Strong performances on the ITF Circuit this year have seen Wang close in on a Top 50 debut, which she could secure with a deep run in Dalian. However, she was given an unexpectedly stern examination against lucky loser Han before finishing strongly to close out a 6-3, 1-6, 6-1 victory.

Grace Min will meet her in the last eight after she upset No.6 seed Jana Cepelova, 6-4, 6-3. This was not the afternoon’s only upset, either; Aleksandra Krunic knocked out No.3 seed Duan Ying-Ying, 6-2, 3-6, 6-1, while Wang Yafan defeated Tamira Paszek, the No.4 seed, 6-2, 7-6(2).

Also advancing was last year’s runner-up, Julia Glushko, who fought back to see off qualifier Peangtarn Plipuech, 4-6, 6-3, 6-2.
