2) Devin Williams
While the Mets are expressing interest in Williams, this only really works unless he's paired with Edwin Diaz. They shouldn't be relying on Williams to be their closer and live up to Diaz after the nightmare season he had with the Yankees; however, Williams has still proven himself to be one of baseball's better relievers.
His offspeed stuff stayed nasty in 2025, and he was still successful in getting batters to chase (35%, 97th percentile in MLB) and strike out (34.7%, 97th percentile). His xERA was 3.09 and his xBA was .195, which suggests that much of his struggles may have been a point of bad luck or poor defense behind him.
The Mets shouldn't sign Williams to overtake the role of Diaz, but he can be an effective eighth-inning guy or can close a game out if Diaz is unavailable. Williams may be seeking a more consistent closer role elsewhere and should not be ruled out of that role heading into 2026, but the Mets should still take a crack at him while trying to retain Diaz. Still one of baseball's better relievers, perhaps a crosstown move is what Williams needs to get his mojo back.
