Anthony Rendon became the first player in MLB history to go at least 6 for 6 with three home runs and 10 RBI in Washington’s franchise record-setting 23-5 rout of the Mets on Sunday at Nationals Park.

When MASN’s Dan Kolko asked Rendon on the field after the win what it was like to be a part of a game with so many crooked numbers in the box score, the Nationals third baseman focused on the 3-hour, 37-minute game time.

“It’s definitely fun to be a part of, to be out here obviously, but it was a long game,” said Rendon, who once commented that he finds baseball too long and boring to watch when he isn’t playing.

“You don’t like talking about yourself, but I’m going to have to do this to you,” Kolko said later in the interview. “You went 6 for 6 with three home runs and 10 RBI today. You’re the 13th player in the history of Major League Baseball to have 10 RBI in a game. How do you react to that?”

“Oh, our pitching was, you know, just amazing,” the ever humble Rendon said, with only the slightest hint of a grin. “They kept them down to five runs, so, as long as we scored six, all we had to do is win.”

Yeah, and so long as the Nationals limited the Mets to 22 runs, they would salvage the final game of the series. Washington’s pitching was fine on Sunday. The bullpen was even great, with five shutout innings in relief of starter Joe Ross, who allowed all five runs in four innings. But it wasn’t historically great. It wasn’t “amazing” like Rendon’s day. (As The Post’s Jorge Castillo noted in April, Rendon’s playful evasiveness of the media is “unmatched in the Nationals clubhouse.”)

“Can I do anything to get you to comment on your offensive day today?” Kolko said with a smile.

“No,” Rendon said before retreating to the clubhouse.

The only other player in major league history with six hits, three home runs and 10 RBI in a game was Reds catcher Walker Cooper, who accomplished the feat on July 6, 1949, in a 23-4 win over the Chicago Cubs. Unlike Rendon, who had a perfect day at the plate, Cooper went 6 for 7, grounding out in his final at-bat. It’s unclear if Cooper deflected praise after the game and called attention to the 11 hits and four runs that Reds starter Ken Raffensberger scattered over nine innings.
