An injury-hampered world women's tennis number one Serena Williams suffered a shock defeat to Klara Zakopalova of the Czech Republic in the first round of the Andalucia Tennis Championships in Spain.
The top seed had clearly not recovered from a thigh problem that affected her performance in Miami last week and was broken seven times by Zakopalova, ranked 95 in the world... who won in 3 sets.
Williams lost to Belarussian teenager Victoria Azarenka in the final of the Sony Ericsson Open at the weekend and says she's sad to have failed in her opening match on the clay in Marbella in southern Spain.
World number four and second seed Jelena Jankovic thrashed Italy's Francesca Schiavone 6-2 6-1 in their first-round clash in Marbella.
