There's a prank in baseball where the guys in the dugout ignore someone who just hit a home run. Usually when it's the first of his career, or the first time playing for that team. Anyway, it happened to first baseman Chris Davis of the Orioles on Wednesday.
But his reaction was even better. As he walked into the dugout, he MIMED his celebration by high-fiving nonexistent players, hugging the air, and pretending to slap guys' butts. (Search for "Davis' Solo Shot - 06-04-14." He does it at :49.)
