Serena Williams shares the best showing by a wildcard at Indian Wells - reaching the semifinal three years ago - nine years after Martina Hingis made it to the same stage.
Serena Williams is one of six former champions taking part this year, along with Victoria Azarenka, Simona Halep, Maria Sharapova, Elena Vesnina and Caroline Wozniacki.
The last No.1 seed to win the title at Indian Wells was Victoria Azarenka, who took the honours in 2012. Top-ranked Angelique Kerber fell at the last-16 stage last year.
Simona Halep can pull level with Kim Clijsters and Angelique Kerber on 20 weeks spent as World No.1 if she maintains her spot beyond this tournament.
Petra Kvitova awaits the winner of Yulia Putintseva and Alison van Uytvanck in the second round, knowing victory in that second round match will enable her to level her career-best run of 14 consecutive wins.
Martina Navratilova remains the only player to retain an Indian Wells crown, winning in both 1990 and 1991. At 34 years and 136 days in winning that second title, she also remains the oldest winner of the tournament.
Only Lindsay Davenport, on 47 wins, has more Indian Wells match victories than Maria Sharapova (38), with Caroline Wozniacki third on the list (30).
