MELBOURNE — Serena Williams survived a busted lip and Roger Federer and Andy Murray raced into round three on a day of ice-packs and sunscreen as temperatures soared at the Australian Open Thursday. Defending champion Victoria Azarenka toyed with the fourth “double bagel” of the women's draw as she went through 6-1, 6-0. The top seed thumped Eleni Daniilidou to remain on course for a semifinal with the thundering Serena, who appeared unimpeded after rolling her ankle in round one as she demolished Spanish teen Garbine Muguruza 6-2, 6-0. But Serena did not escape unhurt as she smashed herself in the mouth with her racket during the first set, leaving her bleeding and fearing she had lost a tooth. Braving the heat, US Open champion Murray maintained his Grand Slam winning streak with a quickfire 6-2, 6-2, 6-4 destruction of Portugal's Joao Sousa — and then headed straight for the Melbourne Park ice baths. Former world No. 1 Caroline Wozniacki also progressed, beating Croat Donna Vekic 6-1, 6-4, but eighth seed Petra Kvitova, the 2011 Wimbledon champion, crashed out to Britain's Laura Robson, 2-6, 6-3, 11-9. Meanwhile, Japan's Kimiko Date-Krumm, 42, became the oldest player to make a Grand Slam third round since Renee Richards in 1979. Former finalist Jo-Wilfried Tsonga booked his place in the next round with a straight-set win over Japan's Go Soeda, and Lithuanian qualifier Ricardas Berankis stunned German 25th seed Florian Mayer. Big-serving Canadian Milos Raonic downed the Czech Republic's Lukas Rosol, and Germany's 17th seed Philipp Kohlschreiber had a straightforward win against Amir Weintraub of Israel. France's Gael Monfils inexplicably double-faulted four times on match points before finally clinching an erratic, five-set win against Lu Yen-hsun, and sixth seed Juan Martin Del Potro beat Germany's Benjamin Becker. In the showpiece evening match, Federer blew Nikolay Davydenko away 6-3, 6-4, 6-4 to extend his record to 18-2 against the Russian, and set up an encounter with brash Australian Bernard Tomic, 20. Federer stretched his record over Davydenko to 18-2 with a dominant performance containing three service breaks from 13 break point opportunities. “It's nice he's been able to turn it around after a tough end of the year last year. It seems he's playing well,” Federer said of Tomic, who won his first tour title this month. As women's seeds Roberta Vinci, Maria Kirilenko and Yanina Wickmayer joined Azarenka and Williams in the next round, Australian media howled at the defeat of Samantha Stosur, who was bundled out by Zheng Jie Wednesday. Tsonga will face unseeded Slovenian Blaz Kavcic, who took almost five hours before overcoming Australian James Duckworth 10-8 in the fifth set. Tomic secured a 6-7 (4/7), 7-5, 7-6 (7/3), 7-6 (10/8) win in 2hr 55min to reach the third round and continue his unbeaten start to the year after claiming his first tour title at the Sydney International. France's Gilles Simon will be Monfils' next opponent after beating Canadian Jesse Levine in three sets, while compatriot Richard Gasquet accounted for Colombia's Alejandro Falla in straight sets. Croatia's 12th seed Marin Cilic beat American qualifier Rajeev Ram in straight sets, and Frenchman Jeremy Chardy knocked out Spanish 30th seed Marcel Granollers in four sets. Nadal set for Chile Open Rafael Nadal's return to tennis will be full on after revealing he's entered three of the four clay-court events in the ATP's Latin American swing next month. Chile Open organizers announced Thursday that Nadal will make his debut in Vina del Mar in the week starting Feb. 4. — Agencies
