This poor kid in a Buster Posey jersey took a Brandon Crawford ground rule double to the knee and went down hard:
It wasn't all bad, though. He eventually got the baseball he was gunning for (and an ice pack, too). He triumphantly raised the one of those that mattered above his head:
The nasty bruise he'll likely have on his knee will heal with time, and he'll have a souvenir for his troubles. And hey, he didn't even have to be injured by the man whose jersey he was wearing to get it. Worth it!
