LOS ANGELES — The New York Mets are down 3-2 to the Dodgers in the National League Championship Series, facing two potential elimination games on the road, but they hardly seem fazed.

Been there, done that.

Remember the Mets’ come-from-behind road win to clinch a playoff spot on the Monday before the postseason began? How about the down-to-the-last-out victory they pulled off in the wild-card round, when Pete Alonso took Milwaukee Brewers closer Devin Williams deep in the ninth? New York’s subsequent four-game division series upset over the Philadelphia Phillies seems anticlimactic in comparison.

And then came Game 5 of this series on Friday. The Mets pummeled Dodgers starter Jack Flaherty for eight runs in three innings, keeping their World Series hopes alive after losing Games 3 and 4 at home the previous two nights.

Now comes their toughest test to date. At Dodger Stadium, with its hostile crowd of more than 50,000 fans, the Mets need two wins against the team with the best record in baseball. In other words, the Mets have the Dodgers right where they want them.

“It wouldn’t be our story if it didn’t go this way,” veteran J.D. Martinez said with a smile after the Mets’ 12-6 win in Game 5. “This is how we do things.”

New York is looking to become the ninth postseason team to win Games 6 and 7 on the road — and recent history is on its side: Just last season, the sixth-seeded Arizona Diamondbacks went to the World Series after beating the Phillies twice at Citizens Bank Park.

It can be done. Will it happen is another question. Here are three reasons Mets players believe they can — and will — pull it off.

1. Their starting pitching has ‘carried us all year’

The Mets will have Sean Manaea starting on full rest in Game 6, followed by Luis Severino if they make it to Game 7. Both have come up big this postseason, particularly Manaea. Meanwhile, the Dodgers have a bullpen game scheduled for Sunday, followed by a diminished Walker Buehler, who hasn’t won a game in October yet, in a potential finale. New York could also use Jose Quintana out of the pen in either game.

“You could make a case that one of the big reasons we’re here is because of our starting pitching and their ability to go deep in games,” Mets manager Carlos Mendoza said this week.

But Manaea, Severino and Quintana haven’t looked sharp in their starts against the Dodgers this series. Combined, they pitched a total of only 13 innings across Games 2, 3 and 4. It was the first sign of fatigue from them this month.

“We also have to understand where we’re at in the season and where they’re at physically,” Mendoza said, “They’re in territory now where nobody expected it.”

Then again, Flaherty seemed to hit a wall in his latest outing, and Buehler needed 90 pitches to get through four innings in Game 3. Both teams might be looking at some gassed pitchers.

All things being equal — workloads included — the Mets think their starting pitchers put them in a good position.

“You have to be able to rise to the occasion and do whatever is asked of you,” outfielder Brandon Nimmo said. “Those guys have done that. Everyone has seen how they’ve pitched. There is so much confidence there.

“It’s carried us all year.”

2. Their lineup ‘broke through the dam’

It’s hard to make a case that any offense can go toe-to-toe with the Dodgers, who scored 30 runs in the first four games of this series, while adding six more in a Game 5 defeat. Even without a healthy Freddie Freeman, Los Angeles has done plenty of damage. But so, too, have the Mets — especially recently.

The Mets view Game 4 as a turning point. They scored just twice in a blowout loss, but had 13 runners reach base. Then in Game 5, they launched a 14-hit attack and scored 12 runs.

“We’re capable of putting together games like this, especially when one through nine, we’re clicking, we’re not chasing,” Mendoza said.

That might be more than manager-speak. For one, the bottom of the Mets’ order is starting to do some damage. Catcher Francisco Alvarez, who has hit in the nine-hole each game this series, credits a conversation he had with Starling Marte as a confidence boost.

“He came to me and he told me, ‘Hey, be happy,'” Alvarez recalled. “‘Play your game. Don’t try to do too much.’ But the real thing from Marte is he doesn’t talk too much, and I feel like he talked to me from the heart, and I appreciate him doing that.”

Alvarez is four for his past five in the series, while Marte has gotten hot as well. Marte, who hit sixth in Game 5, has nine hits over the past four games after going 0-for-4 in Game 1. On Friday, the Mets’ lineup looked as lengthy as the Dodgers’.

“Preventing their starters from going deep in games and getting to their bullpen, that’s huge, especially over this marathon-type of a series,” Alonso said. “And as an offense, that doesn’t happen if you don’t have quality at-bats. We’re having them now.”

Nimmo said: “We broke through the dam.”

3. They have ‘storybook-type stuff’

The “Meme Team,” as some like to call the Mets, doesn’t mind the corny nature of looking to Grimace or a lucky pumpkin for inspiration. It works for them. Some teams give off a buttoned-up attitude when they come to work, while others go with the flow. New York fits firmly in the latter category.

“We’re a frickin’ zoo in here,” Martinez said. “Would we be the Mets if we weren’t?”

No one epitomizes that fun — and belief — more than Alonso. The longtime Met might be in his final days with the team — he’s a free agent after this season — but he won’t let that distract him. In fact, it has kept him grounded and motivated, looking to keep this dream season going for as long as possible.

“This is what we all live for and play for,” Alonso said. “This is such a blast. And I think all of us — we’re just relishing in the moment and we’re looking to capitalize on opportunities.

“It’s storybook-type stuff.”

Alonso arrived in Los Angeles with the team’s Playoff Pumpkin intact, which the slugger seems more intent to talk about than his game-changing home runs this postseason. It’s managed with special care.

“White-glove service,” Alonso told ESPN with a big smile. “The pumpkin is taken care of almost as well as the Stanley Cup.”

Alonso keeps the pumpkin in his luggage, but carefully transports it from plane to hotel, from hotel to bus, from bus to clubhouse.

“On the road I’ve taken it back to the hotel because I don’t want any clubbies or anybody messing with it,” Alonso explained. “It’s kept safe every day.”

Pumpkins, mascots and “OMG” signs won’t be in the batter’s box when the first pitch is thrown in Game 6. But for the Mets, these things are part of who they are. Playing like this, with an unwavering spirit even with their season nearly always on the line, creates a winning atmosphere. Ahead of two win-or-go-home games, New York is banking on it.

“It’s something you learn by being here for a while,” Nimmo said. “You learn to not panic. If any team can do it, we can. We’ve played with our backs against the wall all year. We’ve risen to the occasion. Some might say we’re at our best in this time.”
