The Mets are in agreement with free agent closer Devin Williams on a three-year contract, reports Will Sammon of The Athletic. It guarantees more than $50MM, according to ESPN’s Jeff Passan. Jon Heyman of The New York Post suggests the deal pays $15MM salaries plus a $6MM signing bonus that includes $5MM in annual deferrals. That makes it a $51MM guarantee for the Klutch Sports client, though the $15MM in total deferrals reduce the net present value to an extent.
A second-round pick by the Brewers in 2013, Williams took a while to climb through the minor leagues as a starting pitcher. He took off after being moved to the bullpen in 2019, climbing from Double-A to the big leagues by the end of that season. Williams emerged as one of the sport’s best late-game weapons by his first full big league season. He turned in a 0.33 ERA across 27 innings during the shortened 2020 schedule and claimed the National League Rookie and Reliever of the Year Awards.
The righty continued to dominate over the next few seasons, forming a lethal back-end bullpen duo with Josh Hader. New York president of baseball operations David Stearns had a front row seat as Milwaukee’s front office leader for most of that tenure. Williams stepped into the ninth inning when Milwaukee sent Hader to San Diego at the 2022 deadline. He reeled off 36 saves in 40 tries with a 1.53 ERA to win his second career Reliever of the Year honors.
Over his first four full seasons, Williams pitched to a 1.75 ERA while striking out 40.5% of opposing hitters across 200 1/3 innings. Heading into 2024, there was a decent argument for him as the best reliever in MLB. He hit his first real setback that Spring Training, as testing revealed two stress fractures in his back. He didn’t make his season debut until shortly before the trade deadline. Williams looked every bit as dominant during the regular season, reeling off 21 2/3 frames of three-run ball with 38 strikeouts to finish the year. His season ended in heartbreak fashion, as he surrendered a go-ahead homer to Pete Alonso in the final game of the Wild Card Series against his now current team.
That wound up being Williams’ final action in a Milwaukee uniform. The Brewers flipped him to the Yankees for veteran starter Nestor Cortes and rookie infielder Caleb Durbin in advance of his final season of arbitration. The Yankees surely felt they were acquiring one of the five to ten best relievers in the sport. Williams’ results, at least, didn’t come close to those expectations.
The veteran righty had a wildly inconsistent lone season in the Bronx. He was terrible early on, giving up at least three runs in a trio of his first 10 appearances. Consecutive poor outings at the end of April led the Yankees to move him to a setup role and put Luke Weaver back into the ninth inning. Williams had one more rough appearance in early May before settling into a groove over the next few weeks. He returned to closing when Weaver landed on the injured list at the beginning of June.
Williams was lights out from that point through the All-Star Break. He gave up runs in seven of his first nine appearances of the second half, though, and the Yankees pushed him out of the closer role for good when they acquired David Bednar at the trade deadline. Williams posted a 5.06 ERA in the second half despite striking out nearly 40% of batters faced — the second-best rate among qualified relievers behind Mason Miller. He worked in a setup capacity late in the season and into the playoffs. Williams tossed four scoreless frames with four strikeouts in the postseason.
The end result was a career-worst 4.79 earned run average over 67 appearances. The Mets are placing a decent sized bet that the poor run prevention was a fluke. Opponents had a .339 batting average on balls in play when runners were on base this year. That’s easily the highest mark in Williams’ career (aside from his brief 2019 debut). He had a very difficult time stranding runners as a result. While relievers certainly need to be able to work out of tough situations, that had never previously been an issue in Williams’ career.
Batted ball metrics can be volatile, especially for relievers who only throw 60-70 innings in a season. Williams’ stuff still grades out extremely well, and he remains capable of missing bats at a level that few other pitchers can match. He struck out 34.7% of opponents behind a 16.8% swinging strike rate this past season. Those are down slightly from his usual marks but remain among the best in MLB. Among relievers with 50+ innings, Williams finished eighth in strikeout rate and 10th in whiffs.
Williams has two pitches which he has used at roughly equal rates over the past couple seasons. His fastball sits around 94 MPH and while it’s a good pitch, his standout offering is his unique “Airbender” screwball/changeup. The pitch still moves unlike any other changeup in the league, and opponents have hit below .200 against it in every full season of his career.
The underlying numbers made Williams a popular “buy-low” target among teams and fanbases. That is borne out in the contract to an extent. Williams might have been in the running for a $100MM deal had he posted another sub-2.00 ERA season. It didn’t force him to settle for a pillow contract, as he’s still being paid as a high-end reliever. Williams falls well short of the four years and $72MM which Tanner Scott commanded last winter, but he’s not far off the $46-58MM range in which closers Robert Suarez, Liam Hendriks and Raisel Iglesias have found themselves over the past few offseasons. He came up shy of the four years and $68MM which MLBTR had predicted in ranking him the second-best reliever in the class.
While an ugly walk year ERA still has some impact on a pitcher’s market, Williams is the third example this offseason of teams placing a decent amount of emphasis on stuff and whiffs in spite of that. Dylan Cease commanded a seven-year deal for the Blue Jays, while Ryan Helsley pulled $14MM annually from the Orioles on a two-year contract with an opt-out despite a brutal finish to his 2025 season with the Mets. It’s easier for clubs to place that kind of bet on pitchers coming from a different team. The Mets were never likely to bring back Helsley, and while the Yankees reportedly kept in contact with Williams’ camp this offseason, they also opted not to issue him a $22.025MM qualifying offer that probably would have kept him around on a one-year deal.
More to come.

Given the Cardinals’ struggles over the last few seasons and Helsley’s looming free agency, it was seen as a surprise that it took so long for the reliever to be traded. (In fact, the Orioles were first rumored to be interested in Helsley back
