They are together. They are reborn. They are emboldened.

The Mets have their sights set on something much bigger than the NL wild card with the Nationals coming to town Friday for this Showdown Series, aces wild.

“We’ve got a chance to do something really great,’’ slugger Pete Alonso said after the Mets whipped the Marlins 7-2 Wednesday at Citi Field behind home runs from Alonso (his 37th), two by Michael Conforto and one by Jeff McNeil, along with another strong effort at home from Steven Matz.

The Mets have won 13 of 14, equaling their best 14-game run in 29 years, to get back to playing meaningful games.

Yes, meaningful games with the Mets. They are just a half-game back of the Phillies and Brewers for the second wild card and 8¹/₂ games behind the division-leading Braves. The Nationals hold the first wild card with a 61-53 mark. The Mets are 59-56.

After three games against Washington, the Mets head to Atlanta for three against the NL East-leading Braves.

These next six games hold the key to the Mets season.

They don’t expect to stop now even though the Nationals are firing Stephen Strasburg, Patrick Corbin and Anibal Sanchez against Marcus Stroman, Noah Syndergaard and Jacob deGrom this weekend.

“We’ve got some really tough games ahead of us,’’ Alonso said, “but let’s say we keep this up and win all six or win five out of six, that’s going to put us not just in wild-card talks but a chance to win the division. If we keep rolling the way we are I know we are getting down to the nitty gritty, but we have an awesome chance to do something really special and make a hell of a run towards the end.’’

The Mets are no longer facing the dregs of the NL like they did in this four-game sweep of the Marlins or in taking five of six from the Pirates and three straight from the White Sox.

Now comes the true test, and the Mets to a man say they are ready.

“You got to slay the giant so to speak,’’ Alonso said. “You have to go through these tough teams in order to get to the playoffs, and when you get to the playoffs it’s just going to be that much harder. If we keep playing the way we are, we’ve hit well, our defense has been awesome and our pitching has been light’s out, so I think that’s going to be a really tough combo.’’

Since the All-Star break, the Mets are 19-6. Their starters own a 2.62 ERA since the break, the best mark in baseball.

All the tough times the Mets have been through has strengthened them. But now they have to prove it against the big boys in the division.

“What we’ve done is not easy, but it’s in the past,’’ Mickey Callaway said of the Mets’ mindset. “Our focus is on the next game. The things that we’ve been through are going to allow us to be a better team than we otherwise would have been down the stretch. We’re trying to accomplish something as a team together that can be very special. The rough patches have only brought us closer together.

“If we were a team that had just breezed through until now and been in a similar spot, we wouldn’t be as close of a unit. There is a silver lining to our struggles, but we’ve got to perform. You can be the closest knit group you want, you still have to perform and that is what we’ve been doing lately.’’

It’s good that Callaway is not living in dream land, but reality.

The Mets have to show the Nationals they belong in the race.

“At the end of the day or at the end of the year, we are going to be in a really good spot,’’ Alonso said, almost as a promise.

Yes, the Mets have worked hard to put themselves in this meaningful spot. Take care of the Nationals like they took care of the lowly Marlins and the Mets will be in great shape with the wild card and knocking on the NL East front door.

They need to be weekend warriors, too.
