Montreal: Sania Mirza and Cara Black spanked Raquel Kops-Jones and Abigail Spears in just 52 minutes to seal a semi-final berth at the Rogers Cup, here.
The fourth seeded Indo-Zimbabwean pair knocked out the sixth seeded American team 6-2, 6-1 in the lop-sided quarterfinal contest.
Sania and Cara converted six of the 10 break chances in the match in which they won 52 points to 27 of their rivals.
World No. 1 Serena Williams and sister Venus will renew one of sport’s great sibling rivalries after posting quarter final wins to set up a showdown on the Montreal hard courts.
Serena kept her title defence on track rallying for a 4-6, 7-5, 7-5 win over Caroline Wozniacki while Venus booked her place in the final four by beating 14th seeded Spaniard Carla Suarez Navarro 4-6, 6-2, 6-3.
It will mark the 25th time the sisters have squared off and first since a 2013 semi-final clash in Charleston that Serena won.
The other semi will pit third seed Agnieszka Radwanska against Ekaterina Makarova.
Poland’s Radwanska, the third seed, advanced with a dominant 6-2, 6-2 win over Belarus’ Victoria Azarenka. Makarova beat American qualifier Coco Vandeweghe 6-1, 4-6, 6-1. (Agencies)
