​With no off day for the Mets until the All-Star break, New York has announced the addition of right-hander Dan Hammer to the major league roster ahead of Thursday’s series finale against the Kansas City Royals, per MLB.com’s Anthony DiComo. Hammer, 28, has logged 27 appearances across the Double-A and Triple-A levels this season, posting a 2.16 ERA and a 1.26 WHIP while recording 38 strikeouts over 33.1 innings. Notably, his work with Syracuse has been particularly strong, as he owns a 1.77 ERA over 17 outings for the Triple-A club.
Hammer’s path to the big leagues has included several stops in the minor leagues. Before signing a minor league contract with the Mets this spring, he spent six seasons within the Orioles and Rays organizations. He was originally drafted by Baltimore in the 13th round of the 2019 MLB Draft, and later found a new opportunity with Tampa Bay when he was selected in the 2025 Rule 5 Draft. If Hammer appears in a major league game, it will mark his big league debut.
Which roster spot Hammer will fill remains to be determined. The Mets recently recalled Xzavion Curry from Triple-A on Wednesday, and Curry threw 22 pitches in his one-inning stint during the Mets’ victory, suggesting that Curry could be the corresponding move or might retain his spot in the bullpen. The official recall and any roster maneuvering are expected to be finalized shortly before the Mets wrap up their series at 1:10 p.m. on Thursday.
The timing of Hammer’s call-up is notable for Mets fans following a relatively grueling stretch of the schedule, as the team navigates a packed slate with limited downtime before the All-Star break. If Hammer makes his debut in Thursday’s series finale, it will add an intriguing rookie storyline to a Mets club that has leaned on a mix of seasoned relievers and emerging arms throughout the season. His performance at the minors, highlighted by a strong 2.16 ERA across 27 appearances and a sub-2.00 ERA with Syracuse, suggests the potential for a useful bullpen option as New York shifts gears in the second half of the season.
In sum, Dan Hammer’s recall represents another chapter in the Mets’ ongoing quest to bolster their pitching depth from the farm system. While the exact role and placement on the roster are still being finalized, the upcoming decision will impact the late-inning workload for Thursday’s finale and could shape the rotation and bullpen plans as New York readies for the stretch run. Fans will want to watch closely as the club makes the official move and confirms the roster configuration in the hours leading up to first pitch.
