Australian Open 2013: Federer, Azarenka and Williams all in action Coverage: BBC Sport website (daily live text commentaries); 5 live sports extra (commentaries) & TV/online streaming (both finals) Four-time winner Roger Federer, top women's seed Victoria Azarenka and five-time champion Serena Williams are all in action during the second day's play at Melbourne Park, while Britain's Andy Murray booked his place in round two . Murray analysis That was as solid an opening win as you could wish for at a Grand Slam tournament, Murray looking a class apart and more physically imposing than ever. A few wayward drop shots and slip-ups on serve will give coach Lendl something to glower about in the post-match debrief, but Joao Sousa will have to come up with something pretty extraordinary if he is to trouble the Briton in round two. Andy Murray (GB) [3] beat Robin Haase (Ned) 6-3 6-1 6-3 The British number one started his quest for back-to-back Grand Slam titles with a commanding victory over the Dutchman. Victoria Azarenka (Blr) [1] beat Monica Niculescu (Rom) 6-1 6-4 World number one Azarenka kicked off her Australian Open title defence with a hard-fought win. The Belarusian top seed, who beat Maria Sharapova in the final last year, won the first set easily but had to save two break points to stop herself going 4-0 down in the second. Azarenka, who pulled out of a warm-up event in Brisbane because of an infected toe, said: "It's much better. I have been practising for the last couple of days so I am really happy it's all gone and it's behind me. It's great to be back, there were a lot of overwhelming emotions out there. I started really well but the second set was a struggle. I am pleased to get through. Benoit Paire (Fra) v Roger Federer (Swi) [2] Bernard Tomic (Aus) v Leonardo Mayer (Arg) Yanina Wickmayer (Bel) [20] v Jarmila Gajdosova (Aus) Caroline Wozniacki (Den) [10] beat Sabine Lisicki (Ger) 2-6 6-3 6-3 The former world number one looked in trouble after losing the first set and falling 3-0 down in the decider, but she fought back superbly to win the next six games and reach the second round. The 10th-seeded Dane only hit 12 winners to 45 for Lisicki, but the big-hitting German also made 57 unforced errors to just eight for Wozniacki. Serena Williams (USA) [3] beat Edina Gallovits-Hall (Rom) 6-0 6-0 Williams, the reigning Wimbledon and US Open champion, recovered from a painful ankle injury to power her way into the second round. The world number three, leading 4-0 in the first set, slipped on the surface and lay motionless before receiving lengthy medical attention. Williams had her ankle re-strapped and carried on gingerly, but was otherwise untroubled as she secured an emphatic victory. "Oh, I'll be out there," she said when asked if she would be playing her next match on Thursday against either Slovak Magdalena Rybarikova or Garbine Muguruza of Spain. Unless something fatal happens to me, there's no way I'm not going to be competing. I'm alive. My heart's beating. I'll be fine. I've been injured before. I've played this tournament with so many injuries and was able to come off pretty on top. So for me it's just another page and a great story to tell the grandkids one day. Jo-Wilfried Tsonga (Fra) [7] v Michael Llodra (Fra) Juan Martin Del Potro (Arg) [6] v Adrian Mannarino (Fra) Carla Suarez Navarro (Spa) beat Sara Errani (Ita) [7] 6-4 6-4 Petra Kvitova (Cze) [8] beat Francesca Schiavone (Ita) 6-4 2-6 6-2 Sloane Stephens (USA) [29] v Simona Halep (Rom) Marinko Matosevic (Aus) v Marin Cilic (Cro) [12] Gael Monfils (Fra) v Alexandr Dolgopolov (Ukr) [18] Melanie Oudin (USA) v Laura Robson (GB) - Court Three Jamie Baker (GB) v Lukas Rosol (Cze) - Court 20 Stat of the day Japanese veteran Kimiko Date-Krumm , aged 42, became the oldest woman to win a main draw match at the Australian Open when she beat 12th seed Nadia Pedrova 6-2 6-0. She surpassed Britain's Virginia Wade, who won a match in 1985 at the age of 40 years 138 days, as the oldest winner. Date-Krumm, who made her first appearance in Melbourne in 1990, still has some way to go to become the oldest winner at a Grand Slam. The record is held by Martina Navratilova, who was 47 when she won a match at Wimbledon in 2004.
