MOSCOW: Kazakh qualifier Zarina Diyas beat top-seeded Jelena Jankovic 6-1, 6-2 Thursday in the second round of the Kremlin Cup. The 268th-ranked Diyas, who celebrated her 17th birthday Monday, led 5-0 in the first set when Jankovic, 2008 champion here, called for a doctor and had her blood pressure checked. Jankovic, who has qualified for next week's WTA championships, managed to break back early in the second set but Diyas then broke the Serb two times. “I had nothing to lose,” Diyas said. “I just relaxed and played my best tennis.” Diyas, whose parents moved from Kazakhstan to Prague, Czech Republic, 12 years ago, said that watching Martina Hingis' matches on TV had inspired her to play tennis. She will face sixth-seeded Maria Kirilenko of Russia, who routed Kateryna Bondarenko of Ukraine 6-0, 6-0. Vera Dushevina advanced to the quarterfinals with 6-4, 6-2 win over her fellow Russian Elena Vesnina. In the men's second round, Viktor Troicki of Serbia rallied to upset third-seeded Jo-Wilfried Tsonga of France 3-6, 6-3, 7-5. Earlier, Horacio Zebalos of Argentina beat Romanian qualifier Victor Crivoi 7-5, 7-6 (1), while Alexandr Dolgopolov upset his fellow Ukrainian, seventh-seeded Sergiy Stakhovsky, 6-2, 7-6 (4). Russia's Igor Kunitsyn upset sixth-seeded Andrey Golubev of Kazakhstan 6-4, 7-5. Serving at 6-5 down, the 34th-ranked Golubev saved two match points but sent a shot wide on a third. Denis Istomin of Uzbekistan rallied to beat former champion Paul-Henri Mathieu of France 1-6, 7-5, 6-3. Federer ousts Dent Roger Federer cruised into the Stockholm Open quarterfinals Thursday in his 900th match on the ATP Tour, beating Taylor Dent of the United States 6-1, 6-2 in 51 minutes. Federer outclassed Dent to record his 727th tour win, in his first match in the Swedish capital for a decade. It took the 16-time Grand Slam winner just 17 minutes to win the first set, breaking Dent twice. Dent put up more of a fight in the second, having two break points in the fourth game, but Federer upped the tempo. Federer will face countryman Stanislas Wawrinka in the next round. Second-seeded Robin Soderling also advanced by defeating Germany's Benjamin Becker 6-3, 6-3. The fifth-ranked Swede broke Becker in the sixth game to take the first set and twice in the second to the delight of the Swedish public. Fourth-seeded Ivan Ljubicic of Croatia breezed past Arnaud Clement of France 6-3, 6-4. Ljubicic had 12 aces on the way to his 10th straight victory over Clement. Ljubicic will face countryman Ivan Dodig next, after he routed Germany's Tobias Kamke 6-1, 6-1, in only 53 minutes.
