There are now 37 games left in the regular season for the Mets, but they have adjusted their schedules accordingly.

“It’s August, but playoffs started today,” J.D. Davis said after the Mets started a critical nine-game homestand in style with a 9-2 win over the Indians on Tuesday at Citi Field.

The Indians opened the door for the Mets when Oscar Mercado dropped Joe Panik’s pop-up in the sixth inning of a 2-2 game. Michael Conforto made them pay for the extra out, crushing a two-run homer off All-Star pitcher Shane Bieber to give the Mets the lead for good.

The Mets (65-60) then piled on with a four-run seventh inning against the Indians (74-52) bullpen to put the game out of hand and save their top relievers for another day, with every game looming large, especially in this nine-game stretch against three playoff teams. They continued their torrid run, improving to 25-10 since the All-Star break as they remain two games behind the second NL wild-card spot.

“To beat Shane Bieber in the first game to start off this homestand, to energize the fans, put ourselves in a good position to win a series against these guys is what we set out to do today,” Conforto said.

Steven Matz tamed a dangerous Indians lineup and got some help from Justin Wilson to escape a jam in the seventh inning. After getting pulled early after six innings his last time out — which led to a loss to the Braves — Matz got to start the seventh but only recorded one out before putting two runners on.

Manager Mickey Callaway called on Wilson to get out of the jam against the top of the order and he did so successfully, striking out Francisco Lindor and Mercado to keep the two-run lead intact.

“Wilson came in and got some huge strikeouts against some pretty good hitters,” Callaway said.

The Mets gave themselves some breathing room in the bottom half of the inning, with RBI singles from Amed Rosario and Panik and a two-run double from Pete Alonso stretching the lead to 8-2. Rajai Davis, called up from Triple-A Syracuse earlier in the day to face his former team, added an RBI double in the eighth.

“They’re relentless,” Callaway said. “Timely hitting, a key big hit usually starts it — Conforto’s homer — and then you get to their lesser pitchers and you add on. That’s what good teams do.”

J.D. Davis put the Mets on the board in the second inning when he clobbered a two-run home run to center field for the 2-1 lead. A tight calf had limited Davis to pinch-hitting duty over the weekend in Kansas City, but he cleared pregame testing and looked just fine rounding the bases.

The Mets were on the wrong end of a fielding error earlier in the night, when Todd Frazier could not backhand a ground ball from Yasiel Puig. Jose Ramirez and Jason Kipnis followed with back-to-back singles up the middle, the second scoring Puig to tie the game 2-2. Matz worked himself out of trouble, though, leaving runners on the corners by striking out Bieber with a full count.

The offense and bullpen took care of the rest as October has arrived early to Citi Field.

“We have to have that playoff mentality, that playoff atmosphere that every game counts,” J.D. Davis said. “Especially [with] the hole that we dug ourselves into. I think the elephant in the room is we got a lot of home games, but a lot of games against playoff teams. This is our playoff time. We have to play well and we have to come out ready to play.”
