MONTERREY, México - A day after the No.1 seed was bundled out of the tournament things started to look difficult for the No.2 seed, but Daniela Hantuchova was able to hold on, fending off a late surge from Lourdes Domínguez Lino and moving into the second round in straight sets.

Hantuchova, the No.2 seed, was leading 63 51 when Domínguez Lino kicked into high gear, winning five games in a row - even saving a match point down 63 53 - and pushing the second set to a tie-break. She saved another match point late in the breaker before finally falling in an hour and 43 minutes, 63 76(6).

"The conditions here are not easy because of the altitude so it takes some time to get used to. That's why I'm glad we came early to prepare!" Hantuchova said after the match. "I'm very happy to be through to the next round."

Jelena Jankovic was seeded No.1 here but lost her opener to Anastasija Sevastova Tuesday. Hantuchova's was the only first round left to be played.

In second round action, No.3 seed Anastasia Pavlyuchenkova was able to move on, beating out last week's Acapulco finalist, Polona Hercog, at night, 62 63. No.7 seed Aleksandra Wozniak wasn't so lucky, losing to Alizé Cornet, 62 63. Vania King and Klara Zakopalova also reached the quarterfinals.

"I am very happy," Cornet said of her upset over Wozniak. "Aleksandra had won the last two times so I was eager to win today."

The remaining four second round matches will be played on Thursday.
