In his first three at-bats Saturday, Gleyber Torres struck out three times against the Nationals’ Max Scherzer.

In his final two at-bats, against the Nationals bullpen, he got his bat on the ball for two of the weakest pieces of contact all game — and they sent the Yankees to victory.

After tying the game in the bottom of the ninth with an RBI single, Torres delivered a walk-off single in the 11th on a swinging bunt down the third-base line, lifting the Yankees to a wild 4-3 win over the Nationals at Yankee Stadium.

“It’s really easy to lose that mentality after three strikeouts,” Torres said. “But I just tried to be focused in that situation. I know baseball always [gives you] another opportunity to do something.”

Torres’ game-tying single to the opposite field in the ninth inning off Nationals closer Brad Hand, which spoiled Scherzer’s 14-strikeout gem, came off the bat at 70.8 mph. His game-winning infield single, which dribbled to the just the right spot to stump Washington, which was using five infielders, was 49.5 mph off the bat against Tanner Rainey.

“That’s just the crazy game we play,” said Aaron Judge, who had singled in the ninth and walked in the 11th to bring Torres to the plate for both key hits. “But happy to come away with the win. Right when I saw Gleyber coming up with bases loaded and no outs, I knew he was going to get it done.”

With a win that was delayed at the start for 2 hours and 25 minutes by rain, or at least the threat of it, the Yankees (17-16) snapped a two-game skid before heading into the finale of a nine-game homestand Sunday.

Most of Saturday’s game was a duel between former Cy Young winners Corey Kluber and Scherzer. Kluber was solid again, but Scherzer gave up just two hits — one a solo home run from Kyle Higashioka in the third inning — before exiting after 7 ¹/₃ innings and 109 pitches.

The Yankees then pounced on the Nationals’ bullpen, beginning in the ninth with Torres’ RBI single to tie it 2-2.

The Nationals answered by doing what no other team had done this season: They scored a run off Aroldis Chapman — though it was unearned, thanks to the automatic runner on second to begin the 10th inning. Victor Robles led off the frame with a single to put runners on the corners before Trea Turner hit a sacrifice fly to give the Nationals the 3-2 lead.

In the bottom of the 10th, with Clint Frazier starting on second, Mike Ford — who to that point was 3-for-36 on the season — began his at-bat trying to lay down a bunt. But after one foul attempt, he pulled back the bunt on three balls and then swung away for a single through the open left side to drive home Frazier and tie the game at 3-3.

“That is the motivation everybody got and everybody tried to follow that and win the game,” Torres said.

Justin Wilson, who had struggled in each of his last three appearances, settled the game down in the top of the 11th with a 1-2-3 inning. It set the stage for the Yankees to win it, with Giancarlo Stanton and Judge walking to load the bases for Torres’ heroics.

“Happy ending, for sure,” manager Aaron Boone said. “It hasn’t been easy for [Torres] necessarily at the plate, but he’s found a way and he’s gotten some big hits for us in some big spots, and a couple more today.”
