While Wilmer Flores hit well during his spell as the Mets’ starting third baseman, the team’s reacquisition of Jose Reyes leaves Flores’ role going forward uncertain.

Flores had hit .315 since June while filling in for the injured David Wright, but Reyes started at third in his season debut Tuesday night. Flores started at second to give Neil Walker the night off, Terry Collins said.

When asked before the game about taking Flores out of a starting role, Collins said “I didn’t. He’s playing tonight, he’s playing tomorrow, he might play the next day.”

Collins said there’s a “good shot” Flores would start at first base Wednesday, and added “we’re going to try to keep his bat in the lineup against lefties.” Flores is hitting .293 against lefties and .243 against righties this season.

“You have to get used to it,” Flores said of the utility role. “I want to be out there as much as I can, and to be able to do that, I have to [play multiple positions].”

D’Arnaud honors Peyton Manning

Peyton Manning retired from football earlier this season, and you can count Travis d’Arnaud among those trying to carry on the quarterback’s legacy.

Beginning Tuesday, d’Arnaud, who said he is a Colts fan, will wear No. 18, after ceding No. 7 to Reyes. Manning wore the same number during his career with the Colts and Broncos, and d’Arnaud said the decision to wear the number was “for him.”

To make room for Reyes on the 25-man roster, the Mets optioned shortstop Matt Reynolds to Triple-A Las Vegas.

“He played very, very well,” Collins said. “We just don’t have enough spots. He was the guy that we thought ‘he’s got to go play,’ so when he comes back, he’s ready to resume what he did when he got here.”
