Americans Sloane Stephens and Vania King round loser at the $5.535 million BNP Paribas Open.
Stephens outlasted Canada's Aleksandra Wozniak in a marathon 4-6, 7-5, 7-6 (9-7) match that lasted over three hours. The 18-year-old had to overcome 11 double faults to earn her first win of the year.
King ousted Italy's Sara Errani 7-6 (7-3), 6-4 on the hardcourts at the Indian Wells Tennis Garden. Errani converted on 4-of-6 break chances, but was able to win just 51 percent of her service points en route to the loss.
Rising German Mona Barthel spanked the 37-year-old Craybas 6-1, 6-2 in a mere 48 minutes on Wednesday.
The 21-year-old Barthel, who captured her first-ever WTA title in Hobart in January, is rewarded with a second-round match against world No. 1 star Victoria Azarenka.
American wild card Jamie Hampton advanced with a 52-minute 6-0, 6-1 pasting of Slovenian Polona Hercog. The Alabama native is rewarded with a second-round match against former world No. 1 Jelena Jankovic of Serbia. Jankovic was the Indian Wells champ two years ago.
Meanwhile, Aussie Jarmila Gajdosova came from behind to dismiss American wild card Coco Vandeweghe, 4-6, 6-3, 6-3 and Romanian Sorana Cirstea overcame veteran Czech lefthander Iveta Benesova 4-6, 7-5, 7-6 (7-5).
Additional wins came for 41-year-old Japanese Kimiko Date-Krumm, Czech Klara Zakopalova, Swiss Timea Bacsinszky, Spaniard Carla Suarez Navarro, and Kazakhstan's Galina Voskoboeva, who will face eighth-seeded French Open champ Li Na of China on Friday.
The winner of this 12-day event will enjoy a $1 million windfall.
