Mets general manager Billy Eppler answered for the team’s spiral on Tuesday, when he publicly issued a vote of confidence for manager Buck Showalter and his underperforming club.

Steve Cohen is on deck.

The owner of the most expensive team in MLB history — and one of the most disappointing through a dismal first half — said he will speak publicly about the state of a club that is not close to a playoff spot.

“I will be doing a press conference [Wednesday] before the game,” Cohen wrote on Twitter before the Mets beat the Brewers, 7-2, at Citi Field. “You will get it from me straight.”

The biggest question facing Cohen will concern Showalter, who has reigned over a club that has pitched poorly, consistently run into outs on the base paths and played sloppy defense. Its overall offense also has disappointed.

Eppler publicly backed Showalter and called him “the guy to get us back on track.” According to Eppler, he and Cohen “are sharing a lot of the same feelings and disappointment amongst other things.”

Showalter heaped praise on the club’s owner.

“There’s so many things he does behind the scenes not for anybody to notice,” Showalter said of Cohen. “Little things to the stadium — somebody’s paying for that. We see the players, [but] I see a lot of other things that make me proud to be a part of his organization. He’s always looked at it like it’s the fans’ organization.

“He’s frustrated, very competitive. Trust me, very competitive man. Not afraid to ask why.

“He likes to win.”

Cohen is in his third season of control over the Mets and has said he is not prone to knee-jerk moves.

“When things get really bad, I’m not going to blow up,” Cohen told The Post’s Joel Sherman earlier this month. “I don’t think that’s the proper response.”

Francisco Lindor’s fourth-inning home run, against Julio Teheran, was the 200th of the shortstop’s career.

“It’s a blessing, especially when you can contribute to the team to win,” Lindor said. “God is good.”

Tommy Pham ripped an RBI double in the sixth inning and is now batting .350 (14-for-40) with runners in scoring position this season.

As the Mets officially called up David Peterson to start the game, they optioned righty Vinny Nittoli back to Triple-A Syracuse.

Eduardo Escobar, who was traded to the Angels last week, passed the citizenship test and became an American citizen Tuesday.

“That’s huge,” Showalter said.

Mets players had been helping Escobar prepare for the test.

“[They] asked him who the first president of the United States was,” Showalter said. “Esky had that devilish look on his face, and he said, ‘Ron Washington.’ ”
