The Indo-Swiss duo of Sania and Martina endured a 4-6, 6-0, 6-10 defeat against the Chinese Taipei pair in the last four stage of the hard-court tournament.
Although the top seeded pair staged a strong fightback to secure the second set, Ching Chan and Jan Chan finally triumphed over their opponents in the Western and Southern Open.
