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

The Cleveland Guardians are opening the American League Championship Series without a named starter for Game 1, per MLB Trade Rumors' AJ Eustace, while the Tampa Bay Rays have already settled on Drew Rasmussen for Monday's opener at Tropicana Field. The series begins at 7pm CT.

What happened

Tampa Bay's decision was the easy one. Rasmussen is the Rays' ace, and the club tabbed him for Game 1 after dispatching the Yankees in a three-game Division Series sweep — a quick exit that left the entire Tampa rotation well-rested heading into the Championship round.

Cleveland's situation is considerably more complicated. The Guardians wrapped up a five-game ALDS against the White Sox only after rallying from a 2-0 series deficit, a comeback that required creative roster management and left their rotation in various states of availability. Per Eustace, the club had not announced a Game 1 starter as of the report.

The options, as laid out by MLB Trade Rumors, are Foster Griffin, Joey Cantillo, or Parker Messick on short rest. Griffin and Cantillo are described as fully rested, having been used for eight and five outs, respectively, in a bullpen game in ALDS Game 3. Messick threw only 65 pitches in a rocky Game 4 start, which means he could theoretically take the ball on short rest for ALCS Game 1 — though Eustace notes the likelier outcome is that Messick goes on full rest for Game 2. Monday's probable pitchers list Griffin opposite Rasmussen, though the Guardians have not made a formal declaration per the report.

Why it matters

The rotation uncertainty is not merely a Game 1 question. It cascades. Cleveland needs to account for at least Games 1 and 4 at a minimum, per the report, and how those decisions get made will shape the entire series structure for the Guardians.

Gavin Williams, who delivered 5 2/3 dominant innings with 12 strikeouts in ALDS Game 5 — two days after making an emergency relief appearance to close out Game 4 — is slotted for ALCS Game 3 on normal rest, per Eustace. That anchor gives Cleveland something to build around, but it also means the club is essentially constructing a rotation around a fixed point rather than working from the top down.

The Rays, by contrast, are working from the top down with considerable comfort. Rasmussen leads into Freddy Peralta for Game 2 and Nick Martinez for Game 3, per the report. Tampa's staff arrives at the ALCS rested and in order. Cleveland arrives having just survived.

The numbers

Rasmussen's regular season gives Cleveland something to prepare for. Per MLB Trade Rumors, he posted a 2.67 ERA across 30 starts, with a 21.2% strikeout-minus-walk rate and a 43.9% ground ball rate, both described as above average. FanGraphs credited him with 5.0 wins above replacement, which placed him just behind Cam Schlittler and Dylan Cease among the American League's best starters this year.

Messick, for his part, was right behind Rasmussen at 4.9 fWAR, per the report — a figure that underscores why Cleveland's rotation decisions carry real weight even when the sequencing is messy.

Peralta and Martinez are characterized by Eustace as solid rather than elite. Peralta struggled for two-thirds of the regular season before being traded to Tampa, then turned things around after the move, pitching to a 3.25 ERA across 55 1/3 innings in a Rays uniform and adding 4 2/3 innings of one-run ball in ALDS Game 2. Martinez was described as a bit off in his ALDS Game 3 outing, though his regular season was quietly strong: 180 innings, a 3.10 ERA, and a 3.6% walk rate that MLB Trade Rumors identifies as the best among qualified starters in the American League.

Cleveland's rotation counterparts — Griffin, Cantillo, and whoever else the club deploys in the early games — do not carry comparable regular-season résumés to that Tampa trio. That gap is part of what makes the Guardians' sequencing decisions so consequential.

Where the club stands

The Guardians finished the regular season 85-77 (.525), first in the AL Central, and enter the ALCS on a one-game losing streak. Their upcoming schedule is straightforward: Games 1 and 2 at Tropicana Field on Monday and Tuesday, then Game 3 at Progressive Field on Thursday.

Tampa Bay swept through the Division Series without apparent strain, which is the kind of luxury that lets a pitching staff arrive at a Championship Series in something resembling its natural state. Cleveland, having played five games against the White Sox and navigated a bullpen game, a rotation shuffle, and a Gavin Williams double-duty situation, is arriving in a different condition entirely.

What we don't know yet

The Guardians have not announced their Game 1 starter, and the report does not resolve that question — it only maps the options. Whether Cleveland goes with Griffin, Cantillo, or Messick on short rest for the opener remains undeclared as of Eustace's report.

There is also the matter of José Ramírez, who has been dealing with wrist pain during the postseason. Ramírez posted a .598 OPS in 53 regular-season games while returning from a fractured hamate bone, though he was described as heating up in ALDS Games 3 and 4. How he factors into Cleveland's lineup construction for the ALCS is not addressed in the report.

The broader rotation picture beyond Games 1 through 3 — who starts Game 4, how Cleveland handles a potential piggyback arrangement, whether any of the ALDS relievers are available on short rest — is also unresolved.

What to watch

The first thing to watch Monday is simply who Cleveland sends to the mound. Griffin is listed as the probable, but the club has not made a declaration per the report, and the gap between a probable and a formal announcement matters when the alternative is Messick on short rest or Cantillo in his first career postseason start.

Beyond Game 1, the series-level question is whether Cleveland's pitching depth — which was genuinely good enough to win the AL Central at 85-77 and survive a five-game ALDS — can hold up against a Tampa rotation that arrives rested, ordered, and led by one of the better starters in the American League this year. Rasmussen at a 2.67 ERA and 5.0 fWAR is a real problem for any offense. The Guardians will need to solve him before they can worry about Peralta and Martinez.

Williams on normal rest for Game 3 is Cleveland's clearest advantage in the early portion of the series. After 12 strikeouts in ALDS Game 5, he arrives at the ALCS with momentum and a full complement of rest. Whether the Guardians can keep the series close enough for that start to matter is the operational question the next 48 hours will begin to answer.
