New York Mets reliever Jefry Yan made a memorable Major League Baseball debut on Wednesday night, August 6, 2026, at Progressive Field in Cleveland, Ohio. Called up earlier that week, the 29-year-old Dominican pitcher entered the game in the sixth inning and struck out the first batter he faced, Angel Martínez of the Cleveland Guardians.

Yan marked the occasion with a signature celebration where he "jump[ed] in the air and then smack[ed] the ground," a move that instantly set the baseball world on fire. This bold display was notable because, as reported, "nobody in their right mind would ever do that in public, much less in an actual Major League Baseball game."

The celebration drew immediate reactions, including from Guardians player Jose Ramirez, who mocked Yan after Cleveland took the lead. Yan's charged mound demeanor reflected his intensity and frustration, making his debut one of the most talked-about moments in recent MLB history.

Whatever fans might have envisioned about a debut celebration, it "won't come close to what actually transpired on the field," underscoring the uniqueness of Yan's performance and celebration.
