The Toronto Blue Jays rode a stunning display from rookie pitcher Trey Yesavage and a Vladimir Guerrero Jr. grand slam to a 13-7 victory that pushed the New York Yankees to the brink of elimination in the playoffs on Sunday.

Daulton Varsho added two home runs as Toronto took a 2-0 lead in the best-of-five AL Division Series.

Guerrero smashed the first grand slam in Blue Jays playoff history to electrify the crowd at Toronto’s Rogers Centre.

Blue Jays fans were treated to five home runs, and a record-setting playoff debut from Yesavage.

Making just his fourth MLB start, the 22-year-old held the mighty Yankees lineup without a hit over 5⅓, striking out 11 with just one walk.

“When I was out there, I could feel the energy of the crowd,” Yesavage said. “I just knew something was gonna happen. I didn’t know it was gonna be all that.”

Toronto manager John Schneider said it was “tough to put into words” his thoughts on the performance by Yesavage, who rose through the minor leagues this season.

“The kid started in A-ball this year and just did that against that lineup,” Schneider said. “What we were looking for were command, poise, all that kind of stuff. That was there.”

Yesavage broke the previous Blue Jays record for strikeouts in a postseason game of eight and became the second-youngest pitcher with a double-digit strikeout game in the playoffs.

Guerrero’s fourth-inning blast to right field was followed by Varsho’s two-run homer to right center that pushed Toronto’s lead to 11-0.

The Jays hammered Yankees starting pitcher Max Fried through three innings, piling up eight hits on the way to a 5-0 lead.

That included a two-run homer in the second inning by Ernie Clement, who also singled in a run in the third. George Springer added a solo homer in the fifth that made it 12-0.

Aaron Judge got New York’s first hit of the game with a single off reliever Justin Bruihl, and Cody Bellinger followed with a home run that finally put the Yankees on the board in the top of the sixth.

Varsho answered with his second homer in the bottom of the frame.

The Yankees clawed out five runs in the seventh but that was the end of the fightback.

New York, which like the Blue Jays won 94 games this season but was edged out for the AL East division title on the tiebreaker, will now be fighting to stay alive when it hosts Game 3 on Tuesday.

“I know we’ll show up and ready to go expecting to win,” Yankees manager Aaron Boone said. “There’s been a lot of weird things that have happened in baseball this year. This would not be the weirdest, us rallying.”

The winner of the series will face either the Seattle Mariners or Detroit Tigers in the American League Championship Series.

The Mariners beat the Tigers 3-2 in the late game, knotting their series at one game apiece with their first home playoff win since 2001.

“We haven’t had a time like this in awhile, so being able to deliver a win like this, for the fans, was really special,” Julio Rodriguez said. “We know the job is not finished. Got to go out there (to Detroit) and grind and keep going.”

Mariners second baseman Jorge Polanco homered twice off Tigers ace Tarik Skubal — who is tipped to win his second straight AL Cy Young Award — to put Seattle up 2-0 through six innings.

Polanco pounced on a slider from Skubal in the fourth, driving it over the left-center field wall. With two outs in the sixth he lofted a pitch into the left field seats to double the score.

The Tigers tied it up in the eighth on Spencer Torkelson’s two-run double.
