Jeff McNeil was back at second base on Thursday night, with the Marlins starting right-hander Roddery Munoz.

And with the Padres scheduled to go with three right-handers when they come to Citi Field, the left-handed McNeil should be expected to see some more starts over the hot-hitting Jose Iglesias, with Carlos Mendoza making it clear Thursday.

“I’ll continue to say, ‘Jeff McNeil is our second baseman,’ ” Mendoza said before McNeil went 0-for-3 in the Mets’ 3-2 comeback win over the Marlins at Citi Field. “He’ll continue to get playing time. Iglesias has been great, especially against lefties. [Iglesias’] defense, his energy, talking to players, has been great. We need Jeff McNeil.”

McNeil sat for four straight games, all versus lefties, before he returned to the lineup against a right-hander when the Mets faced the Phillies in London.

He responded with two hits, but then went 0-for-4 in Wednesday’s win over Miami, when he batted ninth for the first time in his career.

“He wants to help the team,” Mendoza said. “He was frustrated that a couple calls didn’t go his way. He’s a competitor and he wants to help. This is a good hitter — a good player — that’s gotten off to a slow start.”

Mendoza noted that McNeil was among the players that took early batting practice Thursday, along with Francisco Alvarez and Pete Alonso.

And Mendoza said he saw some promising signs Wednesday despite the results.

“I thought, even with the oh-for, the way he played defense was good to see,’’ Mendoza said. “He will get opportunities. We need these guys to get going because he’s a really good player.”

With Edwin Diaz returning from an IL stint, the Mets chose to option left-hander Danny Young instead of Dedniel Nunez, who impressed Wednesday with 2 ¹/₃ scoreless innings against Miami.

Mendoza said the decision “was not an easy one.”

The Mets went with the right-handed Nunez because of his “dominance” and Mendoza indicated he could pitch in bigger spots.

“He can go multiple innings and pitch high-leverage,’’ Mendoza said.

Young’s departure leaves the Mets with just one lefty in their bullpen, Jake Diekman, so they will continue to rely on some right-handers against lefties.

Sean Reid-Foley has been among the righties that’s handled lefties well.

Nunez, Young and Reed Garrett still have minor league options, as do Grant Hartwig and Josh Walker — both already at Triple-A Syracuse.

The streaky Starling Marte entered Thursday on a tear, with three straight multi-hit games.

He went 0-for-2 with a walk in the win.

And in his previous nine games, the right fielder was 16-for-34 with four extra-base hits and an OPS of 1.232.

During that stretch, Marte also had seven multi-hit games.
