NEW YORK -- Although the Mets are open to dealing closer Edwin Díaz, they’re not interested in buying high and selling low.

Instead, multiple sources said that the Mets have set such a sky-high price for Diaz that while they’re willing to entertain offers, they’re unlikely to complete a trade before the July 31 Deadline. Diaz, whom the Mets acquired with Robinson Canó in a seven-player deal in December, remains under team control for three more seasons.

“I don’t really have a reaction to it,” Diaz said of recent trade rumors involving his name. “My job is to go on the mound every day, whenever they call me to do my job. I’m happy to be here, so it’s out of my control.”

Like Cano, who hit three home runs on Tuesday, Diaz has been better since the All-Star break in a small sample. He has thrown five scoreless innings since the break, after posting a 5.50 first-half ERA and blowing four of his 23 save opportunities.

Given the fickle nature of relievers, rival teams eye Diaz as an easy reclamation project -- the type of player who could go elsewhere and dominate down the stretch. But the Mets don’t want to sell him for anything less than his full sticker price; to acquire Diaz and Cano last winter, they had to give up two of their best prospects in Jarred Kelenic and Justin Dunn, as well as assume the bulk of the $120 million remaining on Cano’s contract. Selling Diaz for less just seven months later would be admitting defeat on a player with obvious untapped upside.

So most likely, Diaz will remain in-house. That goes also for fellow relievers Seth Lugo and Robert Gsellman, according to sources, as both figure to be key parts of the Mets’ 2020 bullpen. General manager Brodie Van Wagenen is on record saying he’s unlikely to trade anyone who has multiple years of team control remaining.

Essentially, that whittles the Mets’ realistic trade candidates down to starting pitchers Zack Wheeler and Jason Vargas, and third baseman Todd Frazier, all of whom could move by July 31. Diaz, meanwhile, says his mind won’t be on trade rumors when he takes the mound.

“Nothing breaks my focus when it comes to that,” he said. “Whenever I’m on the mound, I’m only focused on pitching at that point. There’s nothing that can distract me from that situation.”

“We try to make sure those things don’t become a distraction, because there are trade rumors all the time,” manager Mickey Callaway said. “People want good players, and we have a lot of good players. I’d want some of our pitchers and position players, too.”

Fretting about trade rumors is something Diaz used to do, but no longer. Now that he has been traded once, he doesn’t worry as much about what the future holds.

“It actually has a little bit more of a calming effect for me,” he said. “When I was in the Minors back in Seattle, I would always come up in rumors that they were going to trade me. But now I’m just calm. ... Whatever happens, happens.”
