Date & Time: Friday, October 13, 5:03 PM EST
Venue: Rogers Centre, Toronto, ON
Starting Pitchers: (RHP) vs. Trey Yesavage (RHP)
Moneyline Odds: Mariners +108 | Blue Jays -132
A high-stakes postseason showdown is set for Toronto as the Seattle Mariners visit the Blue Jays. The Mariners will send their established right-hander, Logan Gilbert, to the mound, while the Blue Jays will counter with rookie Trey Yesavage in a pressure-packed environment. Though oddsmakers have the Blue Jays as slight home favorites, significant injury questions surrounding Toronto could give the underdog Mariners a prime opportunity to steal a crucial road game.
Pitching Matchup
The story of this game begins and ends on the mound, where there is a stark contrast in experience. For Seattle, Logan Gilbert provides a steady, top-of-the-rotation presence. As the known commodity in this matchup, Gilbert will be tasked with silencing a potent Blue Jays lineup and capitalizing on the opposition’s pitching uncertainty.
For Toronto, the decision to start rookie Trey Yesavage in a postseason game speaks volumes about the team’s current pitching situation. The Blue Jays rotation has been dealt a massive blow, with a report from Sportsnet.ca confirming that ace José Berríos (elbow) will not be part of the Blue Jays’ ALDS roster. Berríos has yet to resume throwing, forcing Toronto to dig deep into its organizational depth and thrust the young Yesavage into the playoff spotlight. This puts immense pressure on the right-hander to perform on the biggest stage of his career.
X-Factors and Injuries
The Blue Jays’ injury woes extend beyond the pitching staff, creating major concerns for their offense. The status of superstar shortstop Bo Bichette remains the biggest question mark. After being placed on the 10-day IL in early September, reports from just before the postseason noted that while he wouldn’t return during the regular season, the team was receiving updates on his knee injury. Whether he is in the lineup for this series, and at what capacity, will be a critical factor in Toronto’s ability to produce runs.
The Mariners, meanwhile, appear to be the healthier club coming into this matchup. While they have managed their own share of injuries throughout the 2025 season to players like Bryce Miller and Luke Raley, they enter the postseason without the confirmed, series-altering absences that are plaguing the Blue Jays.
Prediction
While the Blue Jays have home-field advantage, their injury situation is too significant to overlook. The confirmed absence of José Berríos puts them in a precarious position, forcing a rookie to face a seasoned playoff contender. Add in the major uncertainty surrounding Bo Bichette’s availability and effectiveness, and the Blue Jays’ -132 line feels shaky.
The Mariners have a clear and decisive advantage in the starting pitching matchup with Logan Gilbert on the bump. He is more than capable of delivering a quality start to quiet the Toronto crowd. The Mariners’ offense should be able to take advantage of an inexperienced pitcher in a high-pressure situation. The +108 odds on Seattle represent excellent value for a team with the more reliable arm and a healthier lineup.
The Pick: Seattle Mariners (+108)
