NEW YORK — With a laugh on Sunday, hours before the New York Mets played the final game of their nightmare first half, Francisco Lindor declined to discuss his trade veto power.It is fair to wonder, however, whether there were circumstances in which he’d waive his rights. As a 10-year veteran who has played the last five consecutive years with the same team, Lindor holds veto power over any potential trade. By trading or moving on from other former core players, the Mets front office has demonstrated that sentimentality won’t interfere with its idea of what’s best for the organization.Still, New York Mets owner Steve Cohen told the New York Post recently that he didn’t see Lindor going anywhere. And even if the Mets ever wanted to move Lindor, his contract presents significant challenges. Beyond this season, Lindor, 32, is owed $160 million through 2031.So let’s assume Lindor is on the Mets’ 2027 team, a topic he freely engages with. When asked about his outlook on the club’s future under president of baseball operations David Stearns’ front office, the five-time All-Star said, “I’m very confident. I honestly thought they put a good team together. It’s just, we didn’t play. I didn’t perform. That’s what it comes down to.”With their postseason hopes down to 0.9 percent, per FanGraphs, the Mets (40-57) are set to enter evaluation mode for 2027. In a way, that sets them apart from their struggling peers. And because of their roster construction, the Mets need to see improvement from their veterans in the second half.That starts with Lindor.In his best offensive game since returning from the injured list on June 24, he went 2-for-4 in the Mets’ 3-2 loss to the Boston Red Sox on Sunday with a double and a home run. Defensively, however, Lindor made an error in the ninth inning on a routine grounder that could’ve led to a game-ending double play.
