Indian Wells:The fourth round of the men's draw at the Pacific Life Open in Indian Wells continued on Wednesday. Number four seed Nikolay Davydenko had his sights set on a quarterfinals place, but the Russian faced a tough test in the shape of Andrew Murray of Scotland. Murray, the number 13 seed, squandered a golden opportunity to wrap up the first set in the tenth game before bravely fighting back from a break down to force a tiebreaker. Davydenko would soon find himself a set down as Murray dominated matters, putting his powerful serve to good use and taking it 7-3. He may have been knocked out of last year's Pacific Life Open by Davydenko, but Murray continued his rapid rise up the tennis hierarchy with a 7-6(3), 6-4 victory that was helped in no small part by 10 aces. Murray has now won 18 of the 21 matches that he has played in 2007, including a successful defence of his title in San Jose. Second victory It was Murray's second victory over Davydenko this year, following a straight sets win in Doha, and the 19-year-old was pleased with his day's work. "Yes, it was a good match. Served well in the important moments. Played tough at the end. Didn't start too well, but managed to hang in at the end of the first set when I had the four set points at 5-4, and then I got broken to go 6-5 down and came back well. So, I was happy to come through," he said. Another 19-year-old rising star, Novak Djokovic, looked to follow Murray into the quarterfinals when he took on Julien Benneteau. The Serbian number 12 seed had been beaten by Benneteau in the first round of last year's Pacific Life Open, but Djokovic gained his revenge with a resounding victory. Djokovic impressed in the first set, which he took 6-3, but his second set performance was almost faultless. France's Benneteau took just one game as Djokovic progressed to a last eight meeting with Spain's David Ferrer after wrapping up the match 6-3, 6-1. Li wins The first women's quarterfinal saw Vera Zvonareva face China's Li Na. Russia's Zvonareva had knocked out top seed Maria Sharapova on Tuesday and had an opportunity to take the upper hand in the first set of Wednesday's match when she reached deuce on the Li serve at 4-4. However, number 12 seed Li held her nerve and her serve before breaking Zvonareva in the next game to take the first set 6-4. Li had the edge over her number 15 seed opponent, keeping Zvonareva on the run with a succession of measured groundstrokes. But she would have to twice survive from set point down in the tenth game of the second set before going on to claim a 6-4, 7-5 victory. Li advanced to the semi-finals of a tier one event for the second time in her career and she will face either Slovakian Daniela Hantuchova or Shahar Peel of Israel in the last four.
