The Guardians +105 moneyline is the strongest angle for the August 13 matchup at Comerica Park. Cleveland sends Parker Messick to the mound with a 9-6 record, a 2.57 ERA and 136 strikeouts, while Detroit counters with Keider Montero. DraftKings lists Detroit at -123, giving Cleveland a plus-money price despite the clearer starting-pitcher edge belonging to Messick.
The Tigers enter the finale with an 8-2 record over their last 10 games, but Riley Greene is now on the 10-day injured list after suffering a right hamstring strain. Greene was batting 0.273 with 16 home runs and 54 RBIs before the injury, removing one of Detroit's most productive bats from the lineup.
Guardians vs Tigers Game Preview
Detroit has won 8 of its last 10 games, including a 6-4 victory over Cleveland in the previous game of this series. Kevin McGonigle drove in 3 runs in that win, while Javier Báez scored twice, giving the Tigers another strong offensive performance at home.
GUARDIANS vs. TIGERS: Official Full Game Highlights (August 12) | 2026 MLB Season
Cleveland counters with Messick, who brings 136 strikeouts and 2.57 ERA into the series finale. Montero owns 86 strikeouts and a 3.38 ERA for Detroit, giving Cleveland the lower season ERA among the announced starters. The Tigers will also be without Greene, who was placed on the injured list with a right hamstring strain after leaving the previous game.
The situational setup favors a controlled afternoon game. First pitch is scheduled for 1:10 p.m. ET, with temperatures around 81°F, winds at only 3-5 mph and a rain chance of 0%-5%. Cleveland also gets a chance to respond immediately after Detroit's 6-4 win, while the Tigers enter the finale after winning 8 of their previous 10 games.

Moneyline Pick
Guardians ML is the pick at +105. Messick's 2.57 ERA gives Cleveland the better starting-pitcher number, and his 136 strikeouts show that the left-hander has the swing-and-miss ability to control
Detroit's lineup. Detroit's -123 price at DraftKings also gives the Tigers a heavier market expectation despite Montero carrying a 3.38 ERA.
Greene's absence adds another reason to take the underdog. The All-Star outfielder hit 0.273 with 54 RBIs and16 home runs before his hamstring injury, so Detroit loses a major source of production for this afternoon game.
Pick:
Guardians ML (+105 at DraftKings).
Run Line Pick
Guardians +1.5 is the run line side at -190. Cleveland gets a 1.5-run cushion behind Messick, whose 2.57 ERA is the best starting-pitcher number in this matchup, while Detroit is missing Greene's 0.273 batting average and 16 home runs.
Pick:
Guardians +1.5 (-190 at DraftKings).
Best Player Prop
- Steven Kwan Total Bases Over 1.5 (line provided, odds TBD at DraftKings).
Kwan enters the matchup on an 11-game hitting streak and is batting 0.425 over his last 10 games, with a double, a home run, seven walks and three RBIs. He faces Tigers right-hander Keider Montero, who has allowed Cleveland hitters a 0.209 average across 43 career at-bats, but Kwan has already shown strong recent contact form against Detroit.

Game Total Pick
Under 8.5 is the total pick. DraftKings lists the Under 8.5 at -120, and the starting pitching matchup supports a lower-scoring game with Messick carrying a 2.57 ERA and Montero a 3.38 ERA. Those numbers give both teams a reasonable path to avoiding an early scoring burst.
The weather also provides little help to the long-ball game. First pitch is expected to see temperatures around 81°F with winds of only 3 to 5 mph and a precipitation chance of 0%-5%, so there is no strong wind factor pushing the total upward. Detroit also loses Greene, who was batting 0.273 before suffering the hamstring injury.
Pick:
Under 8.5 (-120 at DraftKings).
Best Trades for Guardians vs Tigers
Prediction market pricing gives Cleveland a slight edge despite Detroit being the DraftKings favorite at -123. Polymarket has the Guardians at 53¢ in the game-winner market, while the Under 8.5 is priced at 54¢ and no first-inning run is at 55¢.
- Guardians game winner:
YES at 53¢ on Polymarket. Messick enters with a 2.57 ERA and 136 strikeouts, giving Cleveland the stronger announced starting-pitcher profile despite Detroit's recent 8-2 run over its last 10 games.
- Game total 8.5 runs:
NO at 54¢ on Polymarket. Messick's 2.57 ERA, Montero's 3.38 ERA and 3-5 mph winds point toward a controlled scoring environment.
- Run in the first inning:
NO at 55¢ on Polymarket. The first-inning market gives the no-run outcome a 55¢ share price, while the game features a 2.57 ERA starter in Messick and an 81°F afternoon with light winds.

- TV:
Detroit SportsNet, Guardians.TV Presented by Progressive.

Final Takeaways
The Guardians ML at +105 is the best price on the board because Messick has been the more reliable starter in this matchup, while Montero enters with a 3.38 ERA. Cleveland benefits from Greene's absence after the Tigers placed the All-Star outfielder on the 10-day injured list. The Under 8.5 at -120 is the secondary play, with two solid starters and light 3-5 mph winds creating a cleaner path to a lower-scoring game.
