Roddick just being an idiot again. He signalled challenge simultaneously with the out call, so he was never going to play the ball if the call hadn't come. Good umpiring
He didn't signal challenge. He put his fist in the air after the out call because he had won the match.
Got to love the Roddick rant at the end of the match. Point should have been replayed no doubt. Andy always gets the short end of the stick on that rule.
What did he serve like 80% first serves? RIDICULOUS!
