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.

The Orioles signed closer Ryan Helsley to a two-year contract Monday, continuing the remaking of their beleaguered pitching staff with one of the most sought-after relievers on the free agent market.

Sources told ESPN’s Jeff Passan that the deal is for $28 million and includes an opt-out after the first season.

While multiple teams sought to sign Helsley as a starter, the 31-year-old right-hander chose to remain in the role that made him a two-time All-Star and will hand him the ninth inning for the Orioles while retaining the ability to reach the open market after 2026.

Helsley, whose deal is pending a physical, is the second bullpen addition of the winter for Baltimore, which reacquired right-hander Andrew Kittredge from the Cubs after dealing him to Chicago at the trade deadline. With a moribund pitching staff, the Orioles went 75-87 and finished in last place in the American League East after consecutive postseason berths.

Orioles president of baseball operations Mike Elias trawled the free agent market for a late-inning option and landed on Helsley, who over his seven-year career has a 2.96 ERA in 319⅔ innings with 377 strikeouts, 133 walks and 105 saves.

Among the lowest points were the final two months of Helsley’s 2025 season, when, following a deadline deal from St. Louis to the New York Mets, he posted a 7.20 ERA and allowed 36 baserunners in 20 innings. Coming off an All-Star showing for St. Louis in 2024, which included a National League-leading 49 saves and a 2.04 ERA, Helsley saved 21 games with a solid 3.00 ERA for the Cardinals before the deadline, when he was sent to the Mets for three prospects.

Acquired to deepen a New York bullpen anchored by closer and fellow free agent Edwin Diaz, Helsley struggled badly during his time with the Mets. He blew saves in three straight appearances in mid-August and spent most of the past month working in low-leverage situations as New York collapsed down the stretch and missed the postseason.

Baltimore saw more noise than signal in Helsley’s downturn and is banking on Helsley’s stuff — which pitch-quality metrics rate as some of the best in the game — returning him to dominance. Helsley deploys one of baseball’s hardest fastballs, which averaged 99.3 mph in 2025, according to Statcast, ranking in the 99th percentile of all pitchers.

With incumbent closer Felix Bautista expected to miss the 2026 seasons following rotator cuff and labrum surgeries in August, the Orioles entered the winter with only right-hander Yennier Cano and left-hander Keegan Akin as veteran bullpen options. Beyond Helsley and Kittredge, Baltimore could add another reliever, sources said. The Orioles’ need for pitching help isn’t limited to their bullpen, either. Following the trade of Grayson Rodriguez to the Los Angeles Angels for left fielder Taylor Ward, Baltimore continues to pursue starting-pitching options to join left-hander Trevor Rogers and right-hander Kyle Bradish at the top of their rotation, sources said.

A fifth-round pick out of Northeastern State in Oklahoma, Helsley was a full-time starter throughout the minor leagues until he joined the Cardinals’ big league roster. From 2022 to ’24, he was arguably the most valuable reliever in the NL, alongside right-hander Devin Williams, a free agent with whom the Orioles spoke as well.

The Penn State coaching search, which has gone quiet in the past few weeks, has focused on BYU coach Kalani Sitake, sources told ESPN on Monday.

The sides have been in discussions, but sources cautioned that no deal has been signed yet. The sides have met, and there is mutual interest, with discussions involving staffing and other details of Sitake’s possible tenure in State College.

No. 11 BYU plays Saturday against No. 5 Texas Tech in the Big 12 title game, with the winner securing an automatic bid in the College Football Playoff. On3 first reported Sitake as Penn State’s top target.

Sitake has been BYU’s coach since 2016, winning more than 65% of his games. He guided BYU to an 11-2 mark in 2024, and the Cougars are 11-1 this year. This is BYU’s third season in the Big 12, and the transition to becoming one of the league’s top teams has been nearly instant.

Penn State officials were active early in their coaching search, which included numerous in-person meetings around the country. That activity has quieted in recent weeks, sources said, even as candidates got new jobs and others received new contracts to stay at their schools.

BYU officials have been aggressive in trying to retain Sitake, according to sources, and consider it the athletic department’s top priority.

BYU plays a style that’s familiar to the Big Ten, with rugged linemen and a power game that’s complemented by a creative passing offense in recent years.

This week, Sitake called the reports linking him to jobs “a good sign” because it means “things are going well for us.”

James Franklin was fired by Penn State in October after going 104-45 over 12 seasons. Franklin’s departure came after three straight losses to open league play. He led Penn State to the College Football Playoff semifinals in January 2025.

Sitake has won at least 10 games in four of his past six seasons at BYU. After going 2-7 in conference play while adjusting to the Big 12 in 2023, BYU has gone 15-3 the past two years and found a quarterback of the future in true freshman Bear Bachmeier.

Sitake has no coaching experience east of the Mountain Time Zone. He was an assistant coach at BYU, Oregon State, Utah, Southern Utah and Eastern Arizona.

Sitake, who played high school football in Missouri, played at BYU before signing with the Cincinnati Bengals in 2001.

He is BYU’s fourth head coach since his mentor, LaVell Edwards, took over in 1972.
