Toronto Blue Jays vs Seattle Mariners Betting Preview
The Seattle Mariners look to take a commanding 2-0 lead over the Toronto Blue Jays in the American League Championship Series when they meet on Monday, October 13, 2025, at Rogers Centre. First pitch is set for 5:03 PM ET on FS1.
Seattle stole home-field advantage with a 3-1 victory in Game 1, their third straight postseason win. Despite coming off a 15-inning ALDS clincher over Detroit, the Mariners showed no fatigue behind Bryce Miller, who held Toronto to one run across six innings.
Now they turn to Logan Gilbert, who worked two innings in relief Friday and owns a 1.13 ERA this postseason. Gilbert has struggled historically against Toronto (0-2, 5.24 ERA in six starts) but feels ready after what he called a “high-intensity bullpen” outing in Detroit.
Toronto counters with rookie Trey Yesavage, who dazzled in the ALDS against the Yankees — 11 strikeouts over 5 ⅓ scoreless innings. Manager John Schneider said starting Yesavage was an easy call, praising his poise and “unique stuff” against lineups that haven’t seen him.
The series shifts to Seattle after Game 2 for up to three games if needed.
Blue Jays vs Mariners Line Movement and Odds
Oddsmakers opened Toronto as a −129 favorite, with Seattle at +110 on the moneyline. The run line shows Blue Jays −1.5 (+163) and Mariners +1.5 (−196), while the total sits at 7.5 runs.
The line reflects respect for Toronto’s home-field edge and deeper rotation, even after dropping Game 1. Early money came in on Seattle after their strong pitching performance, tightening the number slightly before settling back near its opener.
Totals betting leans toward the over 7.5, as bettors expect some regression from two staffs that combined for a low-scoring opener. For live movement and updated prices, visit the MLB Odds page.

Matchup Breakdown
Seattle Mariners Outlook:
Seattle’s Game 1 win showed balance across the board — strong pitching, patient at-bats, and timely power. Bryce Miller gave six efficient innings, while Cal Raleigh homered and Jorge Polanco drove in a key run. The Mariners ranked third in home runs during the regular season (241 total) and continue to rely on long-ball power from Julio Rodríguez and Eugenio Suárez, who combined for 81 homers.
Logan Gilbert takes the mound in Game 2 with a postseason ERA of 1.13. He’s 0-2 with a 5.24 ERA lifetime vs Toronto, but manager Dan Wilson said the short relief outing in the ALDS was “a good side day” that kept Gilbert sharp. Seattle’s bullpen has been reliable with a 3.87 team ERA and 67 quality starts this season.
Toronto Blue Jays Outlook:
The Blue Jays’ offense struggled to convert in Game 1 despite a solo homer from George Springer. They’ll look for better results behind rookie Trey Yesavage, who dominated the Yankees with 11 Ks in 5 ⅓ scoreless innings.
Toronto finished the regular season ranked first in team batting average (.265) and third in doubles (294), led by Vladimir Guerrero Jr., Bo Bichette, and Springer. They’ll need that contact strength to offset Seattle’s power and bullpen edge.
Key Factor:
Toronto must get to Gilbert early. If Yesavage can navigate Seattle’s order twice, Toronto’s rested bullpen can pull them even. If not, Seattle could head home up 2-0.
Injuries and Conditions
Seattle Mariners Injury Report
Seattle enters Game 2 mostly healthy. Reliever Andrés Muñoz threw a side session Saturday and remains available out of the bullpen. Tom Murphy (shoulder) is off the ALCS roster, but Cal Raleigh continues to catch every inning. See the Seattle Mariners injury report for late updates before first pitch.
Toronto Blue Jays Injury Report
Toronto activated veterans Max Scherzer and Chris Bassitt for the ALCS, adding depth behind the rookie. Both are available in long relief if needed. No new lineup injuries were reported Sunday. Check the Toronto Blue Jays injury report for the latest player statuses.
Game Conditions:
The roof at Rogers Centre is expected to be closed for Game 2, keeping conditions controlled. No weather factors should affect either starter.
Best Bets and Prediction
The Mariners enter Game 2 with confidence and the comfort of already flipping home-field advantage. Logan Gilbert has been one of Seattle’s most dependable arms, posting a 3.44 ERA with a 1.03 WHIP. His command and Seattle’s power give them a chance to head home up 2-0.
Toronto, however, still owns the more consistent offense. The Blue Jays led MLB in batting average (.265) and on-base percentage (.337), and their core hitters — Vladimir Guerrero Jr. and Bo Bichette — are heating up. If rookie Trey Yesavage mirrors his ALDS form, Toronto can even the series.
- Projected Score: Blue Jays 5, Mariners 4
- Best Bet: Over 7.5 runs (−113)
- Secondary Lean: Blue Jays Moneyline (−129)
