Toronto Blue Jays Preview

Toronto has scored only four runs in the first two games of the ALCS and has struggled to keep rallies going. The Blue Jays had seven hits in Game 2 but went just 2-for-10 with runners in scoring position. Vladimir Guerrero Jr. continues to lead the Blue Jays at the plate, hitting .429 with three home runs and nine RBI this postseason. Daulton Varsho (.368, two home runs) and Ernie Clement (.529) have helped, but the rest of the order has been quiet and has struggled without Bo Bichette.

Shane Bieber starts Game 3 after allowing five hits and one run in 2.2 innings in his last outing. The right-hander needs a solid performance to keep Toronto close and ease the load on the bullpen. The pitching staff has allowed 13 runs through the first two games. Toronto’s lineup must put more runners on base, followed by timely hitting to avoid falling behind early again, as the series is already getting away from them.

Seattle Mariners Preview

Seattle returns home in control after two wins in Toronto. The Mariners have outscored the Blue Jays 13–4 in the series, led by Cal Raleigh, who is batting .400 with two home runs and five RBI. Jorge Polanco has matched that production, and Julio Rodríguez has added timely hits throughout the postseason. Seattle’s lineup has been steady and will look to continue hitting Toronto's pitching.

Toronto Blue Jays vs Seattle Mariners Prediction

Seattle has controlled the series through stronger pitching and better hitting. Bieber’s short outing last time raises concerns about Toronto’s bullpen, which has been overworked through two games of the series, while Kirby’s consistent command puts less pressure on the Mariners' pen. Unless Toronto’s middle of the order produces, Seattle’s pitching and timely hitting will put the Mariners up 3-0. Final Score Prediction: Seattle Mariners win 5-3.
