For the second start in a row, Gerrit Cole was burned by a long-ball barrage.

The Yankees ace surrendered three more home runs in Saturday’s 12-2 loss to the Mets in the Bronx and has now served up seven homers over his last two outings.

Those are the most home runs Cole has allowed over any two-start stretch in his 13-year MLB career.

“It’s something we’ve got to figure out, for sure,” Cole, 36, said. “It’s just one of those times in the season where you’ve got to start making adjustments. Sometimes, adjustments are hard, but that’s the demand of the game, right?

Francisco Lindor, Luis Torrens and Carson Benge all took Cole deep during a lopsided afternoon in which the Mets totaled six homers to even the Subway Series.

That’s after Cole gave up four solo homers in his previous start last Sunday in San Diego, including back-to-back-to-back blasts to begin that day’s 4-3 loss.

Physically, Cole says he feels fine — no small feat now that he’s 20 starts into his return from the Tommy John surgery that sidelined him for all of last season and the start of this one.

But Cole acknowledged Saturday that the lack of swing-and-miss he’s generated is “something that we need to tackle.”

Cole entered Saturday with a 22.3% whiff percentage — his lowest since 2016 — and then elicited only three swings-and-misses out of his 77 pitches against the Mets.

The right-handed Cole’s 24.9% strikeout rate going into Saturday was his lowest since 2015.

“It’s part of the product of being in the strike zone as much as he is,” said manager Aaron Boone, who felt Cole wasn’t able to hit his spots against the Mets (69-79).

“When he’s executing at that highest level, there will be that swing-and-miss in there, because I feel like the stuff is there.”

All told, the Mets tagged Cole for five runs on nine hits over 4.1 innings.

Saturday marked the second straight start in which Cole gave up a home run to the game’s first batter, as Lindor led off the top of the first by pulling an 85.8-mph changeup into the right-field porch.

Torrens followed with a two-run homer off of a 97.7-mph fastball with two outs in third.

And in the fourth, Benge got just enough of a hanging, 89.5-mph slider and drove it 368 feet into the first row of the stands in right-center.

The Mets recorded 14 batted balls with an exit velocity of at least 95 mph — or “hard hits,” as MLB’s Statcast defines it — against the 2023 American League Cy Young Award winner.

“Usually, guys like him don’t make too many mistakes. When they do, you’ve got to try to make them pay,” said Lindor, who also struck a grand slam against reliever Bradley Hanner in the eighth inning and finished 3-for-5.

Three of the homers Cole allowed in San Diego were against his fastball, which, entering Saturday, was averaging 96.9 mph — a few ticks higher than his pre-surgery form.

After giving up only 13 home runs in his first 18 starts, Cole has now allowed seven homers over his last 11.1 innings.

It’s a sudden rough stretch in what’s been a successful comeback season for Cole, who returned on May 22, some 14 months after the major elbow surgery.

With Saturday’s loss, Cole fell to 8-9 with a 3.67 ERA and 117 strikeouts in 115.1 innings.

“I’m in a good spot in terms of health and stamina,” Cole said. “I just need better efficacy for preventing runs.”

Asked Saturday if he felt his recent slide was related to his post-surgery progression, Cole said it’s “hard for me to pin it on one thing” but that sometimes good offenses “teach you lessons” over the course of a long season.

With 14 games left in the regular season, Cole likely has two more starts to straighten out his home-run issues before the playoffs.

“Things can turn around quickly,” Cole said. “You look at it one game at a time. I’m not looking at the next two weeks. You never really know how close you are. Sometimes it’s really, really small things.”

Cole was out-pitched by Mets rookie Zac Thornton, who held the Yankees (85-63) to two runs over seven innings.

Saturday’s game continued to unravel after Cole departed, as Juan Soto hit a solo home run against left-hander Tim Hill in the seventh. That was Soto’s first home run in the Bronx since he left the Yankees for a 15-year, $765 million contract with crosstown Mets before the 2025 season.

Lindor’s grand slam punctuated a five-run eighth and secured the shortstop’s second multi-homer game of the season. Jared Young capped the power surge with a ninth-inning solo shot against Hanner.

“We didn’t miss the ball,” said Soto, who brushed off his latest round of boos in the Bronx to go 2-for-5. “We made success, we swung the [bat] the right way, we picked our moments and we capitalized.”
