PHOENIX — Brandon Nimmo and Asdrubal Cabrera put an exclamation point on an improbable rally to conclude Father’s Day in the desert for the Mets.

Almost roadkill, on the verge of another maddening defeat, the Mets assembled a rally that ranked as maybe their best of 2018, injecting at least some hope into a team gasping for relevancy.

The ninth-inning party culminated with Nimmo stroking a two-run, go-ahead homer against Brad Boxberger and Cabrera following with an insurance blast in a 5-3 victory over the Diamondbacks at Chase Field.

“I think we have been waiting for a big hit to happen,” Nimmo said. “I don’t know what it means for the future, but for right now to get two wins in a row against a good Diamondbacks team, that’s awesome.”

The Mets (30-38) have consecutive victories for the first time since May 21 and will have a little extra energy as they prepare to begin a four-game series in Colorado on Monday.

“I was kind of thinking before this game from ‘Major League’ where they are like, ‘You can win two games in a row, it has been done before, it’s called a winning streak,’ ” Nimmo said. “I was kind of thinking that, it had been a while, so for us to get that second win on a big hit, that’s really good for our positivity.”

Jose Reyes’ two-out bunt single — that should have been allowed to roll foul by catcher Alex Avila — started the comeback before Jose Bautista delivered an RBI double that pulled the Mets within 3-2. Nimmo followed with a rocket, giving the Mets more than three runs for the second straight day — after 11 straight games in which they had failed to surpass that threshold.

Cabrera, who entered in a 5-for-55 (.111) slump, coat-tailed with a blast that gave the Mets their margin of victory.

“That’s something we were doing early on, which feels like three years ago,” manager Mickey Callaway said of the comeback.

The comeback exonerated Jay Bruce, who had a brutal 0-for-4 performance with three strikeouts, leaving five runners on base, in his return to the lineup after missing three games with a sore upper buttocks.

Robert Gsellman pitched a scoreless ninth for the save after Jeurys Familia, in his return from the disabled list, surrendered a run in the eighth that put the Mets in a 3-1 hole.

Nimmo finished the day 3-for-5 and scored the Mets’ first run after leading off the game with a double against Clay Buchholz.

“We want our young guys to come up here and blossom, and [Nimmo] has done a tremendous job,” Callaway said. “He is a player that has many strengths and he always gives himself a chance because his last resort is to draw a walk. Pitchers know that and they end up having to groove a pitch and he does some damage.”

Bruce faced a big test in the sixth, when lefty reliever Andrew Chafin entered to face him with two outs and runners on second and third base. Bruce went ahead 3-0 in the count before striking out for the third time in the game.

Familia surrendered a bloop RBI single to Jake Lamb that gave the Diamondbacks their final run. Familia, who had missed the previous 10 days with a sore shoulder, escaped further damage after loading the bases.

Zack Wheeler kept the Mets in the game by allowing two earned runs on three hits with two walks and eight strikeouts over six innings. It was a rebound performance from the right-hander, who surrendered six earned runs over 5 ²/₃ innings in Atlanta last week.

Wheeler retired the first 10 batters he faced before denting in the fourth. David Peralta stroked an RBI double that tied it before Ketel Marte’s RBI groundout placed the Mets in a 2-1 hole. Paul Goldschmidt walked to begin the rally, and Lamb slashed a single for the Diamondbacks’ first hit.

In the end, Wheeler was left as a witness to a spirited Mets victory.

“We needed a hit and [Nimmo] came through for us at the right time,” Wheeler said. “He’s becoming a very good player for us and it’s nice to see.”
