Series victory over the Rockies, check. MetroCard to face the Yankees, check. Respectability for the Mets? TBD.

These next two games could serve as that barometer, with .500-and-above again in sniffing distance for manager Mickey Callaway’s bunch following a 6-1 beatdown of the Rockies on Sunday at Citi Field to win a second straight series.

Next stop, The Bronx for two games in the first leg of this season’s Subway Series.

“I think we have a real good chance going in there,” Pete Alonso said. “It’s going to be an awesome environment, but hell, this is what it’s all for.”

Dominic Smith was aware the Yankees had handled the Mets since he became cognizant of the Subway Series in 2017. For further clarity he was told the Yankees have won seven of 10 against the Mets over those two seasons.

“That’s perfect, thanks for reminding me and giving me some real numbers with that so I’m really excited now for sure,” Smith said.

“The fans are going to come out and it’s a battle for the city. We want the Empire State Building to be blue and orange at the end of the night.”

Noah Syndergaard scintillated on Sunday, firing a one-hitter over seven innings, as the Mets improved to 19-11 at home. The right-hander allowed a single against the shift in the second to Nolan Arenado (the ball hit Adeiny Hechavarria’s glove) and was then close to untouchable — Ryan McMahon walked in the fifth for the Rockies’ only base runner over the final five innings.

Syndergaard, who had allowed at least three runs in each of his previous three starts, used his 98-mph heat as his put-away pitch, finishing with seven strikeouts and two walks over 98 pitches. Callaway indicated he removed Syndergaard after the seventh in part because the pitcher had become fatigued covering first base twice the previous inning.

The outing was Syndergaard’s strongest since May 2, when he fired a shutout and homered for the game’s only run in a victory over the Reds.

“This was an encouraging outing because that’s a real good team over there,” Syndergaard said.

Todd Frazier lofted a three-run homer in the first inning against Jeff Hoffman that gave the Mets all the cushion they needed. But Frazier wasn’t finished, delivering an RBI double in the fifth that extended the Mets’ lead to 5-0.

It continued a torrid stretch for the veteran third baseman, who is 27-for-78 (.346) over his past 23 games.

J.D. Davis followed Frazier’s double in the fifth with an RBI triple. Davis has been among the Mets’ best performers this season at Citi Field, where he is hitting .333. Carlos Gomez drove in the Mets’ other run, with an RBI single in the fourth.

Jason Vargas and Zack Wheeler will now be asked to keep the Mets competitive against a Yankees lineup that is missing marque players such as Aaron Judge, Giancarlo Stanton and Dellin Betances, but is still producing enough to keep the team first in the American League East.

Two weeks ago the idea of Vargas opening a Subway Series would have seemed unappealing to the Mets. But the veteran left-hander is pitching at his highest level in two seasons, following a one-run gem over seven innings at Dodger Stadium with a shutout against the Giants last week.

“He’s riding high on confidence, he’s executing pitches, he’s working hard,” Callaway said. “And that always gives you a chance to have a real good game.”

Smith is ready to receive both sides of it from the fans.

“We are going to hear a lot of boos and we are going to hear a lot of cheers,” he said. “It’s going to be a crazy couple of games and we wish we could play them more.”
