Whatever one’s definition of valuable might be, it’s clear that Francisco Lindor embodies it. If any additional proof were required, the Mets’ star shortstop supplied it Sunday through his absence. Attempting to play through a lower-back injury, Lindor lasted all of one inning before he again had to exit.

After that, New York’s offense didn’t do much of anything in a 2-1 walk-off loss to the Phillies at Citizens Bank Park.

“Obviously, he’s a big part of the team,” designated hitter J.D. Martinez said.

The Mets received solid starting pitching in this one, as David Peterson carried a lead into the bottom of the eighth inning thanks to Tyrone Taylor’s solo homer in the top half. But Peterson cracked for consecutive doubles to start the eighth, Edwin Díaz allowed a walk-off single to J.T. Realmuto in the ninth and the Mets’ offense — minus Lindor — couldn’t do anything to counteract it.

But with the Braves losing to the Dodgers on Sunday night, the Mets departed Philadelphia still holding the final National League Wild Card spot, thanks to a tiebreaker edge over Atlanta.
