Seattle Mariners Preview

Seattle’s offense came through again in Game 5, producing well at the plate and keeping the Toronto bats quiet. Cal Raleigh continued his strong postseason and now has three home runs and a .429 on-base percentage, while Julio Rodríguez and Jorge Polanco have combined for 16 RBI in October. Josh Naylor’s .324 average adds another dangerous bat in the middle of the order. When the lineup puts runners on base, Seattle has shown it can break open innings against Toronto’s pitching.

On the mound, Logan Gilbert has led the rotation with a 2.45 ERA over 11 innings, and Bryce Miller has added 14.1 innings with a 2.51 ERA and 1.05 WHIP. The bullpen has been a real weapon, holding opponents to a .227 average and posting a combined 4.18 ERA through 97 innings. Andrés Muñoz has recorded two saves without allowing a run in 7.1 postseason innings, and Matt Brash has been nearly untouchable with one earned run over eight frames. Seattle has not announced its starting pitcher yet for Game 6.

Toronto Blue Jays Preview

Toronto faces elimination at home and turns to right-hander Trey Yesavage, who has struck out 15 batters in 9.1 postseason innings. When he keeps the ball down, Yesavage’s fastball-slider combination has been tough to hit, but early command of his pitches will decide how deep he can go. Toronto’s bullpen has been steady but will need to step up if the rookie starter runs into trouble against a patient Mariners lineup.
