Jankovic ousted in first round

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

Two other seeded players had better luck in the Mexican 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 rallied to beat Julia Goerges of Germany 6-3, 3-6, 6-3.

Jankovic is No. 9 in the WTA rankings and the Latvian is 72nd.

Slovenia's Polona Hercog, who lost the Mexican Open final to Venus Williams on clay at Acapulco on Saturday, reached the second round with a 6-2, 6-4 win over Corinna Dentoni of Italy.

The Monterrey Open - unlike other Latin American tournaments in 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.
