NEW YORK — So that’s what the 2021 Mets are supposed to look like.

Hampered early in April by a disjointed schedule, five postponed or suspended games, an offense that froze like a blue screen with runners in scoring position, a bullpen that struggled to finish off games, two top-of-the-order hitters hardly producing and a fan base growing weary of it all, the Mets on Tuesday became better versions of themselves in a doubleheader sweep of the Phillies at Citi Field.

In so doing, they moved above .500 for the first time in the young season.

Hours after stealing a 4-3 win in extra innings in the day half of the doubleheader, the Mets constructed their most complete game of the season in a 4-0 nightcap win over the Phillies, with Marcus Stroman completing six shutout innings. Stroman was electric throughout, retiring the first nine batters he faced and inducing two double plays.

The Mets scored all the runs they would need off Phillies ace Aaron Nola in the fourth, plating their first on a Jonathan Villar double and the other two on a Brandon Nimmo single.
