MELBOURNE, Australia -- Serena Williams tumbled to the court and needed a medical timeout in the first set for treatment on her right ankle. Once she got up, it was all over for Edina Gallovits-Hall.

Williams routed Gallovits-Hall 6-0, 6-0 in the first round of the Australian Open on Tuesday (Australia time) despite the scary sequence in the first part of the match.

The No. 3-ranked Williams is favored to win the season's first major, rolling into Melbourne Park with 35 wins in her previous 36 matches, including titles at Wimbledon, the London Olympics and the U.S. Open. But the injury could be a significant setback as she seeks a third consecutive Grand Slam title.

Williams said there was pain and swelling in her ankle, and X-rays were an option, but she wanted to leave any decisions about treatment for a few hours. She gets a day off before her second-round match Thursday.

"Oh, I'll be out there," she said. "I mean, 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."

Defending champion Victoria Azarenka also advanced, coming back from a break down in the second set to beat Monica Niculescu 6-1, 6-4 at Rod Laver Arena.

Azarenka's win was sandwiched between matches on the same court involving two of the main contenders for the men's title. No. 3 Andy Murray won his first Grand Slam match as a major champion, beating Robin Haase of the Netherlands in straight sets, and No. 2 Roger Federer fended off Benoit Paire of France 6-2, 6-4, 6-1.

Also advancing were No. 13 Milos Raonic of Canada, who beat Jan Hajek 3-6, 6-1, 6-2, 7-6 (0), No. 17 Philipp Kohlschreiber, No. 21 Andreas Seppi and No. 25 Florian Mayer.

In a record for the Australian Open, 42-year-old Kimiko Date-Krumm upset No. 12-seeded Nadia Petrova of Russia 6-2, 6-0 to become the oldest woman to win a singles match at the tournament.

In other women's matches, former No. 1-ranked Caroline Wozniacki won the last six games to beat Sabine Lisicki of Germany 2-6, 6-3, 6-3, and No. 16 Roberta Vinci and No. 17 Lucie Safarova also moved on.

American teenager Sloane Stephens beat Simona Halep of Romania 6-1, 6-1.

Also, No. 14 Maria Kirilenko had a 6-4, 6-2 win over American Vania King, and China's Peng Shuai beat Canada's Rebecca Marino 6-3, 6-0.
