Out with the old, in with the new.

That’s the Mets mantra going forward as Curtis Granderson and Rene Rivera were the latest veteran casualties to be shipped out of town in less than 24 hours.

With a team now almost exclusively comprised of young bloods, the Mets took to the field and snapped their five game skid in support of Rafael Montero on Saturday.

“I think my sinker was working really well for me tonight,” Montero said. “I was able to get a lot of double plays out of that.”

Montero (2-8) issued a couple walks and sprinkled a few hits over the first five innings, but thanks to some key double plays, the righty was able to keep the Fish at bay.

Marcell Ozuna broke the silence for the Marlins in the sixth after singling home Dee Gordon, but Montero buckled down to strike out Miami’s backstop J.T. Realmuto with two on to end the threat.

The Mets evened the score in the bottom of the frame on a sacrifice fly from Asdrubal Cabrera after Matt Reynolds walked and Brandon Nimmo scored, which chased Worley from the game.

Drew Steckenrider then took the mound for the Marlins and issued a single to Yoenis Cespedes, but the real damage came when Wilmer Flores clubbed a two-run bomb after a costly fielding gaff by Miguel Rojas the at-bat prior to bust the game open 5-1.

Rojas committed another error on the next play, this time off the bat of Dominic Smith, and the Mets made him pay again as newly recalled Kevin Plawecki launched his first bomb of the season to give the Mets a seven spot in the inning.

Smith put the icing on the cake in the eighth with his second big league homer.

“First couple [at-bats], I’m not going lie, it almost felt like my first in the big leagues again,” said Plawecki, whose last home run came on May 9, 2016. “But being able to go out there and contribute in that inning was definitely big. It felt good.”

His blast would prove to be more than enough, as Hansel Robles and Chasen Bradford combined to fire three scoreless innings out of the ‘pen in relief of Montero to finish off the victory.

Each Met in the starting lineup chipped in a base knock on Saturday, excluding Montero. A positive sign from the youngsters such as Nimmo and the aforementioned Plawecki who are sure to get closer looks in the final stretch of the season.

“I can’t look at it as a huge pressure situation or anything like that. I’m not going to do it,” Plawecki said of the importance of the final six weeks for him. “It is what it is. What’s done is done. But I’m happy with the work I’ve been able to put in and I’m really looking forward to this last six weeks of the season and hopefully on to next year.”

Manager Terry Collins said after the game that he expects Plawecki to start three of every six games for the remainder of the season.

With the uncertainty surrounding Travis d’Arnaud‘s future, New York wants to see what their catching situation is like to give them clarity prior to the offseason.

“I don’t think we’re just saying, hey, we’re handing the reigns over the Kevin Plawecki,” Mets manager Terry Collins said. “I think we’ve got to do diligence and make sure both these guys are getting playing time, ample playing time to show us what they can do.”

As for Montero, the righty has made positive strides in his previous two starts and could finally be turning a corner, looking to work his way into the Mets future plans.

“The Yankees start was the best I’ve seen him throw with pure stuff – velocity and secondary pitches,” Collins said. “I just thought (on Saturday), he used his fastball so much more effectively. He pitched in on some guys, kept the ball down in the zone. He used his slider occasionally, but he really made it hurt with the fastball.”

For New York, the rookies and younger guys will be on full display the rest of the season, and as they hope, maybe a few of them can make a difference for the future like they did on Saturday night.
