The pair outserved their Spanish opponents winning 56 percent of points on their first serve compared to the Spaniards 47 percent.

Chan and Chuang, the No. 5 seeds and runners up in the doubles at the Australian Open earlier this year, beat Czech Iveta Benesova and Russian Galina Voskoboeva 6-1, 6-2 on Thursday.

Meanwhile, Taiwan's Hsieh Su-wei (
However they were out of luck yesterday against Spain's Nuria Llagostera Vives and Maria Jose Martinez Sanchez, going down in straight sets 6-7, 3-6.
In the women's singles Jelena Jankovic overpowered Venus Williams 6-4, 4-6, 6-1 in a high-quality third round tie yesterday.
The 22-year Serb has been in impressive form this year and had beaten Williams on the last two occasions they had met.
Jankovic won the toss, chose to receive and the tactic paid off as the 25-year-old Williams served up a dreadful game.
Jankovic moved 2-0 before Williams started to find her range and the fourth-seed from Belgrade comfortably held on to her serve a further four times to take the set 6-4 in 30 minutes.
Williams came into the third round tie as a five-times Grand Slam title winner but she has never been too comfortable on clay despite reaching the Paris final in 2002 when she lost to sister Serena.
This time the American held her serve to open the second set and then attacking the Jankovic forehand paid dividends as she broke in the next game to take a 2-0 lead.
Williams had a chance to go 3-0, but Jankovic held firm and had her opponent gasping for breath after a punishing series of long rallies.
That paid dividends in the fifth game as the Serb broke back to get to 2-3, but Williams hit back immediately winning the next three games to move 5-2 up.
She failed to level the tie on her own serve but did so in the following game breaking Jankovic's serve for the third time in four attempts.
But it was the Serb who proved the stronger in a pulsating final set breaking the Williams serve in the third and fifth games to move 4-1 up.
That broke Williams's resistance and two games later it was all over.
"I stayed mentally very strong in third set and I really went for my shots," Jankovic said. "I was a little bit tired in the second set, but I just went for it in the third and it paid off."
In the men's second round tie held over from Thursday Russia's Igor Andreev defeated Olympic champion Nicolas Massu of Chile 6-3, 3-6, 6-3, 7-5.
