Defending champion Nikolay Davydenko crashed out of the Malaysian Open in the second round Wednesday, beaten by fellow Russian Igor Andreev. Andreev won 7-6 (7-5), 5-7, 6-3 in 2 hours, 47 minutes in stifling heat for his first victory over Davydenko in seven years. Davydenko, who got a bye in the first round, looked to be on course for a relatively straightforward victory when he led 5-1 in the first-set tiebreak, but Andreev found his range with his forehand and rattled off six points in a row to steal it. Davydenko started the second set on fire, racing to a 5-1 lead, and although Andreev fought back to level it 5-5, Davydenko took the next two games to make it one set apiece. Andreev's more aggressive approach in the decider paid dividends as Davydenko began to wilt in the heat. Andreev will face fellow qualifier Milos Raonic Friday after the Canadian beat seventh-seeded Sergiy Stakhovsky 6-7 (8), 7-6 (9), 6-3 to reach his first ATP quarterfinal. Meanwhile, fourth seed Mikhail Youzhny was made to work hard for his 6-1, 5-7, 7-5 victory over Ukraine's Alexandr Dolgopolov. Melzer, Gulbis win Third seed Jurgen Melzer kick-started his week in Asia at the Thailand Open Wednesday, powering past Israeli Dudi Sela 6-3, 6-4. The Roland Garros semifinalist advanced to his tenth quarterfinal of this season after an opening bye at Bangkok's Impact Arena. It was Melzer's third victory over Sela this year. He will now wait for Friday's match with either 2009 finalist Viktor Troicki of Serbia or Finn Jarkko Nieminen. Fourth-seeded Latvian Ernests Gulbis fought for almost three hours to get past German veteran Rainer Schuettler 7-6 (7-4), 6-7, (4-7), 6-4. Spain's Guillermo Garcia-Lopez needed three hours to defeat Frenchman Florent Serra 7-5, 6-7 (3-7), 7-5, with the winner firing 17 aces. Schiavone advances French Open champion Francesca Schiavone beat local favorite Kimiko Date Krumm 6-3, 6-3 to reach the Pan Pacific Open quarterfinals Wednesday, while top-seeded Caroline Wozniacki cruised in. Wozniacki overpowered Anastasia Pavlyuchenkova of Russia 6-1, 6-2. Wozniacki downed Pavlyuchenkova for the fifth straight time - and third time this year - and will meet No. 6 seed Agnieszka Radwanska of Poland in the quarterfinals. Radwanska beat Germany's Andrea Petkovic 6-3, 6-3.
