Top seed Francesca Schiavone was a first-round upset victim Tuesday at the $220,000 Barcelona Ladies Open.

Belarusian Olga Govortsova drove out the 2010 French Open champion and 2011 Roland Garros runner-up Schiavone in 6-4, 6-3 fashion on the red clay at Centre Municipal de Tenis Vall d'Hebron.

Schiavone titled here in 2010 by beating reigning Barcelona champion Roberta Vinci in an all-Italian finale.

Three other seeds avoided upsets, as No. 2 German Julia Goerges grounded France's Aravane Rezai 6-4, 6-0, No. 3 Slovakian Dominika Cibulkova drubbed Frenchwoman Iryna Bremond 6-0, 6-3, and No. 5 Italian Flavia Pennetta handled Spain's Lara Arruabarrena-Vecino, 6-0, 6-4.

A trio of unseeded Spaniards -- Carla Suarez Navarro, Estrella Cabeza Candela and Laura Pous-Tio -- also reached the second round in Barcelona, as did Czech Klara Zakopalova and Ukrainian qualifier Yulia Beygelzimer.

This week's winner will claim $37,000.
