I've watched this video a couple times, and I can't help but think that Michael Llorda could have veered off into a slightly different direction and avoid plowing over the ball girl like this. I'm sure he didn't do it on purpose though, and if he thought he could have avoided her, he obviously would have. He ended up getting hurt and dropping out of the match afterwards, so it cost him dearly.
