Guardians haven't named a Game 1 ALCS starter as series opens Monday at Tampa Bay

What happened

The Cleveland Guardians have not announced a Game 1 starter for the American League Championship Series, which opens Monday at Tropicana Field against the Tampa Bay Rays, per MLB Trade Rumors. Tampa Bay, meanwhile, has tabbed Drew Rasmussen for the assignment. The seven-game series begins at 7 p.m. CT, with the Rays serving as hosts for the first two games.

Why it matters

The Guardians' rotation situation is genuinely unsettled heading into the ALCS, and it is not entirely by design. Cleveland just finished a five-game Division Series against the White Sox — a series that required a comeback from a 2-0 deficit, forced a Game 5, and leaned heavily on its pitching staff in ways that now complicate the sequencing for the Championship round.

Gavin Williams, who started Game 5 of the ALDS two days after pitching in relief in Game 4, delivered 5 2/3 dominant innings with 12 strikeouts in that clincher, per MLB Trade Rumors. That performance was essential to Cleveland's survival, but it also means Williams will not be available until Game 3 of the ALCS on normal rest. Parker Messick, who started Games 1 and 4 of the ALDS, threw only 65 pitches in a rocky Game 4 outing. Per MLB Trade Rumors, Messick could theoretically start Game 1 on short rest, though the likelier outcome is that he takes the ball for Game 2 on full rest.

That leaves Games 1 and 4 — at a minimum — as open questions. Foster Griffin and Joey Cantillo each worked in the ALDS Game 3 bullpen game, getting eight and five outs respectively, and both are fully rested. Tanner Bibee was used in Game 4 and recorded only one out. Per MLB Trade Rumors, Griffin, Cantillo, and Messick on short rest are each under consideration for Game 1, though Cleveland has not indicated which direction it will go.

The Rays, by contrast, arrive well-rested. Tampa Bay swept the Yankees in three games and enters the ALCS with its rotation aligned and its ace ready to go.

The numbers

Rasmussen broke out as Tampa Bay's ace during the regular season, posting a 2.67 ERA across 30 starts with a 21.2% strikeout-to-walk rate and a 43.9% ground ball rate, both above average, per MLB Trade Rumors. FanGraphs credited him with 5.0 wins above replacement — a figure that placed him just behind Cam Schlittler and Dylan Cease among the best starters in the American League. Messick was right behind him at 4.9 fWAR.

The Rays' rotation does not stop at Rasmussen. Freddy Peralta and Nick Martinez are lined up for Games 2 and 3. Peralta struggled for two-thirds of the regular season before turning things around following his trade to Tampa, posting a 3.25 ERA in 55 1/3 innings with the club. He then tacked on 4 2/3 innings of one-run work in ALDS Game 2, per MLB Trade Rumors. Martinez was uneven in his ALDS Game 3 outing, per MLB Trade Rumors, yet quietly assembled a strong regular season: 180 innings, a 3.10 ERA, and a 3.6% walk rate that led all qualified starters in the American League.

Where the club stands

The Guardians finished the regular season 85-77 (.525), first in the AL Central. They enter the ALCS on a one-game losing streak — a streak that, given the context, is a single-game bookkeeping artifact from a team that just won a five-game playoff series. Their upcoming schedule is straightforward: Games 1 and 2 on Monday, October 12 and Tuesday, October 13 at Tropicana Field, with Game 3 shifting to Progressive Field on Thursday, October 15.

The Rays hold home-field advantage as the higher seed, which means Cleveland will need to navigate at least the first two games in Tampa Bay before returning to its own park.

What we don't know yet

The most immediate open question is who starts Game 1 for Cleveland. The club has not announced a starter, and per MLB Trade Rumors, the candidates represent meaningfully different options in terms of workload, experience, and what they would leave available for later in the series.

There is also the matter of José Ramírez, who has been dealing with wrist pain during the ALDS. Ramírez posted a .598 OPS in 53 regular-season games while returning from a fractured hamate bone, though he was heating up in ALDS Games 3 and 4. He has downplayed the wrist pain as an excuse for his struggles, but how he holds up through a seven-game series against a well-rested pitching staff is a thread worth following.

The Guardians' Game 4 starter is also unresolved. Depending on how Games 1 through 3 unfold — and how many pitches various arms accumulate — Cleveland's options for Game 4 could look quite different by the time the series gets there.

What to watch

### Who starts Game 1 for Cleveland?

Cleveland has not said. The answer, whenever it comes, will tell you a great deal about how the Guardians are thinking about the series as a whole. A Griffin or Cantillo start in Game 1 preserves Messick for Game 2 on full rest and keeps Williams on track for Game 3 — a sequencing that would give Cleveland two of its better arms in the middle of the series. Messick on short rest in Game 1 is the riskier path, given that he threw only 65 pitches in a rocky outing just days ago.

On the Tampa Bay side, the question is whether Rasmussen's regular-season dominance — a 2.67 ERA, 5.0 fWAR, and a ground-ball rate that should play well in any park — translates to a postseason Game 1 against a Cleveland lineup that just spent five games grinding through the White Sox staff. The Rays' rotation depth is real, and the rest advantage is real. Whether Cleveland's bullpen-and-patchwork approach to Game 1 can keep the series close early is the central operational tension of the opening games.

The series begins Monday. Cleveland's announcement, presumably, comes before then.
