Libuse is the start of a chain of players who lost their next match after beating the final person they beat. Confusing? Look:
Libuse Prusova LOST to Anne Kremer
who then LOST to Evie Dominikovic
who then LOST to Denisa Chladkova
who then LOST to Virginia Ruano Pascual
who then LOST to Justine Henin-Hardenne
who then LOST to Venus Williams
who then LOST to Serena Williams!
Of course there may be worse players in the draw...but Libuse holds the distinction of being the Ultimate Loser!
If Venus had won the final, Martina Muller would have been the Ultimate Loser.
And on the men's side, it was Hicham Arazi
