There will be no Jeff McNeil for at least the rest of the regular season, and there were no hits through the first 4 ²/₃ innings.

No problem for the Mets, who are doing everything right at the right time of the season.

The Mets silenced the Reds behind excellence from Jose Quintana — who picked up his 100th career win — and their bullpen, needing just one big inning to run their win streak to nine with a 4-0 shutout at Citi Field on a crisp Saturday that felt like fall.

A crowd of 34,048 had to wait an extra 66 minutes for the game to begin after a rain delay and had to wait about another hour and a half for a sniff of offense, but it was the Mets’ bats that eventually broke through with a four-run sixth inning.

A difficult day for the team, which lost McNeil to a fractured wrist, gave way to yet another optimistic night for its playoff odds. Carlos Mendoza’s group was awaiting the result of a late Braves game but gained a game on the Diamondbacks, now just half a game out of the second NL wild-card spot.

The Mets (78-64) are a victory away from a perfect homestand and a third consecutive sweep, finding ways to survive games in seemingly a different fashion each night.

Saturday their starter was impeccable, bullpen untouched, defense excellent and bats good enough in a strong, all-around effort.

Quintana, who is gunning for a playoff start in a crowded rotation, was terrific for a third straight turn, holding the Reds to five hits and two walks in 6 ²/₃ scoreless innings.

After a brutal stretch in August, the lefty has pitched 18 innings in three starts and let up just one earned run, his ERA sinking to 4.09.

He was not perfect Saturday, but he was when he needed to be.

Cincinnati batters went 0-for-4 with runners in scoring position against Quintana, who leaned heavily on his infield.

A diving Jose Iglesias (suddenly the everyday second baseman) smothered a sharp ground ball from Ty France that jump-started a second-inning double play; an inning later, it was Francisco Lindor (whose hitting streak ended but whose on-base streak reached 35 games) who speared a hard-hit Jonathan India ground ball in the hole and spun for a throw to second to begin another double play.

Quintana encountered trouble again in the fourth, when Tyler Stephenson reached third with one out, but the veteran bore down.

A soft tapper from Ty France got Quintana a second out before TJ Friedl’s ground out helped him escape.

The 35-year-old pitched into the seventh and left to a standing ovation, handing a bit of trouble to Adam Ottavino.

The righty entered with a runner on second and kept him there, striking out Will Benson to keep the shutout going.

The Mets’ pitching has been brilliant through this nine-game stretch, letting up 15 earned runs in 83 innings (1.65 ERA), which has taken pressure off bats that have been strong enough.

The Mets did not reach base against Reds starter Jakob Junis until there were two outs in the fourth and did not get a hit until there were two outs in the fifth.

The breakthrough, though, came in the sixth.

With Junis gone, the Mets wasted no time in attacking the opposing bullpen.

The second pitch Sam Moll threw Harrison Bader was cracked into the visiting bullpen in right-center for the go-ahead home run.

The superb center fielder has lost time recently amid a deep slump, entering play 2-for-42 in his past 21 games, many of those appearances coming off the bench.

Perhaps this was the blast that would get Bader going.

It did manage to get the Mets’ bats going.

Four of the next six hitters reached base, the significant blows an RBI single from Pete Alonso and a two-run double from J.D. Martinez, who showed off some dad strength in his second game since being activated from the paternity list.

That would conclude the Mets’ scoring, but eighth-inning domination from Danny Young (whose ERA has shriveled to 2.70) and Edwin Diaz (who has pitched in three games straight) ensured that outburst would be enough to keep a season-best win streak alive.
