PHILADELPHIA — Manager Terry Collins has been content to give Jose Reyes some veteran leeway. But it seems that slack may be running out. Collins said Reyes might be out of the lineup on Thursday night when the Mets begin a four-game set against the Marlins.

“We’re going to see how he’s doing,” Collins said.

In Wednesday night’s 5-4 win over the Phillies, Reyes went 0-for-4 to drop his average to .054. Deferring to the veteran’s desire to hit his way out of his season-opening slump, Collins kept Reyes in the lineup the last two games, though he was moved to the seventh slot. He responded by going 1-for-10.

“I don’t want any days off at this point, but you know, he’s the skip so I’ll take it,” Reyes said. “It is frustrating. But at the same time, I can’t put it in my head right now because we’re playing good baseball.”

Before the game, Collins said Reyes had “earned the right to fight through” his slump to start the season. But after the game, the tone had shifted.

The Mets will face lefties on consecutive days. With Reyes struggling, Wilmer Flores could easily be deployed to play third base, especially given his propensity for crushing southpaws.

Matt Harvey remains on track to make his next scheduled start on Sunday, Collins said. Harvey departed after 5 2⁄3 innings on Tuesday night with a cramp in his left hamstring . . . The Mets assigned utility man Cody Decker to Double-A Binghamton . . . David Wright has resumed throwing, though Collins said his return is still a long ways off. “We’re talking right now some baby steps, but they’re steps forward, that’s the best part,” Collins said. “I’m hoping that when he’s ready and he gets down to Florida and he starts to really move faster where it’s nice and warm and he can do some other things.”
