The Yankees aren’t going to torpedo their way through the season.

They learned that Tuesday night in The Bronx, blowing a late lead to the Diamondbacks in a 7-5 loss, their first defeat of the year following a sweep of the Brewers to open 2025.

The Yankees still managed to hit three home runs, but that wasn’t enough to overcome a poor performance from the bullpen in a fateful five-run eighth inning.

Trying to hold onto a two-run lead, left-hander Tim Hill struggled before giving way to Mark Leiter Jr., who gave up a go-ahead grand slam with two outs to Eugenio Suárez.

Hill started the trouble by allowing a laser double to pinch hitter Randal Grichuk.

Grichuk scored on a Geraldo Perdomo single down the right field line to make it a one-run game.

Hill got Corbin Carroll on a comebacker before Leiter came in and walked the first two batters he faced to bring up Josh Naylor, a Yankee nemesis from his days with Cleveland.

With the bases loaded, Leiter struck out Naylor for the second out.

But Leiter and the Yankees paid for a 2-2 splitter that he didn’t bury, and Suárez turned on it for his fifth homer in five games.

The Yankees had taken the lead with the help of two more homers, and they finished the game with an MLB-record 18 through four games.

They scored two runs on a Naylor error at first base to give them the lead in the fourth. But they weren’t able to add to the advantage and wasted a solid season debut from Will Warren, who gave up just two runs in five innings.

The Yankee offense made new Arizona ace Corbin Burnes work, as he threw 98 pitches while getting just one out into the fifth inning.

They weren’t able to solve Arizona’s pen, though, as four relievers shut the Yankees down for 4 ²/₃ innings until Ben Rice’s solo shot with two outs in the bottom of the ninth.

There were no base runners in the game until Perdomo, Arizona’s No. 9 hitter, walked on four pitches with two outs in the top of the third.

Carroll followed with a two-run shot into the seats in right.

The Yankees got their first base runner — and run — when Jasson Domínguez led off the bottom of the inning with a shot to right-center.

Rice then slammed a double to the gap and Oswaldo Cabrera walked before Burnes recovered to retire the top of the lineup again.

Warren walked the first two batters in the fourth, but got Suárez to hit into a double play and Gabriel Moreno to ground out to end the threat.

Anthony Volpe tied the game with one out in the bottom of the fourth with his third homer of the season, a 418-foot shot into the visiting bullpen in left-center.

The Yankees took the lead later in the inning, not because of a torpedo, but with an error.

With runners on second and third and two out, Cabrera grounded to first, where Naylor flipped high to Burnes.

The ball sailed over Burnes, and Austin Wells and Domínguez both scored to make it 4-2.

Warren left after five innings, but not before pitching out of some trouble in his final inning.

With Jake McCarthy on second, following a leadoff walk, and two outs, the Yankees opted to keep Warren in the game to face Carroll one more time.

After a visit from pitching coach Matt Blake, Warren responded by striking out Carroll to preserve the two-run lead.

Fernando Cruz entered and tossed two shutout innings, with four strikeouts, but the rest of the pen couldn’t close the deal.
