Carlos Mendoza plans for Mets’ five-man rotation to stick — for now

Carlos Mendoza said Saturday the Mets would stick with a five-man rotation the next time through, leading into Thursday’s off-day, as opposed to adding another starter for a turn.

So David Peterson will start on regular rest for a fourth time this season on Wednesday, something he’s had mixed results with this season.

In three outings on four days’ rest, the left-hander has a 7.71 ERA. When on five days’ rest, Peterson has put up a 2.35 ERA in 14 starts.

Peterson, like Clay Holmes, has already pitched more innings than any other season in his MLB career, and Mendoza said they will try to find how to get the most out of their starters.

Holmes has similar splits to Peterson, with a 3.32 ERA with an extra day’s rest and 4.91 ERA without.

“Those are conversations we have,’’ Mendoza said of altering routines to get better results when they don’t go with a sixth starter.

“Clay, the last time he pitched against the Padres on regular rest and we saw the results,’’ Mendoza said of Holmes’ latest rough outing. “We’ll continue to monitor it. We feel good about it. They understand that at some points throughout the year, you’re gonna have to take the ball on regular rest. [Peterson] has done it. We’re not concerned at all.”

And Peterson added that as long as he’s given enough time to prepare, he’s “good with either” setup.

He also noted his shaky numbers on regular rest are mostly the result of two poor outings, with the other being fine.

“They might have just been bumps in the road,’’ Peterson said.

Cedric Mullins got his first start for the Mets in Saturday’s 12-6 win after coming over from the Orioles at the trade deadline, leaving Tyrone Taylor on the bench.

It’s something Taylor may have to get used to, especially in the midst of an 0-for-18 streak, with a .467 OPS in his previous 68 games after showing some life at the plate over the first month of the season.

He’s been bad versus right-handers and worse against lefties this season, and said he would try to find ways to contribute even in a smaller role.

“I understand the situation, and I’ve been in it multiple times in my career,’’ Taylor said. “Any time I’m on the field, I’ll do my best to help the team win, whether it’s playing small ball or defense.”

Taylor is bothered more by his lack of productivity than a potential lack of playing time.

“I’m thankful to be here,’’ Taylor said. “I was just thinking to myself sitting here, there aren’t many guys who could have a .500 OPS and still be in the big leagues. I want to turn things around there. It’s definitely frustrating. I just want to be better for the team.”

The Post’s Joel Sherman reported the Mets designated Rico Garcia for assignment following the game Saturday. Garcia pitched the ninth and the Mets figure to need a fresh arm for Sunday. … Francisco Alvarez was back in the lineup on Saturday for the first time since he was removed from Wednesday’s game in San Diego after being struck in the helmet by a foul tip. He went 1-for-4 with a single and a run scored.
