Blue Jays vs Mariners ALCS Game 4: Watch Live

The Toronto Blue Jays and Seattle Mariners are gearing up for a pivotal Game 4 in the 2025 American League Championship Series. Seattle leads 2-1 in the best-of-seven, and the stakes feel sky-high as both teams chase momentum.

After Toronto’s explosive win in Game 3, everyone’s talking about the pitching face-off: veteran Max Scherzer for the Jays and Seattle’s postseason ace Luis Castillo. This showdown at T-Mobile Park could really swing the direction of the ALCS.

Blue Jays Bounce Back in Dominant Fashion

Toronto walked into Game 3 knowing they had to win after losing the first two at home. The Blue Jays answered in a big way, putting on an offensive show and crushing the Mariners 13-4 for their first ALCS road victory since 1993.

The bats finally woke up, launching five home runs after managing just four runs total in the first two games. Vladimir Guerrero Jr. led the charge, going a perfect 4-for-4 with a homer, two doubles, and even drawing an intentional walk late in the game.

George Springer kept showing why he’s such a force in October. He collected three hits, including his 22nd career postseason home run, which just adds to his legend as a clutch player when it counts.

The Jays wasted no time, scoring twice in the first inning and quieting the packed Seattle crowd. By the third, they’d built a lead the Mariners couldn’t touch, totally flipping the script from their sluggish starts in Games 1 and 2.

Seattle’s Historic ALCS Homecoming Derailed

Game 3 wasn’t just another playoff game for Seattle—it marked the first ALCS home contest at T-Mobile Park since 2001. Fans filled the stadium, hoping to see their team grab a 3-0 series lead, but Guerrero, Springer, and the rest of Toronto had other ideas.

The Blue Jays took control early and never let go. Their relentless hitting drained the energy from the stands, leaving Mariners fans hoping for a turnaround in Game 4.

Mariners Still Holding Series Advantage

Even after the rough loss in Game 3, Seattle still leads 2-1 and keeps home-field advantage for Game 4 and maybe Game 5. The Mariners have battled through adversity all postseason, and now they’ll have to show they can bounce back again.

The Game 4 Pitching Duel

Thursday night’s focus shifts to the mound, where two very different stories play out. Toronto hands the ball to Max Scherzer, a postseason veteran who’s new to the Jays. Scherzer finished the regular season 5-5 with a 5.19 ERA, but he’s shown time and again that he can handle the pressure in October.

Castillo’s Command in October

Seattle counters with Luis Castillo, who’s been nearly untouchable this postseason. In two appearances, Castillo sports a 1-0 record and a razor-thin 0.83 ERA. His mix of speed and pinpoint control has baffled hitters, and he’ll try to push Seattle to the brink of the pennant.

What’s at Stake

Game 4 packs a ton of weight for both teams.

• If Toronto wins, the series ties at two games each. That would swing momentum their way, with another matchup left in Seattle.
• If Seattle pulls it off, they’ll jump out to a 3-1 lead and stand just a game away from the World Series.
• Managers have a tough call—should they trust their starters for a long stretch, or turn to the bullpen if things get dicey early?

The first pitch is set for 8:33 p.m. ET, airing on FS1 and streaming on Fubo. Fans all over North America will be glued to their screens, wondering if Toronto’s bats can stay hot or if Luis Castillo will slam the door for Seattle.

Honestly, postseason baseball is wild—momentum flips in a blink. Game 4 at T-Mobile Park might just become the turning point of the 2025 ALCS, with Scherzer’s experience up against Castillo’s electric stuff. It’s shaping up to be a classic October duel.
