California: China's Peng Shuai and former world No. 1 Ana Ivanovic both won in straight sets on Wednesday in the second round at the Mercury Insurance Open, while Germany's Julia Goerges made an unexpected early exit.
Peng won 6-1, 6-3 against Australia's Anastasia Rodionova to set up a clash with Italy's Sara Errani. Serbia's Ivanovic beat Japan's Ayumi Morita 6-1, 7-6 (5), avenging a first-round, straight sets loss last week and setting up a match against another Italian, Alberta Brianti.
The shock of the day was provided by American teenager Sloane Stephens, who had an upset 6-3, 7-5 win over seventh-seeded Goerges despite a potentially costly and embarrassing mistake.
