ZHENGZHOU, China – Seventh seed Han Xinyun crashed out of the Biyuan Cup Women’s Tennis Open, falling in straight sets to Kazakhstan’s Zarina Diyas, 6-2, 6-0.

The other seeds had a much easier time of it, though, with fifth seed Zheng Saisai beating Lu Jia-Jing, 6-2, 6-2, and sixth seed Kurumi Nara of Japan defeating Zhu Lin, 6-4, 7-5.

Arina Rodionova and Liu Chang had a titanic tussle, with both sets going to tiebreaks – and the Australian finishing on top in both, eventually triumphing 7-6(2), 7-6(4).

Elsewhere, Uzbekistan’s Sabina Sharipova beat Kang Jiaqi 6-4, 3-6, 6-4, and in an all-Japanese clash Shiho Akita beat Mayo Hibi 6-2, 6-4.
