Serena Williams has moved into the third round of the Australian Open with a 6-2, 6-0 win over Garbine Muguruza of Spain on Thursday.

Williams injured her right ankle in her first-round match against Edina Gallovits-Hall, falling to the court, but still managed to complete a 6-0, 6-0 victory.

She had a private practice session on Wednesday and didn't seem bothered by the injury in Thursday's 75-minute match.

With the win, Williams stayed on track to win her third Grand Slam in a row - she also won last year's Wimbledon and U.S. Open - and a chance to complete the second "Serena Slam" of her career - holding all four majors at the same time.
