yay!i'm so happyandy won, but david has a point. a close call favors the americans. like the justine vs jennifer match. there were so many calls that were justine's that was called out when it was proven to be in by the replays.
Don't blame the umpire. Someone has once posted the rules for incidents like this, and play has to continue.
David should have played on. And yes, he should never have made that error when leading 4-2 in that TB.
