No Yo.

The Mets face a two-game interleague series against the Rangers beginning Tuesday night in Texas, and Terry Collins is unsure who will serve as the DH. But it appears Yoenis Cespedes might not be an option.

“It’s a possibility, but certainly I’m hoping I hear better things tomorrow,” Collins said, referencing a progress report on Cespedes, who still is trying to move past his recent setback.

Cespedes has been on the DL with a hamstring issue, and his minor-league rehab has been limited to one game because of a quadriceps injury suffered while he ran the bases. He has yet to return to a rehab assignment.

Rene Rivera and Travis d’Arnaud have warranted time behind the plate, but for now, Collins said he will play it by ear when it comes to playing time.

“I have nothing written down where Travis has to play five days a week and Rene has to play two,” Collins said. “I think we’ll pick and choose.”

Rivera started Saturday night after d’Arnaud was in the lineup two of the previous three games. With righthander Tyler Pill starting Sunday’s series finale, d’Arnaud is expected to catch.

Inconsistent Knight

One night after Matt Harvey’s fastball faded against the Pirates, Collins acknowledged that after having surgery to correct thoracic outlet syndrome, Harvey might not rediscover his form until next season.

“We’re seeing, as you guys are, inconsistencies from time to time with the stuff,” Collins said. “And it could be something that’s caused by the fact that his arm and shoulder is still trying to come back from all the damage that was done last year.”

Harvey has pitched to a 5.43 ERA in 11 starts. He is trying to regain his form after the second major surgery of his career, with the first being Tommy John surgery.

Said Collins: “We’re learning stuff as we go here with Matt.”
