PHILADELPHIA -- The previous 330 times the New York Mets trailed by six runs in the ninth inning, they had lost.

"I'm sure everyone counted us out," Brandon Nimmo said. "These guys, they don't give up. With that mentality, anything is possible."

The Mets staged a most remarkable comeback Thursday night, erasing a six-run deficit in the ninth inning to beat the flabbergasted Philadelphia Phillies 8-7.

Nimmo delivered a tying, two-run single, then scored on Starling Marte's tiebreaking double to end a string of 857 consecutive losses by MLB clubs when trailing by six runs or more in the ninth, according to the Elias Sports Bureau.

"I'm an optimist, I just keep going until they blow the whistle," Nimmo said. "You just never give up. The stats can say all they want. They can say it can't be done. But that's why you play the game."

With the Mets trailing 7-1, Marte led off the inning with an infield single against James Norwood and scored on Francisco Lindor's two-run homer. Mark Canha added an RBI infield single that clanked off pitcher Corey Knebel (0-2), and J.D. Davis had a pinch-hit RBI double before Nimmo and Marte finished off the high point of the NL East-leading Mets' season so far.

"Just strung a lot of good at-bats together by good hitters," Mets manager Buck Showalter said.

It's the first time New York trailed by at least six runs in the ninth and won since Sept. 13, 1997, when Carl Everett hit a tying grand slam with two outs in the ninth and the Mets went on to beat the Montreal Expos in extra innings. It was just the third time in Mets history they have come back from at least six runs down in the ninth to win, according to Elias.

The Mets were as high as 60-1 to win at Caesars Sportsbook in the ninth inning.

Bryce Harper and Nick Castellanos homered for the Phillies, and Aaron Nola pitched seven sharp innings. The Phillies have lost five of six.

"That's about as hard as I've been through," Phillies manager Joe Girardi said. "This is as tough as it gets."

Marte also had a solo homer in the sixth.

The Mets avoided consecutive losses for the second time this season in amazing fashion, continuing the optimism in New York after a fast start.

"Nights like tonight make you realize what it can be," Showalter said.
