Edwin Diaz’s status appears safe.

After hinting Seth Lugo could steal the closer’s role, and then using Diaz in a non-save situation in the opening win of Monday’s doubleheader against the Marlins at Citi Field, manager Mickey Callaway shot down speculation that a switch had been made.

“We brought in the guy that’s gonna be our closer, and has been our closer, in a situation where you normally bring in your closer,” Callaway said. “And he did a good job.”

However, it was Lugo who saved the second game, pitching the eighth and ninth innings for a six-out save. It was his second save of the season.

In Robinson Cano’s absence because of a torn hamstring, Jeff McNeil started at second base in the first game, and Luis Guillorme started the nightcap after being recalled from Triple-A Syracuse.

Guillorme, 24, hit .202 with two extra-base hits in four previous stints with the Mets (52 games), but batted .307 with seven homers in 69 games at Syracuse this season, helping the strong defender earn the nod over Dilson Herrera and Ruben Tejada, who is hitting .343 in Triple-A.

“We like the left-handed bat,” Callaway said. “I think that his ability to touch the ball, put together a pretty good at-bats, even against guys with really good stuff is gonna help us out. And he can play all three [infield] positions, and play them pretty well. We felt like he was the best fit at this point, and we felt like he’s gonna put together competitive at-bats for us.”

Sources told The Post the Mets were open to potentially bringing back Asdrubal Cabrera, but the recently released 33-year-old signed with the Nationals on Monday.

Callaway said Dominic Smith (foot), Brandon Nimmo (neck) and Jed Lowrie (calf) all remain without timetables in their respective recoveries.
