The New York Mets and reliever Devin Williams agreed to a three-year, $51 million deal, league sources told ESPN’s Jeff Passan on Monday night, giving the club a replacement for Edwin Diaz should the All-Star closer sign elsewhere.
The contract has no opt-outs or options but includes a $6 million signing bonus spread over the three seasons.
Williams will bolster the back end of a bullpen that the Mets are determined to substantially improve this winter. The question is whether he will be used as a setup man or a closer.
Williams’ role depends on whether the Mets re-sign Diaz, who opted out of his contract last month and is considered the top free agent reliever this offseason. The addition of Williams does not erase the possibility of a reunion with Diaz, and the Mets remain interested in bringing him back, sources told Passan.
Williams, 31, hit free agency after his lone season with the New York Yankees. Acquired last December from the Milwaukee Brewers for pitcher Nestor Cortes and National League Rookie of the Year finalist Caleb Durbin, Williams struggled to a career-worst 4.79 ERA over 67 appearances for New York. But underlying metrics — including a 2.68 FIP, a .195 expected batting average against, and elite strikeout, whiff and chase rates — suggest the bloated ERA is misleading.
He saved 18 games in 22 chances for the Yankees, but despite entering the season as the designated closer, he shared the role for most of the season after his rough start to 2025. Williams recorded four scoreless outings during the Yankees’ postseason run, but David Bednar earned both of New York’s playoff saves.

Before joining the Yankees, Williams was a premier back-of-the-bullpen pitcher during his six seasons with Milwaukee, first as a setup reliever for star closer Josh Hader and then as Hader’s replacement in the role.
After winning the NL Rookie of the Year in 2020 — when he posted a 0.33 ERA over 22 outings — Williams was named to two NL All-Star teams. During the three seasons before being dealt to the Yankees, Williams went 15-7 with 65 saves and a minuscule 1.66 ERA.
Williams has had an unorthodox style as a closer. Despite a fastball velocity below the big league average, he flourished thanks to one of the game’s best changeups, an offering so distinct that it acquired a nickname — “The Airbender.”
Now, Williams will be reunited with Mets president of baseball operations David Stearns, who was in that role for the Brewers for Williams’ first four seasons in Milwaukee.
Williams’ agreement with the Mets was first reported by The Athletic.
