Australian Jelena Dokic lasted just nine minutes in her opening-round match at Indian Wells before withdrawing due to a wrist injury.
Her withdrawal sent Argentine opponent Gisela Dulko straight through to a second-round match-up with number two seed Maria Sharapova.
In the men's draw Australian Matthew Ebden triumphed 6-1, 4-6, 6-4 in his opening match against Russian Igor Kunitsyn.
Elsewhere wildcard Sam Querrey defeated fellow American Tim Smyczek 7-6 (7-1), 6-4, Poland's Lukasz Kubot beat Ivo Karlovic, of Croatia, 6-4, 6-2 and Italy's Andreas Seppi rallied to defeat Olivier Rochus, of Belgium 4-6, 6-3, 6-4.
Irina Falconi and Johanna Larsson also advanced to the women's second round thanks to opponents retiring injured.
Sweden's Larsson was 4-1 ahead in the first set when qualifier Greta Arn of Hungary retired from their match with a neck injury.
Larsson will face former world number one Ana Ivanovic, who is seeded 15th, in the next round.
Arn reached the third round of the Australian Open and the semi-finals in Monterrey, Mexico, last month, where she lost to Romania's Alexandra Cadantu.
American wildcard Falconi advanced after Alexandra Dulgheru withdrew from their match with a right knee injury.
Dulgheru won the first set 6-4 and was trailing 5-2 in the second when she pulled the plug.
Sweden's Sofia Arvidsson swept past Eleni Daniilidou of Greece in her opening match 6-4, 7-6 (7-4).
The 28-year-old Arvidsson kept her unforced errors down to a minimum and won 65 per cent of her second serve points in the one hour, 55 minute match.
