The New York Mets added experienced left-handed pitcher to their organization on Monday, acquiring the 31-year-old from the Detroit Tigers in exchange for cash considerations. The club announced the move on X as it continues to search for pitching depth during a difficult 2026 campaign.
Although Seelinger has yet to appear in a Major League game, he has consistently produced at the Triple-A level. Pitching for Triple-A Toledo this season, he posted a 3.89 ERA across 27 relief appearances while continuing to show the reliability that has kept him on the radar of big league organizations. According to Chris McCosky of the Detroit News, Seelinger’s contract included an upward mobility clause, meaning another organization could acquire him and potentially place him on its 40-man roster, giving him a clearer path to the majors.
Seelinger’s professional baseball journey has been anything but straightforward. Originally selected by the Pittsburgh Pirates in the 2017 MLB Draft, the New York native has spent years working his way through multiple organizations in pursuit of his first Major League opportunity. A native of Westbury, New York, Seelinger stayed close to home during his amateur career, pitching at Farmingdale State College before beginning his professional career.
His time with the Pirates was brief, as Pittsburgh traded him to the New York Yankees in 2018 as part of the deal that brought veteran infielder Adeiny HechavarrÃa to the Pirates. The following year, Seelinger was traded again, this time to the San Francisco Giants. He remained in their system until being designated for assignment and eventually waived in 2021.
Following stints in the Philadelphia Phillies organization, Seelinger took an unconventional route to keep his baseball career alive. He signed with the Long Island Ducks of the independent Atlantic League and dominated the competition, recording a remarkable 0.87 ERA over 21 appearances. His outstanding performance earned him another affiliated opportunity when the Tigers signed him, and he rewarded that decision with another strong campaign in 2025, posting a 2.74 ERA in 47 appearances split between Double-A and Triple-A.
Now, Seelinger returns to his home state with perhaps his best opportunity yet to finally reach the Major Leagues. His experience, consistency, and ability to generate quality innings out of the bullpen make him an intriguing addition for a Mets team searching for answers on the mound.
New York enters Monday with a disappointing 37-53 record and sits 11½ games behind the final National League Wild Card spot. Injuries and inconsistent pitching have once again undermined the club’s season, leaving the Mets looking for any spark they can find. With the team evaluating talent for both the present and the future, Seelinger could soon receive the long-awaited call to make his Major League debut after nearly a decade of perseverance through professional baseball.
