Shohei Ohtani's Sunday start uncertain as Dodgers monitor bullpen session

The Dodgers have not yet decided whether Shohei Ohtani will pitch Sunday afternoon in Detroit, manager Dave Roberts said Friday night, per Jon Morosi of MLB Network. The club is waiting to see how Ohtani feels Saturday after throwing a 20-pitch bullpen session Friday. Tyler Glasnow is scheduled to pitch Sunday in any case; the question is whether Ohtani would take the mound ahead of him.

What happened

Roberts told reporters Friday that the starting pitcher for Sunday's series finale against the Tigers remains to be determined, Morosi reported. The decision hinges on how Ohtani responds Saturday to the 20-pitch bullpen he threw a day earlier. Glasnow is scheduled to pitch at some point Sunday regardless of Ohtani's availability, leaving open the possibility of a tandem start or a traditional Glasnow outing if Ohtani is held back.

The Dodgers are scheduled to face Framber Valdez on Sunday at Comerica Park. Blake Snell is slated to start Saturday against Keider Montero.

Why it matters

The uncertainty around Ohtani's next start introduces a wrinkle into the Dodgers' rotation planning as they enter the final month of the regular season. Ohtani has been a fixture in the Los Angeles rotation since returning to the mound this year, and any deviation from his usual schedule invites questions about his health and workload management. The 20-pitch bullpen session suggests the club is monitoring something—whether fatigue, soreness, or simple caution—but Roberts did not specify what prompted the between-starts session or what the Dodgers are watching for Saturday.

The tandem-start possibility, with Ohtani opening and Glasnow following, would be an unusual deployment for two front-line starters. It could reflect a desire to limit Ohtani's workload while keeping him in rhythm, or it could be a contingency plan if the club determines he is not ready for a full outing. The Dodgers have not publicly disclosed an injury or ailment, and the framing—waiting to see how he feels—leaves the situation open to interpretation.

Roberts' decision to keep Sunday's starter undecided this late in the week is itself noteworthy. Clubs typically announce probable pitchers days in advance, and the Dodgers had already listed Glasnow for Sunday before Roberts' comments Friday night. The shift to "to be determined" signals that something changed or emerged recently enough to warrant the extra day of evaluation.

The numbers

Ohtani has been one of the most durable and effective pitchers in baseball this season, though his exact statistics were not included in the material available. His presence in the rotation has been a cornerstone of the Dodgers' success, and any adjustment to his schedule carries weight both for the club's immediate plans and for how they manage his workload heading into October.

Glasnow, meanwhile, has been a key addition to the rotation since joining the Dodgers. His scheduled appearance Sunday, whether as a traditional starter or in tandem with Ohtani, ensures the club will have one of its top arms on the mound against Valdez and the Tigers.

Where the club stands

The Dodgers entered Saturday with an 85-57 record, leading the National League West by a comfortable margin and carrying a three-game winning streak. Their division magic number stands at 10, meaning any combination of 10 Los Angeles wins or second-place losses clinches the division. The club is on pace for one of the best records in baseball, and the rotation depth that includes Ohtani, Glasnow, and Snell has been central to that success.

That cushion affords the Dodgers the luxury of caution. With the division all but wrapped up and the postseason looming, the club can prioritize long-term health over short-term necessity. If the 20-pitch bullpen session was precautionary, the Dodgers have the record to support an extra day of rest or a modified workload without jeopardizing their playoff seeding.

After Sunday's game in Detroit, the Dodgers return home to UNIQLO Field at Dodger Stadium for a Tuesday series opener against the St. Louis Cardinals. Eric Lauer is scheduled to start that game opposite Michael McGreevy. The homestand marks the beginning of September, when active rosters expand from 26 to 28 players, giving clubs additional flexibility to manage workloads and rest key contributors down the stretch.

What we don't know yet

The Dodgers have not said what prompted the Friday bullpen session or what specific concern they are monitoring. Roberts' comments, as reported, did not include a diagnosis, a timeline, or a description of discomfort. The club has not ruled Ohtani out for Sunday, but it has not committed to him pitching, either. Whether the 20-pitch session was precautionary, part of a planned adjustment to his routine, or a response to something Ohtani reported is not yet clear.

It is also unclear how the Dodgers would structure Sunday's game if Ohtani does pitch. A traditional outing would have him work deep into the game, with Glasnow available in relief or held for a later start. A tandem arrangement would likely see Ohtani work a limited number of innings before handing the ball to Glasnow, a setup more common in the postseason or in rehab contexts than in late August with a healthy roster.

The absence of detail leaves room for interpretation. A 20-pitch bullpen is not an unusual workload for a starting pitcher between starts, but the fact that the Dodgers are waiting to see how Ohtani feels afterward suggests the session was not routine. Whether that reflects a minor issue the club is managing conservatively or something more significant will become clearer once Roberts makes his decision.

What to watch

The Dodgers will make a decision after observing Ohtani on Saturday, which means clarity should arrive before Sunday's first pitch. If Ohtani pitches, the length of his outing and the way the club deploys Glasnow will offer clues about whether this was a minor precaution or something that required a more conservative approach. If Ohtani does not pitch, the next question becomes when he will take the mound next and whether the Dodgers adjust his schedule for the remainder of the regular season.

The timing is notable. September 1 marks the expansion of active rosters from 26 to 28 players, giving clubs additional flexibility to manage workloads and rest key contributors down the stretch. The Dodgers' division lead affords them the luxury of caution, but Ohtani's role as both a rotation anchor and a daily presence in the lineup makes any deviation from routine worth tracking. How he feels Saturday, and what Roberts decides Sunday morning, will clarify whether this was a minor adjustment or the start of a longer conversation about his workload as October approaches.

The Dodgers have been careful with their pitching staff all season, and the decision to leave Sunday's starter undecided reflects that same caution. Whether Ohtani pitches, and how the club structures the game if he does, will be the first indication of how they plan to navigate the final month with their rotation intact and their division lead secure.
