Joint/Xu advanced with a straight-sets win over Muhammad/Stollar, while Piter/Tjen produced the stronger recent result by upsetting the second seeds Jiang/Zhang in a three-set match featuring a decisive super-tiebreak. Tjen, ranked around No. 35 in singles, brings momentum from that doubles victory despite a singles round-of-16 exit the same week. The Australian-Chinese pairing has solid prior hard-court experience, but the Indo-Polish duo’s ability to close out higher-ranked opponents shapes current trader consensus around the closely matched contest. No notable injuries or withdrawals affect the draw.

Joint/Xu advanced with a straight-sets win over Muhammad/Stollar, while Piter/Tjen produced the stronger recent result by upsetting the second seeds Jiang/Zhang in a three-set match featuring a decisive super-tiebreak. Tjen, ranked around No. 35 in singles, brings momentum from that doubles victory despite a singles round-of-16 exit the same week. The Australian-Chinese pairing has solid prior hard-court experience, but the Indo-Polish duo’s ability to close out higher-ranked opponents shapes current trader consensus around the closely matched contest. No notable injuries or withdrawals affect the draw.
