MELBOURNE, Jan. 15 (UPI) -- Serena Williams, slowed momentarily by an ankle injury, didn't lose a game Tuesday in her first-round match at the Australian Open.
Williams, seeded third and the winner of the last two Grand Slam events, pasted Edina Gallovits-Hall 6-0, 6-0 in 54 minutes. Williams rolled her right ankle in the fifth game of the match but after a short medical timeout returned to the court and took the next eight games.

Defending champion and world No. 1 Victoria Azarenka won 57 percent of the points when receiving serve in defeating Monica Niculescu. She won 70 percent of the points overall in the first set in establishing control of the match.
