All of the big names took care of business on Day 4 at the 2013 Australian Open. Roger Federer, Andy Murray, Victoria Azarenka and Serena Williams all advanced in straight sets, showing no signs of early-season rust in the process.
In fact, it was a pretty straightforward day around Melbourne Park. There were no shocking upsets as nearly all of the seeded players advanced, most with relative ease. The biggest upset was rising star Laura Robson eliminating No. 8 seed Petra Kvitova.
Two rounds are now complete at the season's first major. Let's take a look at some of the notable stories from Day 4, followed by a full list of the day's results.
Nikolay Davydenko was playing good tennis to start the season. He reached the finals in Doha, a run that was highlighted by a victory over David Ferrer. However, the veteran was no match for Federer, who breezed to a win in straight sets.
The Swiss superstar has captured the Aussie Open title four times and would love to make it five, which would silence his doubters. The No. 2 seed has definitely looked like a man on a mission in the first two rounds, advancing in his usual workmanlike fashion.
Federer's draw is about to get a lot more difficult, however. He'll face Australian phenom Bernard Tomic in the next round before a potential meeting with big-hitting Canadian Milos Raonic. It's a tough road to the title.
Not to be outdone, Murray took down Joao Sousa in three sets, dropping just eight games. He's playing with a lot more confidence now that the major-title monkey is off his back, and he remains on a semifinal collision course with Federer.
He faces an interesting matchup in the third round against Ricardas Berankis, who crushed No. 25 seed Florian Mayer on Day 4. Even though it's a match that Murray should win, it probably won't be as easy as it looks on paper.
As long as Murray—who's cracked 53 winners in his first two matches—remains aggressive, he should be able to reach the semifinals for the fourth straight year Down Under. That's the type of extended dominance it takes to get in the same class as Federer and Novak Djokovic.
No Issues for Serena
Any concerns about Williams' ankle after a brief scare in her previous match were quickly put to rest as she rolled past Garbine Muguruza in just over an hour. The dominant American dropped just two games and only faced one break point.
She's been in amazing form ever since a shocking first-round loss at the French Open last season. Now that her ankle appears to be a non-issue, it's impossible to consider anybody else the favorite for the women's title.
No player can beat Williams when she's playing her best tennis—it's really that simple. She will face Ayumi Morita in the next round—it should be another convincing victory—before her first real test, likely against Maria Kirilenko.
