TOKYO, Oct. 2 (UPI) -- Top seed Lewitt Hewitt avoided the upset bug Wednesday at the rain-delayed Japan Open as three other seeds from the top 10 fell out of the tournament.
Hewitt, who received a bye in the first round, cruised into the third round with a 6-2, 6-2 victory over unseeded American Michael Chang. The world's top-ranked player and reigning Wimbledon champion, Hewitt is seeking his fifth title of the year and already has qualified for the season-ending Tennis Masters Cup in November.
Chang has claimed 34 career titles but is struggling through his worst year as his career winds down. He is just 7-18 on the ATP circuit in 2002 with one Challenger tournament win in Calabasas.
Germany's Alexander Waske defeated Moya, 6-4, 7-5; Slovakia's Karol Kucera bounced Corretja, 3-6, 6-3, 7-6 (7-3); and Swedish qualifier Maguns Larsson dispatched Lapentti, 7-5, 6-2.
Argentina's Agustin Calleri, the 12th seed, toppled American Alex Kim, 6-4, 6-4, in the first round but fell to France's Jerome Golmard, 6-3, 6-2, in his second match of the day.
Also reaching the round of 16 was France's Anthony Dupuis, who survived a pair of tiebreakers to eliminate No. 13 seed Wayne Arthurs of Australia, 7-6 (7-5), 7-6 (8-6). Dupuis also was forced to win twice.
In other first-round matches, Denmark's Kenneth Carlsen downed Israel's Noam Okun, 6-4, 6-4; American Cecil Mamiit outlasted Brazil's Alexandre Simoni, 6-3, 3-6, 6-2; Spain's Feliciano Lopez dispatched Austria's Stefan Koubek, 6-4, 6-4; and German Michael Kohlmann downed American qualifier Doug Bohaboy, 6-1, 6-3.
On the women's side, No. 3 Arantxa Sanchez-Vicario of Spain was the top player to advance, posting a 6-0, 6-2 first-round win over Russian qualifier Maria Kirilenko.
No. 4 Emmanuelle Gagliardi of Spain outlasted Russian wild card Maria Sharapova, 2-6, 7-6 (7-4), 6-4, and sixth-seeded Russian Svetlana Kuznetsova of Russia dispatched France's Virginie Razzano, 7-5, 6-2.
Also, No. 7 Virginia Ruano Pascual of Spain advanced with a 6-0, 6-1 romp over Korean qualifier Jin-Hee Kim, and eighth seed Jelena Kostanic of Croatia toppled Japan's Saori Obata, 6-4, 7-6 (7-3).
Japan's Yuka Yoshida posted the first upset on the women's side, cruising past Zimbabwe's Cara Black, the fifth seed, 6-2, 6-1.
