The livescore board went from him leading 6-5 5-5 to him losing the match on a "default". Note that when Roddick retired due to injury it said "retired", not "default", so it clearly wasn't an injury. Unless the site screwed up.
Now the resutls page is calling it a "walkover".
So what on earth did he have to do to get defaulted?!
Okay really weird; apparantly he didn't agree with a line judge, was arguing with that person, then played on. He made footfaults (deliberately ) , got one penalty point, so he was furious and offended the line judge, it's not clear what he said, but he got a second penalty point and was defaulted...
I'm glad and really mad at the same time. I thought he was injured He is, but only mentally! Get it together Xavier!!! DAMN IT! For once in your career, you're playing good, with no injuries! Take advantage of it!!! GOD!!! You shouldn't freak out like that for stupidities!
