Top seeds through

It was a hot day for the top seeds on a cold, windy Sunday at the Pacific Life Open.

The men's leading trio of Roger Federer, Rafael Nadal and Andy Roddick all won their opening matches, while women's number one seed Justine Henin-Hardenne, number two Lindsay Davenport and number three Maria Sharapova also scored victories.

Federer fought off Chile's Nicolas Massu 6-3 7-6 in the second round, while Nadal posted a 6-4 6-4 win over Czech Jan Hernych.

Third seed Roddick battled past Argentine Jose Acasuso 7-6 6-0.

"I know he's a tough competitor and I'm happy to be through," said twice defending champion Federer.

The 19-year-old Nadal, who beat Federer to win the title in Dubai in his last tournament, struggled with the wind but was too consistent for his opponent on the day.

"It is very difficult to play like this," the Spaniard said. "It didn't feel very good. But I won."

Andre Agassi lost control of his temper in the second set but then won the final six games in a 6-4 4-6 6-2 victory over Paul Goldstein.

Britain's great teenage hope fell, however, Andy Murray losing 6-1 3-6 6-3 to fifth seed Nikolay Davydenko of Russia.

After winning the title in San Jose last month with back-to-back wins over Andy Roddick and Lleyton Hewitt, the 18-year-old Murray lost in the quarter-finals of Memphis, the first round of Las Vegas and now in the second round of Indian Wells.

In women's action, Henin-Hardenne advanced, making quick work of Tszvetana Pironkova 6-2 6-2, while Sharapova registered a 6-4 6-0 win over Lisa Raymond.

Former world number one Martina Hingis beat Austria's Sybille Bammer 6-0 6-3.
