China's Wang Xinyu was eliminated from Indian Wells on Sunday with a third-round loss to American fourth seed Jessica Pegula.

World No. 42 Wang served three double faults and saved just two of seven break points en route to a 6-2, 6-1 defeat.

Pegula, who is aiming for her eighth career title in the WTA 1000 event, put 78 percent of her first serves in play as she set up a round-of-16 meeting with either American Danielle Collins or Ukraine's Elina Svitolina.

Meanwhile, Chinese pair Xu Yifan and Yang Zhaoxuan bowed out of the women's doubles with a 6-3, 4-6, 10-6 loss to Ukraine's Lyudmyla Kichenok and American Sofia Kenin.

Kichenok and Kenin served three aces and won 77 percent of points on their first serve to take the match in an hour and 28 minutes.

The eighth-seeded pair will meet either Katerina Siniakova and Taylor Townsend or Beatriz Haddad Maia and Laura Siegemund in the quarterfinals.
