Mets should keep this youth movement going

Changes are coming. Changes are here.

The Mets are getting desperate enough to take a different look at their team. It’s about time.

There will be changes in personnel and approaches, too. Rookie Eric Campbell made a terrific diving catch in the eighth inning of his first major league game in left field on a sinking line drive off the bat of Hanley Ramirez. Campbell turned it into a double play when wild-horse base runner Yasiel Puig took off from second.

That was a key play in the Mets’ madcap 5-3 win over the Dodgers at Citi Field on Thursday night.

After the victory, which snapped a three-game losing streak, Terry Collins said he will use Campbell in the middle infield as well as at the corners, too, a Soup-er utility Campbell.

Collins said more young players will be coming up to help the Mets. Jenrry Mejia got the save and worked consecutive games for the first time since 2010.

“This is what we thought for awhile, we have young guys who are making a contribution and we have more coming,’’ Collins promised. “We have some position players not far away. Young guys are starting to pop up here and they are making a difference.’’

That is the right approach.

Campbell, 27, had been a career minor leaguer who was so unsure of his baseball future, he worked offseason jobs the last few years back home in Norwich, Conn.

“I’ve done a lot of different things,’’ he told The Post. “I’ve been a substitute teacher for high school, I worked with my brother flipping houses a little bit. This year I had a computer job with my friend’s father from home. Just try to make a buck here and there.

“I wondered last year if I would ever get a chance to play in the big leagues because there are a lot of good players that play in Triple-A that never get that chance.’’

Just look at Yangervis Solarte with the Yankees.

“Exactly,’’ Campbell said. “And I thought he was one of the better players every time I played against him. It really does take a little bit of luck to get in there. I’m trying to make sure that once I got that chance, I will never go back.’’

Campbell drove in the Mets’ first run against Zack Greinke with a sacrifice fly, but it was the catch that made his night.

“You put a guy in for his offense and his defense saves the game,’’ Collins said. “I’m going to play this guy in the middle of the infield, too. He’s athletic enough to play [second and short].’’

There also are changes in approach. David Wright told The Post he is being more aggressive, especially early in the count. Less taking, more swinging.

Wright picked up two hits Thursday and has an NL-high 30 hits this month. The Mets got a huge two-out, 0-2 single from Juan Lagares to drive in the go-ahead run in the seventh and a double and triple from Curtis Granderson, who broke out his Kevin Long home run drill on Tuesday when he singled, doubled and homered.

Collins needs all the wins he can get because if the Mets don’t turn it around, there will be plenty of heat on the manager.

“When we start swinging the bats and we get hot, we’ll be back and we’ll get back on the horse,’’ Collins said before the game. “We’re not playing good and we’re five games out. That can be made up real fast, especially in our division.’’

Then the Mets went out and got some big hits and big plays.

This was a night as an organization the Mets were more adaptable. Lagares hit leadoff for the 12th time and is batting .347 this season hitting first. Chris Young and Eric Young Jr. were not in the starting lineup. Collins had more depth on his bench.

“The young guys bring energy, they’re still hungry,’’ Collins said.

You saw that hunger on Campbell’s diving catch.

That hungry approach and catch made the difference. A nice change.
