I don't know if it's the worst tennis match ever, but it's probably the worst I've ever seen.
Svetlana Kuznetsova held on long enough to not lose against Anna Chakvetadze, taking the third set 6-1. There were dunks into the net, sailing errors and swings and misses at floating volleys. There were 13 breaks of serve, and 81 (!) unforced errors (versus 31 winners).
Needless to say, this has confirmed what skeptics thought about the bottom half of the women's draw. That is to say, don’t bet on Kuznetsova against the winner of the Venus Williams-Justine Henin semifinal.
