Federer, SWilliams Advance at Hot Australian Open With the sun setting at the end of a hot day at the Australian Open, Roger Federer ensured he made the most of a favorable evening draw. Wearing bright pink shoelaces, Federer advanced to the third round with a 6-3, 6-4, 6-4 win over Russian Nikolay Davydenko on Thursday. The 17-time Grand Slam champion was a winner of sorts before he even stepped out at Rod Laver Arena, having received the luck of the draw - a 7 p.m. start time after the worst of the 106-degree heat had subsided. "I'm very happy to have played so well against him," Federer said of his 18th win over Davydenko in their 20 matches. Other championship contenders in the men's and women's draws, including Andy Murray, Serena Williams and defending champion Victoria Azarenka, had to withstand the high temperatures that aren't unusual for this time of year in Melbourne. A dancing Azarenka and an ankle-wrapped Williams had easy straight-set victories. U.S. Open champion Murray also won routinely, beating Joao Sousa of Portugal 6-2, 6-2, 6-4 on Hisense Arena, the second show court at Melbourne Park. "You need to be the one that's trying to dictate the points in these conditions," said Murray, who practices in Florida. Miami is the perfect preparation. It's hot and humid there, although it certainly doesn't get up to (99 degrees). It was a good match to get done in straight sets.  Switzerland's Roger Federer makes a backhand return to Russia's Nikolay Davydenko during their second round match at the Australian Open tennis championship in Melbourne, Australia, Thursday, Jan. 17, 2013. Williams went into Thursday's match with an injured right ankle from Tuesday's match. She didn't seem troubled by the ankle, but did finish with a swollen lip after hitting herself with her racket. "It's OK," she said. It's a war wound. I think it happens to everyone, but I have never busted it wide open like that. I was like, 'Oh, no. I can't have a tooth fall out.' That would be horrible. Williams lifted her tempo on the biggest points, including when she finally won an 18-minute game to open the second set en route to a 6-2, 6-0 win over Garbine Muguruza. Usually I feel injuries after the match but, so far, so good. I felt pretty much better than I ever dreamed of expecting to feel," Williams said of her ankle. She later combined with sister Venus to win in the first round of doubles, showing no signs of trouble with the ankle. Despite the high temperatures, tournament officials left the retractable roofs on both main arenas open because a combination of factors including humidity and court temperature didn't warrant making the venues a temporary indoor haven from the heat. Ice vests and towels helped players keep their cool, and a women's tour rule allowing a 10-minute break between sets was invoked late in the day, tournament director Craig Tiley said. "It's always the referee's discretion, but the lack of humidity helped us today," Tiley said. Australia sweltered through a week of record high average temperatures this month, but the first three days of the Open were relatively mild. The top-ranked Azarenka pranced into Rod Laver Arena for the first match of the day, and said she's starting to find some rhythm after beating Eleni Daniilidou 6-1, 6-0 in 55 minutes. "I felt like I'm back into the competitive mode," Azarenka said. 94-ranked Daniilidou only won 10 points in the first set and was shut out in the second despite having triple break point in the fourth game. Azarenka had her friend and musician RedFoo in the stands watching and signing autographs, and said she went onto the court listening to a "great mix of disco music and a little bit of new music."
