Sixth seed Samantha Stosur has breezed past American wildcard Irina Falconi 6-0, 6-3 in her second round match at the WTA/ATP Indian Wells tournament.
Australia's number one will face Nadia Petrova in the third round after she also progressed in straight sets beating Lauren Davis 6-3, 6-2.
Her win capped a good day for Australian tennis after Matthew Ebden scored an upset victory over Frenchman Julien Benneteau 2-6, 6-3, 6-2.
Ebden, who is the world number 91 - 58 places below Benneteau - will face Mardy Fish in the third round.
Defending champion and world number Novak Djokovic defeated qualifier Andrey Golubev 6-3, 6-2 in a second-round match.
Djokovic moved through to the third round, where he will face South African Kevin Anderson, who won in a walkover when German Philipp Kohlschreiber withdrew earlier in the day.
"It was a good start," Djokovic said.
"We didn't play a beautiful match. There were a lot of unforced errors but it was the opening match and I am still trying to adjust to this court and get used to the conditions. Hopefully the next match will be better."
World number one Djokovic, who came into Indian Wells last year riding a win streak that he eventually stretched to 41 matches, is now 11-1 on the season.
Elsewhere, former world number one Ana Ivanovic avenged last year's first round loss at Roland Garros by routing Johanna Larsson in straight sets, 6-1, 6-2.
Ivanovic broke Larsson's serve five times, including three times in the opening set. She had three aces and four double faults and posted a 67 per cent success rate on first-serve points in the centre-court match.
Four years ago, Ivanovic won at Indian Wells then went on to capture the French Open title.
Ivanovic advances to the third round, where she will face either Peng Shuai or Ksenia Pervak.
