YIKES.
I don't even want to be standing on the other side of the net against someone like (the NUMBER ONE RANKED) Rafael Nadal - and the poor ball girl NEVER saw it coming.
According to TMZ, "Rafa was in the middle of his 2nd round match with Federico Delbonis on Thursday, when he ripped a vicious return shot that ended up missing his target and going wide."
Watching the video, our jaws are aching seeing it happen, in real time, at real speed, but the girl who looks to be no more than 15 years old shook if off, because honestly, she's on the court at the Australian Open, so you can't really break down without it being a deal, but Rafael felt SO bad as soon as it happened - he ran over to check on her and gave her a sweet kiss on the cheek - and after he won in the 3rd round, admitted he was still shaken up about it and gave the girl his headband.
