As the Mets tried to ride the wave of Thursday’s comeback victory over the Yankees into the holiday weekend, manager Luis Rojas saw one big part of the club that has to improve in the season’s final stretch.

“It’s the starting pitching,” Rojas said Friday before the Mets hosted the Phillies at Citi Field. “We’re looking for that consistency. [It’s] been one of our biggest adversities through this season.”

Rick Porcello answered Rojas’ Zoom call. The righthander allowed two runs in six innings and left with the score tied after retiring his last 12 batters.

But the Phillies took the lead in the seventh against Jared Hughes and held on for a 5-3 victory over the Mets, who have lost six of eight.

“The innings that Rick gave us,” Rojas said, “that was something very positive tonight, outside of us not getting the result, us not getting the win.”

Michael Conforto tied the score at 2-2 in the fifth with a two-run homer to left off Jake Arrieta. But that was all the scoring against Arrieta (3-4), who went seven innings for the Phillies, who have won 10 of 11.

With the score tied at 2 in the seventh, Hughes (1-2) — who was pitching for the fifth time in eight days — gave up a two-out double to No. 8 hitter Phil Gosselin.

Roman Quinn followed with a hard grounder up the middle that glanced off the bare hand of a diving Andres Gimenez and into centerfield for a go-ahead single.

Rojas asked Hughes for a second inning and stayed with him even after his pitch count passed 40 in the eighth. The Phillies made it 4-2 on an error by Dominic Smith, who couldn’t catch a throw from J.D. Davis on an infield single by Jean Segura, and added a run when Brad Brach hit Adam Haseley with a pitch with the bases loaded.

“We need to win every day,” Hughes said. “We show up tomorrow, we need to win. Today did not happen. We need to learn from it, shower well, come back tomorrow ready to win. Every game matters and we’ll come out tomorrow and win.”

The Mets cut it to 5-3 in the eighth on Smith’s RBI single. With the tying runs on base, Phillies manager Joe Girardi called in Tommy Hunter.

Robinson Cano greeted him with a 112-mph screamer that seemed ticketed for the rightfield corner, but first baseman Rhys Hoskins caught it with a dive for the second out. Pete Alonso fouled out to first to end the threat.

The Mets went down 1-2-3 in the ninth against new Phillies closer Brandon Workman.

On Thursday, the Mets rallied to beat the Yankees, 9-7, on Alonso’s walk-off homer in the 10th inning. It was a high point of the season, but whether it becomes the high point depends on whether the Mets can get better pitching from starters who are not named Jacob deGrom.

Porcello gave up a run in the second on an RBI single by Jay Bruce. The Phillies made it 2-0 in the third on a run-scoring line drive to right by Didi Gregorius that Conforto turned into a forceout at second when Hoskins started back to first because he thought the would-be single was going to be caught by Cano.

Porcello, who allowed three hits, walked two and struck out six, lowered his ERA from 6.00 to 5.54 with a 100-pitch outing.

The fourth-place Mets (17-22) are on the outside looking in at the NL’s expanded playoff picture. They have 21 games left before the regular season ends.

DeGrom, who starts on Sunday, has a 1.76 ERA. The rest of the pitchers who have started for the Mets have a 6.20 ERA. Of course, the Mets were supposed to have Noah Syndergaard, Marcus Stroman and Steven Matz as part of a power-packed rotation. For various reasons, that hasn’t worked out.

“We definitely have a pretty strong sense of urgency,” Porcello said. “ . . . We need to climb back into this thing . . . The sense of urgency of winning on a nightly basis is extremely important . . . We really need to go. We don’t have a lot of time.

“We’ve lost a lot of close games,” Porcello said. “Some games where we’ve really beaten ourselves. As unfortunate as that is, it’s a confidence boost because you know you’re better than these teams that you’re playing. We need to clean it up a little bit and I think we’ll be fine.”
