NEW YORK — Within the first few minutes of a news conference after the New York Mets’ 7-6 walk-off win over the New York Yankees on Sunday, Mets manager Carlos Mendoza said the same word four times.Fight.For weeks, Mets officials kept saying that they believed in their team because of “the talent in the room.”The reality is that turning things around requires more. Last season, talent wasn’t enough. This season, injuries have stripped the Mets of much of their talent. Outside of maybe the specific case of Bo Bichette, the task for the Mets is no longer about playing to their talent level.It’s about resilience.The Mets trailed by three runs heading into the ninth inning Sunday. The Mets had been 0-91 when trailing after eight innings since the start of last season. It was the longest such streak in the major leagues.“That’s impressive, right? That’s hard to do,” Mendoza said with a smile. “Baseball, it’s hard to explain at times. Now, we continue to come back in games. We get down, we get punched in the face, we get back up. Today was a perfect example.”It was the Mets’ best win of the season. Tyrone Taylor’s three-run home run in the ninth inning tied the score at 6-6. Carson Benge’s chopper with the Yankees’ infield drawn in and featuring five defenders scored Marcus Semien from third base to win it in the 10th. The four-run deficit they erased (they trailed 5-1 heading into the bottom of the sixth inning) represented their biggest comeback of the season.It was the Mets’ best week of the season. In their homestand, they went 5-1. Each of their five wins featured a comeback.
