Jefry Yan made his MLB debut Wednesday with the Mets, and he marked the occasion with a memorable celebration of his first career strikeout. According to ESPN, Yan jumped high in the air with his feet spread apart, landed on the front of the mound and then slapped the grass with his left hand while briefly going to a knee. Sportsnet reported the strikeout came against Cleveland Guardians batter Angel Martínez.
Yahoo Sports noted that Yan's celebratory routine came after a long path to the majors—twelve years and a blown elbow, per the outlet. The 30-year-old pitcher's acrobatic response to his first strikeout quickly went viral across social media.
When Guardians fans booed him during the game, per reporting from r/baseball, Yan responded philosophically about the crowd reaction. "They can do whatever they want. They're paying for tickets so if they want to yell at me or if they want to boo me, they can do whatever they want. I'm in my zone," he said.
