Colin Holderman will not pitch in the postseason. MLB.com reported, per Tim Stebbins, that the Cleveland Guardians reliever has been sidelined due to upcoming right wrist surgery, ending his season and removing him from the club's postseason roster.

What happened

The Guardians removed Holderman from their postseason roster after the right-hander was shut down for right wrist surgery, per MLB.com. Tim Stebbins' report makes clear that Holderman's season is over. No timetable for his return was included in the report.

The timing lands at an awkward moment. Cleveland clinched the AL Central title and secured a first-round bye just days before this news, meaning the Guardians will enter the postseason needing to account for the vacancy in their bullpen. The roster construction question that follows is now squarely in front of the front office.

Why it matters

Bullpen depth is the currency of October baseball, and any subtraction from a postseason roster demands an answer. The Guardians, who enter the ALDS with a first-round bye already in hand, will need to account for Holderman's absence when finalizing their pitching staff. That first-round bye, secured after Cleveland clinched the AL Central, does provide the organization a few additional days to sort through its options before the action begins.

The broader context here is a club that has been building toward this moment. Cleveland clinched their third consecutive playoff berth with a late-game comeback earlier in the week, and the AL Central title followed shortly after — the franchise's 7th division crown in 11 years, per prior Posterior Wire reporting. Losing a reliever to surgery on the eve of the postseason is the kind of logistical wrinkle that tests a roster's depth, and the Guardians will now find out what they have behind the names already penciled in.

The first-round bye gives Cleveland a margin that most clubs don't have at this stage. Under general postseason roster mechanics, clubs submit their roster before each series, which means the front office has some runway to evaluate its options before the ALDS begins. Whether that time is used to address the vacancy through a transaction or by promoting from within remains publicly unresolved.

Where the club stands

Cleveland enters October at 85-77 (.525), sitting first in the AL Central and holding the first-round bye that comes with it. The club is riding a one-game losing streak heading into the final days of the regular season, with two home games remaining against the Chicago White Sox at Progressive Field — Parker Messick is the probable starter Saturday, October 3, with Gavin Williams lined up for Monday, October 5.

Those final regular-season games carry a different weight now. With the division locked up and the bye secured, the priority shifts toward getting the roster right and keeping the healthy arms healthy. Per reporting from earlier in the week, Messick was expected to pitch only around three innings in the post-clinch hangover lineup, with Jose Ramirez, Rocchio, and Chase DeLauter among those slated for rest. The club is managing its people carefully, which is exactly the right posture when a surgery announcement is already on the board.

The numbers

The Guardians' offense has reasons for optimism heading into October. Chase DeLauter, in his rookie season, has been Cleveland's top hitter, posting a 131 wRC+ over 559 PA with 16 home runs, per prior Posterior Wire reporting. Steven Kwan, meanwhile, has posted a 178 wRC+ over his last 10 games after working through a prolonged mid-season slump, per earlier reporting — a stretch of production that would be welcome in any lineup come playoff time.

The club's 85-77 record reflects a team that earned its division title without running away from the field, which makes roster construction all the more consequential. Every arm on the postseason staff will matter, and the bullpen is now one name shorter than it was a week ago.

Is there a replacement named?

No. The MLB.com report, as written by Tim Stebbins, does not name a replacement for Holderman on the postseason roster. That decision remains publicly unannounced as of this report.

General postseason roster mechanics give clubs the ability to submit their roster before each series, which provides Cleveland some runway to evaluate its options before the ALDS begins. Who fills that spot — and from where — is the open question the front office is now working through.

What we don't know yet

The MLB.com report does not include a recovery timetable for Holderman beyond the fact that his season is over. No specifics about the scope of the procedure were provided, and the Posterior Wire does not speculate beyond what the material contains.

It is also not yet known who, if anyone, has been identified as Holderman's replacement on the postseason roster. The club has not publicly named a substitute, and the process of finalizing that decision is ongoing.

What to watch

The Guardians' postseason roster announcement is the next concrete development to track. Once Cleveland submits its ALDS roster, the gap left by Holderman's absence will either be filled by a name already in the organization or prompt a transaction that clarifies the club's thinking about its bullpen configuration.

In the meantime, the final two regular-season games against the White Sox — Saturday and Monday at Progressive Field — offer a low-stakes window to evaluate fringe roster candidates and keep the rotation on schedule. Messick and Williams are lined up for those starts, and how the bullpen is deployed around them may offer early signals about who is in the mix for October work.

The first-round bye gives Cleveland a margin that most clubs don't have at this stage. Whether the front office uses that time to address the Holderman vacancy through a transaction or simply promotes from within remains, for now, an open question.
