MIAMI — Jeurys Familia received an ideal low-risk opportunity to regain the Mets’ trust Sunday, but flopped.

The struggling reliever was summoned to protect a four-run lead in the seventh inning at Marlins Park and departed after retiring only one of the four batters he faced. Seth Lugo entered to bail out Familia, who had loaded the bases on a single and two walks.

“You need to pick spots [with Familia],” manager Mickey Callaway said after the Mets beat the Marlins 6-2. “We picked a spot today where we felt like if things went bad we could bail him out, which is exactly what happened. We will pick spots when we’re down to continue to get him in there. The bottom line is we have got to get him going, because we need him to pitch in games like today to be a successful team and we need him to get the outs.”

Lugo, working a rare back-to-back day, got the final two outs of the seventh before Robert Gsellman worked the eighth and ninth, surrendering a run.

Robinson Cano homered in consecutive games for the first time since Sept. 2-3, 2017. Cano had just four homers before the All-Star break, but hit two over the weekend.

“He is obviously barreling the ball up and the last couple of days he is actually getting it in the air and having some good results as far as extra-base hits and homers,” Callaway said. “It started off as barreling it up and hitting it at people and then barreling it up and getting it through some holes and now it’s translated into some homers the last couple of days.”

Amed Rosario is still a consideration to play center field this season, but Callaway said there’s no hurry for the switch to occur.

Rosario is continuing to take fly balls in the outfield during pregame.

“The challenge is to balance continuing to develop at short and trying to figure out if he’s going to be a good center field option,” Callaway said.

Jeff McNeil has a hit in 13 of his past 14 starts against Miami, with two homers and six RBIs during that stretch. He is 18-for-53 (.340) in those starts against the Marlins.
