Overview
- The Mets acquired Seelinger from the Detroit Tigers for cash and added him to the major‑league roster before Tuesday’s home game at Citi Field to satisfy the clause in his contract.
- Seelinger made his MLB debut Tuesday and allowed seven earned runs in the seventh inning, took the loss in a 16-12 game, and then threw a scoreless eighth inning.
- The upward‑mobility clause required the acquiring club to place Seelinger on the big‑league roster within 72 hours or make him available to other teams, which accelerated the Mets’ decision to activate him.
- New York designated Seelinger for assignment on Wednesday after the 52‑pitch debut as the club needed fresh bullpen arms and moved to address roster spots.
- Seelinger is a 31‑year‑old Westbury native who spent nearly a decade in the minors, posted a 3.89 ERA with 49 strikeouts in 39 1/3 Triple‑A innings this year, and his quick rise highlights the Mets’ short‑term bullpen strain ahead of the trade deadline.
