Mets Rookie Jefry Yan Has Viral High-Flying Celebration After Striking Out His 1st MLB Batter
Yan struck out 77 batters in 41 2/3 innings this season and joins a bullpen thinned by 11 Mets trades since June.
On Wednesday, Aug. 5, 2026, New York Mets rookie Jefry Yan made his major league debut in Cleveland, striking out pinch-hitter Angel Martinez with an 88.7 mph slider during the team's 6-5 win over the Cleveland Guardians.
Following the Mets' trade deadline fire sale, the 29-year-old left-hander joined a patchwork crew as the club dealt 11 players since June to replenish a farm system that had taken a deep dive in rankings.
Working construction while playing independent baseball for five years, Yan finally reached the majors after stepping away from professional baseball; he escaped a bases-loaded jam without giving up a run in his debut appearance.
Manager Andy Green described the preceding Monday as a 'tough day' of phone conversations with traded players, yet emphasized that roster turnover provides a 'real opportunity' for new players to contribute and prove themselves.
Data from Baseball America shows only 6.3% of minor leaguers acquired at the deadline produce major league value, yet the Mets can build around promising prospects like Jefferson Rojas and Sammy Stafura acquired this year.
