of the two injuries — the right forearm tendinitis or the left ankle inflammation — is the more limiting factor at this point, or whether both are being managed in parallel. That distinction matters for how the progression is structured, but it has not been reported.

What the 30-pitch bullpen session does not answer, and cannot answer, is whether Scherzer's pre-IL results reflected the injuries accumulating or something else entirely. That question will only get addressed once he is pitching in competitive situations again, which is precisely what the rehab assignment is designed to provide.

What to watch

The next step in the progression is the immediate thing to monitor. Per Zwelling's report, the Blue Jays will decide between another bullpen session and a live-hitter appearance before moving to a rehab assignment. The sequencing matters: a live-hitter session introduces game-condition stress that a bullpen session does not, and how Scherzer responds to that step will likely shape how quickly the club moves toward activating him.

Once a rehab assignment begins, the workload and inning counts will be the signal. Under general league mechanics, pitchers have up to 30 days on a rehab assignment before the club must make a decision — activate, transfer to the 60-day IL, or another path. That window gives Toronto flexibility, but it also means the early-to-mid June target is a working estimate that the next few weeks will either support or revise.

For a rotation that has been carrying Scherzer's absence for roughly a month, the question is less whether he returns and more what he looks like when he does. Two of his five starts this year suggested a pitcher who could still eat innings effectively. Three of them did not get past the third. The bullpen session is step one of finding out which version shows up in June.
