Mets Gutted Their Bullpen at the Deadline. Now They're Auditioning Minor Leaguers for 2027.

The Mets are not pretending 2026 is salvageable. What they're doing instead is running a seven-week job interview for next year's roster, and the bullpen is Exhibit A.

At the trade deadline, David Stearns, the Mets' President of Baseball Operations, dealt four of the team's top five relievers: A.J. Minter, Brooks Raley, Luke Weaver and Huascar Brazoban. In return, according to Sports Illustrated, the Mets got seven minor league prospects. That's a lot of future assets for a lot of present bullpen depth walking out the door.

What's left in high-leverage relief is closer Devin Williams, who signed a three-year deal that runs through the 2028 season, per SI. Everyone else is in an audition.

The Mets moved fast to fill the vacated roster spots. Will Sammon of The Athletic reported the club is adding outfielder Cristian Pache and pitchers Dedniel Núñez, Jefry Yan, Nate Lavender, Chayce McDermott and Xzavion Curry, according to MLB Trade Rumors. Pache and Lavender both need to be added to the 40-man roster to make it happen.

Lavender's path here is a strange one. The Tampa Bay Rays took him in the Rule 5 draft in December 2024, months after he'd had UCL surgery. He never appeared in a game for Tampa in 2025 and was returned to the Mets after the season, according to MLB Trade Rumors. Now, at 26, he's getting his major league debut look. He's thrown 43 innings at Triple-A this year with a 3.77 ERA, a 40.2% strikeout rate and a 9.2% walk rate, numbers MLB Trade Rumors says look even better than his surface ERA once you account for a .354 batting average on balls in play against him.

He's still got a full slate of options, meaning the Mets can option him back to Syracuse without much roster risk if he struggles.

Pache, 27, was once a top prospect in baseball but has never hit at the major league level, posting a career .181/.243/.275 line in 610 plate appearances, according to MLB Trade Rumors. His calling card now is speed and defense: an 80th-percentile sprint speed the last time he played in the majors, in 2024, and strong outfield defensive metrics including 15 Outs Above Average across parts of six minor league seasons. He's not being auditioned as an everyday bat. He's a pinch-runner and late-inning defensive option.

The most talked-about name in the bullpen mix is Dedniel Núñez, who Sports Illustrated notes was activated off the injured list this month after missing significant time in each of the past two seasons with elbow problems, including Tommy John surgery in 2025. If Núñez can stay healthy and show his old form, he becomes a genuine building block for 2027. If he breaks down again, that's an answer too.

Then there's Kodai Senga, whose situation is the most consequential financial question in this whole exercise. Rising Apple notes Senga is now getting leverage innings out of the bullpen, and with $15 million owed to him next season, the Mets need him to prove he's a trustworthy seventh-inning arm. Anything less makes that contract a sunk cost the front office will have to manage around.

On the position-player side, Rising Apple points to Brett Baty as another player with something to prove in these final weeks, given his positional versatility and inexpensive contract. The site is blunt that sending him to the minors again would be pointless at this stage, calling him a Triple-A-caliber player who needs to show more against big league pitching, not against Triple-A arms.

Stearns built his reputation identifying and developing relievers during his time running baseball operations in Milwaukee, according to Sports Illustrated. That's why the front office felt comfortable selling off four established arms for seven prospects instead of trying to keep the band together for a lost season. It's a bet on player development and prospect capital over incumbency, one that will be graded almost entirely on what happens in 2027, not this year.

The open question is straightforward: which of these six new additions, plus Núñez and Senga, actually stick. The Mets have roughly seven weeks of games left to find out, and four 40-man roster vacancies still unfilled gives Stearns room to keep testing names before the season ends.
