Rafa Nadal reached the final of the Shanghai Masters when Feliciano Lopez retired Saturday, the second evening in a row when the top seeded Spaniard's opponent has withdrawn injured. World No. 2 Nadal was coasting at 6-1, 3-0 when his compatriot Lopez, who had a foot injury, became the ninth player to fail to finish a match at the $3.24 million tournament. The Australian Open champion will face Nikolay Davydenko in the final after the Russian sprang an upset on second seed Novak Djokovic with a 4-6, 6-4, 7-6 victory. Nadal, who benefited from Ivan Ljubicic's withdrawal from their quarterfinal to reach the last four, has not played a tour final since May's Madrid Masters. Sixth seed Davydenko lost twice to Djokovic at the Masters Cup here last season, the second in the final, but was an altogether different proposition this year. The 28-year-old kept Djokovic under pressure throughout the three-hour contest before running away with the deciding tiebreak, taking it 7-1. “The match today was long and heavy,” Davydenko told reporters. “This was really difficult all match. I was lucky, he was lucky. In the tiebreak, I was more lucky.” Serbian Djokovic, who will move back to world No. 3 next week and was chasing back-to-back titles after his win in Beijing last Sunday, left the court dejected after falling to his first defeat in his last 11 matches in China. Stosur-Schiavone final In Osaka, third-seeded Samantha Stosur of Australia upset defending champion Caroline Wozniacki 6-0, 4-6, 6-4 Saturday to advance to the final of the Japan Women's Open. Stosur, who had 12 aces, broke the top-seeded Dane to go up 5-4 in the final set and then held serve to defeat the US Open finalist in 1 hour, 45 minutes at Utsubo Tennis Center. Stosur will face fourth-seeded Francesca Schiavone of Italy in Sunday's final. Schiavone needed just 59 minutes for a 6-2, 6-1 win over India's Sania Mirza. Stosur had lost to Wozniacki in two previous meetings this year but improved to 2-2 against the sixth-ranked player. The Australian, despite being 15th in the world rankings, is still looking for her first WTA singles title, having lost all five of her previous finals. Schiavone broke Sania four times and never faced a break point to improve to 3-0 against the unseeded Indian. Like Stosur, Schiavone has an unenviable record in tournament finals, standing at 1-9. Wickmayer-Kvitova final In Austria, Yanina Wickmayer of Belgium and Petra Kvitova of the Czech Republic advanced to the final of the Generali Ladies Saturday after straight-set wins over the top two seeds. No. 3 Wickmayer beat top-seeded Flavia Pennetta of Italy 7-6 (5), 6-3, and Petra Kvitova of the Czech Republic upset second-seeded Agnieszka Radwanska of Poland 6-3, 6
