TORONTO — The Yankees played spoiler for two nights, but could not hold down the Blue Jays for a third.

After getting shut out through the first 20 innings of the series, the Blue Jays finally broke out to avoid a sweep and beat the Yankees 6-0 on Thursday night at Rogers Centre.

While the Blue Jays (88-71) inched closer to locking up an AL wild card, the Yankees (81-78) flew to Kansas City needing one win in their final three games to secure their 31st straight winning season.

Luke Weaver gave up a pair of solo home runs to Daulton Varsho and Matt Chapman during his four-inning start before the Blue Jays broke the game open against Greg Weissert (one run) and Zach McAllister (three runs).

Former Met Chris Bassitt, meanwhile, struck out 12 across 7 ²/₃ shutout innings.

He whiffed Aaron Judge on his 106th and final pitch of the night to hit 200 innings for the first time in his career.

Yoendrys Gomez, the Yankees’ 23-year-old right-hander who spent this season as a starter at Double-A, made his MLB debut by tossing two scoreless innings of relief to close the game.

Gomez struck out four while giving up a bloop single and hitting a batter.

“Did a pretty good of executing, especially with his fastball at the top of the strike zone,” manager Aaron Boone said. “For a young player, he’s been through a lot, had his injury ups and downs. But he’s definitely a guy with a lot of talent and somebody we’re excited about.”

Gomez, rated the Yankees’ No. 26 prospect per MLB.com, was called up last Friday before having to wait nearly a week to get his first action.

“That moment in the bullpen when the phone rings, you get nervous,” Gomez said through an interpreter. “It’s the first time they call for you. You feel your heart beating at 1,000 miles per hour. But then you get on the mound and everything goes away and you just make pitches.”
