ANTWERP, Belgium (AP) -- Venus Williams opened her quest to claim a $1.3 million gold-and-diamond trophy with a 6-3, 6-0 win over Virginie Razzano of France on Wednesday, reaching the Diamond Games quarterfinals.
The third-seeded Williams would earn the trophy by becoming the first player to win the tournament three times in a five-year span. She was the champion in 2002 and 2003, then missed last year with a knee injury.
``I'm feeling good and feeling healthy,'' Williams said. ``It is my second tournament of the year and I'm on a good rhythm here.''
Williams lost in the fourth round of the Australian Open last month.
In other action Wednesday, seventh-seeded Patty Schnyder of Switzerland beat qualifier Camille Pin of France 6-3, 4-6, 6-1. Former No. 1 Kim Clijsters played fifth-seeded Nadia Petrova later Wednesday to set up a quarterfinal clash with Williams.
Top-seeded Amelie Mauresmo will play her opener Thursday.
COSTA DO SAUIPE, Brazil (Ticker) - The humid conditions took a toll Tuesday at the Brazil Open claycourt tennis tournament.
Second seed Fernando Gonzalez of Chile was upset and two seeds - No. 4 Filippo Volandri of Italy and No. 5 David Ferrer of Spain - were forced to retire midway through their matches.
Gonzalez, who won his first career hardcourt title last month in Auckland and reached the final two weeks ago in Vina Del Mar, was ousted by Austrian qualifier Peter Luczak, 3-6, 6-3, 7-5.
"Today was my biggest career win," Luczak said. "I didn't have anything to lose and I played well. Fernando Gonzalez is a tough opponent, especially here in South America, because he always has the crowd cheering for him. I think today I was luckier than when I played against him in Vina del Mar two weeks ago."
The tournament already had lost top seed Gaston Gaudio of Argentina, who withdrew Monday due to a strained groin after winning his second title in as many weeks in Buenos Aires on Sunday.
Volandri was leading Spain's Alberto Martin, 7-5, 1-0, when he was forced to retire due to the flu.
After winning the second set, 7-5, against fellow Spaniard Alex Corretja, Ferrer was unable to continue because of leg cramps in both legs. He appeared to have the momentum on his side as he recovered after getting blanked in the first set by the qualifier.
The highest remaining seed is No. 3 Juan Ignacio Chela of Argentina, who won the final 11 games in Monday's 6-4, 6-0 win over Germany's Lars Burgsmuller.
No. 7 Mariano Zabaleta defeated Mariano Puerta, 6-4, 6-2, in a battle of Argentines and No. 9 Ricardo Mello of Brazil, who replaced Gaudio in the main draw, rallied to past Spain's Albert Montanes, 3-6, 6-4, 6-4.
"It's very humid and warm, which makes it a little more difficult," Zabaleta said. "But we are used to 9playing) in these conditions, so it is not a problem."
In a night match, No. 6 Rafael Nadal of Spain bested Argentina's Jose Acasuso, 7-6 (7-1), 6-3.
Other first-round winners Tuesday were Argentine qualifiers Edgardo Massa and Martin Vassallo Arguello, Brazilian wild card Andre Sa and lucky loser Guillermo Garcia-Lopez of Spain.
