Michael Conforto collided with Jeff McNeil on the warning track in right-center while they tried to catch up with Anthony Rendon’s RBI triple in the fourth inning of the Mets’ 7-6 comeback victory over the Nationals on Friday night at Citi Field.

It was a scary sight, since Conforto, who had the game-winning RBI single in the bottom of the ninth, has missed time because of a concussion, but he said he was OK.

“I know the trainers were concerned,’’ Conforto said. “I didn’t feel anything. I knew I got hit in the head. I was just trying to make a play. Honestly, I think I took a bad route to that ball and tried to make up for it and make a [diving] play. I felt fine, just scraped up a little bit.”

Pete Alonso homered for a fourth straight game, the first Met to do so since Curtis Granderson did it in 2016. Richard Hidalgo holds the franchise mark by hitting a home run in five consecutive games, set in 2004. Alonso also broke Lucas Duda’s mark with his 20th homer at Citi Field. Duda had 19 in 2015.

General manager Brodie Van Wagenen added both Brad Brach and Joe Panik this week as his team makes an unexpected second-half run.

“If we just take it one day at a time and not lose our focus, then we’re in a position to control our own destiny,’’ the GM said before the team’s thrilling victory.

Brandon Nimmo, who was placed on the 60-day IL to make room for Brach on the roster, remains in Port St. Lucie coming back from a bulging disk in his neck and is “going through baseball activities,’’ Van Wagenen said.

Asked if Nimmo could return next month, Van Wagenen said: “We’ll see how those baseball activities progress.’’

Callaway said Nimmo was still being looked at on a day-to-day basis and there was no date for the start of a potential rehab assignment yet.”

The Mets had their streak of scoring in the first inning in seven straight games snapped on Friday.

J.D. Davis, who hit a solo homer, has reached base in 17 straight home games. In his past 20 games overall, he’s 20-for-63 with a 1.194 OPS. What’s been most surprising about the righty hitting Davis has been his numbers against right-handed pitching. Entering Friday, Davis has an OPS of .875 versus righties as opposed to .737 over his career.
