INDIAN WELLS, Calif. (AP) Simona Halep is on track to retain her No. 1 world ranking after defeating Wang Qiang of China 7-5, 6-1 in the fourth round of the BNP Paribas Open.
Halep improved to 17-1 this year and needs only to reach the final to stay at the top. If not, Caroline Wozniacki, who beat Halep in the Australian Open final, could replace her if the Dane wins the title. Halep and Wozniacki are the only former Indian Wells winners left in the women’s draw.
Next up for Halep is Petra Martic of Croatia, who beat Marketa Vondrousova of the Czech Republic 6-3, 7-6 (4) on Tuesday.
American teenager Amanda Anisimova’s run of success ended in a 6-1, 7-6 (2) loss to No. 5 seed Karolina Pliskova of the Czech Republic.
