Did you see what happened there? Third baseman Dean Anna tripped over Brian McCann's mask after he tossed it away to follow the pop-up, then McCann flopped backwards over Anna. Both guys are fine, so feel free to laugh.
I'm pretty sure the last thing the Yankees wanted to see was their new $85 million catcher flop over the 39th or 40th man on the 40-man roster. If McCann had gotten hurt ... oh boy.
