Tarik Skubal working back through sim outings as Tigers stay cautious on return timeline

What happened

Tarik Skubal is throwing simulated game outings as part of his recovery from injury, MLB.com reported, and the Tigers are deliberately keeping their expectations measured when it comes to when he might return for the stretch run. The club is practicing patience — which, in late-season pitching terms, is either a virtue or a very polite way of saying the calendar is doing its own negotiating.

MLB.com described Skubal as bringing intensity to his sim work, while the organization's posture remains cautious about projecting any specific return date.

Why it matters

A starting pitcher working through sim outings occupies a particular kind of roster limbo. He is not on a rehab assignment — which, under general league rules, allows a pitcher up to 30 days before a club must activate him or make another roster decision — and he is not yet back on the active roster. Sim outings are the step before that: live competitive work against hitters, but in a controlled environment, without the clock of a formal rehab assignment running.

For a team managing a stretch run, that distinction matters operationally. A sim outing tells the coaching staff and medical personnel whether a pitcher's stuff is where it needs to be, whether his mechanics are holding up under game-intensity effort, and whether the next step — a formal rehab assignment, a bullpen appearance, or a rotation slot — is realistic. It is the baseball equivalent of a dress rehearsal where the director reserves the right to cancel opening night.

The Tigers' stated caution about the return timeline is worth taking at face value. Clubs sometimes use careful public language to manage expectations; they also sometimes use it because they genuinely do not know yet. MLB.com's framing — that Detroit is practicing patience — suggests the organization is not operating under any internal deadline, and that Skubal's workload will be dictated by how he responds rather than by the standings.

What we don't know yet

MLB.com's report does not specify the nature of Skubal's injury, how long he has been working through this process, or how many sim outings he has completed. There is no timetable attached to his return, no indication of whether a rehab assignment is imminent, and no detail about whether he is being considered for a rotation role, a bullpen role, or simply a return whenever the baseball and the body agree.

This is a credible account from a reliable outlet, but not a formal club announcement with a specific roster transaction attached. The Tigers have not announced a return date, and MLB.com is not reporting one.

It is also worth noting what cautious about his return timeline for the stretch run does not say. It does not say he will not return during the stretch run. It says the club is not committing to that outcome, which is a meaningfully different thing. Sim outings can accelerate. Responses can be encouraging. The door is open; the club is simply not telling anyone how wide.

What to watch

### When does Skubal move to a rehab assignment?

The next concrete step to watch for is whether Skubal transitions from sim outings to a formal rehab assignment. Under general league rules, pitchers on the injured list can be sent on rehab assignments for up to 30 days before the club must make a roster decision. That window is long enough to accommodate a gradual ramp-up through multiple starts at the minor-league level, which is typically how a starting pitcher returning from injury builds back toward a full workload.

If the Tigers announce a rehab assignment, that would signal the organization has cleared an internal threshold of confidence that Skubal is ready for live-game conditions against opposing hitters — a meaningful step beyond the controlled environment of a sim outing. Until that announcement comes, the sim-outing phase continues to serve its diagnostic purpose.

The roster mechanics of a September stretch run add a layer of context here. Under general league rules, active rosters expand from 26 to 28 players beginning September 1, and the 40-man roster remains the pool from which any call-up or activation must come. A pitcher returning from the injured list does not require a roster spot to be cleared in the same way a call-up does, but the club still has to manage its 40-man construction and its active roster shape around whatever role Skubal would fill upon return.

For a rotation, the question is straightforward: does he slot back in, and does someone else move to the bullpen or to the injured list to accommodate him? For a bullpen role — which sometimes serves as a bridge back for starters who are not yet stretched out to full starting length — the roster math is different but no less real. The Tigers have not indicated which scenario they are planning for, and given their stated caution, it is possible they have not decided yet either.

What the sim-outing phase does provide is time. Time for Skubal to build arm strength, time for the medical staff to monitor his response, and time for the front office to watch the standings and decide what kind of contribution, in what kind of role, would be most useful if and when he is ready. That is not indecision — it is the rational use of a process that exists precisely for this situation.

The stretch run has a way of compressing decisions that felt distant in August. Rosters expand, schedules tighten, and the margin for error on pitching decisions narrows. A healthy Skubal, whenever that arrives, would represent a meaningful addition to Detroit's options. The Tigers, for their part, appear content to let the sim outings tell them when that moment is.

MLB.com will be the outlet to watch for any update on his progression, a rehab assignment announcement, or a change in the club's stated posture on his timeline.
