Jankovic ousted in Monterrey opener

Top-seeded Jelena Jankovic was upset in the first round of the Monterrey Open on Tuesday, losing 5-7, 6-4, 6-4 to Latvia's Anastasija Sevastova.

Jankovic is ninth in the WTA rankings, while Sevastova is No. 72.

Two other seeded players fared better in the hard-court event.

Third-seeded Anastasia Pavlyuchenkova of Russia defeated Anna Tatishvli of Georgia 6-1, 6-2; No. 4 Dominika Cibulkova of Slovakia downed Italy's Roberta Vinci 6-4, 6-3; and No. 5 Agnes Szavay of Hungary beat Julia Goerges of Germany 6-3, 3-6, 6-3.

Slovenia's Polona Hercog, who lost the final on clay Saturday against Venus Williams in Acapulco, reached the second round by beating Corinna Dentoni of Italy 6-2, 6-4.

The Monterrey Open -- unlike tournaments in Latin America during the last month -- is being played on hard courts rather than the clay favored by most Latin Americans and Spaniards. The 32-player field has only two players from Spain and none from Latin America.
