After the leap and slap, Yan stood straight up with his feet together and lifted both arms over his head. “Once I had him with two strikes I said, you know what, I’m going to throw that slider,” he said. That was already a signature celebration for Yan, who did the same after striking out a batter in a Mets spring training game earlier this year. Cleveland fans booed as Yan went to the dugout with the Mets ahead 4-3. And yeah, I’m going to enjoy my game any way that I want to.”
