The Mets selected Yan's contract and then optioned him to Triple-A Syracuse on Thursday.
Yan likely had an opt-out clause in his minor-league contract, and the Mets will add him to the 40-man roster to prevent him from leaving. The lefty reliever has struck out a whopping 63 batters over 33.1 innings between Double-A Binghamton and Syracuse in 2026, though he's also issued 24 walks. Yan has never pitched in the majors.
