On the verge of a four-game sweep, the Mets traded their brooms for ice-cold bats.

Wasting seven strong innings from Max Scherzer, the Mets mustered just three singles as they fell to the Rockies 1-0 on Sunday afternoon at Citi Field.

German Marquez stifled the Mets (82-47) across seven innings, allowing just one hit despite entering the game with a 5.22 ERA. Relievers Carlos Estevez and Daniel Bard (whom the Mets walked off against on Friday night) then finished off the shutout to keep the Mets from flying high into a showdown with the Dodgers on Tuesday.

“We won three games against a major league team out of four,” manager Buck Showalter said. “That’s really hard to do. I don’t care where you’re playing, who you’re playing. Coming off a tough road trip, I’m proud of the way they went after it. Faced some guys that threw the ball well. I’m not going to get bogged down in exactly — I thought the pitcher was very legit today.”

The last-place Rockies (55-74) entered Sunday allowing the most runs per game in the majors (5.51) — including 5.32 away from their hitter-friendly home park — but they held the Mets relatively in check for 13 runs across four games.

“Hats off to [Marquez], Estevez and Bard,” said Francisco Lindor, who went 0-for-4 and is now batting 0-for-17 over his last five games. “They executed. It’s part of baseball. Overall we’ve played good baseball. Today they hit better than us.”

It continued a mostly quiet week for the Mets’ offense, which has scored 17 runs over its last six games against the Rockies and Yankees.

The Mets’ only hit off Marquez came in the fifth inning on a single by Jeff McNeil, who advanced to second on a balk but was stranded there. Otherwise, Marquez allowed just two more base runners on a pair of harmless walks. The Mets never got past second base all day.

“Coming into the series, I knew [Marquez] was going to be a challenge,” Showalter said. “He’s always had a really good arm. Hard sink, really attacks, stays ahead. Slider is a tough recognition pitch late. … Never really got a lot of momentum against him. Very much like Max. Max was outstanding.”

Scherzer brought a one-hit shutout (on 96 pitches) into the seventh inning, when the Rockies finally got to him on mostly weak contact. C.J. Cron led off with a single to left field before Jose Iglesias singled on a bunt to third base, where Brett Baty was playing back. Randal Grichuk then hit a dribbler down the third-base line, where Baty charged it and backhanded the ball but had no play at first base.

With the bases suddenly loaded, Scherzer got Sam Hilliard to strike out on a slider, his 10th punchout of the day.

But Brian Serven followed with a sacrifice fly to right-center field to put the Rockies ahead 1-0.

Scherzer then got Garrett Hampson to strike out on his 112th and final pitch to end the seventh inning, leaving runners on the corners.

Once Marquez was out of the game after 102 pitches, the Mets threatened to get to Estevez in the eighth when Baty smacked a one-out single and took second on a wild pitch. But pinch-hitter Starling Marte and Brandon Nimmo struck out to end the threat.

Pete Alonso’s one-out single in the ninth inning also went to waste as Bard struck out Eduardo Escobar (who had pinch run for Daniel Vogelbach in the seventh) and got McNeil to ground out to end the game.

“Yeah, you would like to score a lot of runs, but it is what it is,” Lindor said of the offense in the four-game set. “I wish we could roll through every team out there. But as long as we win, I’m good.”
