PORT ST. LUCIE — The planets are aligning, so much so that Juan Lagares could begin the season with another team.

According to industry sources, the Mets have received recent phone calls about the former Gold Glove winner and haven’t ruled out the idea of trading him. The trade buzz comes as Brandon Nimmo has emerged in camp as the potential fourth outfielder once Michael Conforto returns. Conforto, who is rehabbing from September shoulder surgery, told The Post on Tuesday that he expects to play in a Grapefruit League game next week, which could possibly put him on track to return before May 1, as the team has outlined.

Lagares began camp as the favorite to play on a regular basis in center field until Conforto returns, but Lagares’ struggles at the plate, after a winter spent retooling his swing, haven’t helped his case. Entering Tuesday’s play Lagares was 4-for-20 (.200) in seven exhibition games.

A source indicated at least one American League club has maintained interest in Lagares, who is making $6.5 million this season. He is scheduled to receive $9 million in 2019, the final year of his contract.

The caveat in trading Lagares, who turns 29 this week, is such a move could leave the Mets thin on outfield depth. As it stands, Matt den Dekker and perhaps Phillip Evans are behind Nimmo on the depth chart.

But the Mets could also look to acquire a serviceable backup outfielder in any trade involving Lagares.

Team officials listened to trade proposals involving Lagares in the offseason, but were extremely hesitant to deal him because of the uncertainty surrounding the outfield given Conforto’s rehab and the fact Jay Bruce wasn’t signed until Jan. 16.

Nimmo smashed his third home run of the spring on Tuesday, with a leadoff blast against the Astros’ Gerrit Cole and is 12-for-35 (.343) in the Grapefruit League.

“It’s spring training, so it’s hard to read into what spring training means for the front office, to the coaches and to this team,” Nimmo said. “But I am just trying to do the very best that I can every day and feel like I am facing good competitors out there and good pitching.

“It’s not just Joe Schmoe that I am hitting some of these off of. These are good major league pitchers, but they are working on things and also competing so you don’t take that for granted.”

Mets officials were impressed with Nimmo coming off the bench last season and viewed Lagares as a better option to begin the season in center field as camp opened. But Nimmo, who has also thrived in the leadoff role, could change the script.

“Does doing what I am doing in spring training hurt? Not at all,” Nimmo said. “But they definitely want to see results when it counts during the season so I am trying to put myself in the best position to help out when it matters.

“Honestly, I think the bigger impact happened last August, last September when those were major league games, they counted and they meant something to this organization still and they wanted to see what we could do at the end there and I felt like I gained a lot of confidence from the organization during that time.”
