Kerber stunned, Nadal advances

Montreal, August 10
The punishing serve that propelled Karolina Pliskova to the top of the tennis world last year proved ineffective against Kiki Bertens at the Rogers Cup on Wednesday as the Dutchwoman cruised to a 6-2 6-2 victory. The ninth-seeded Czech failed to record a single ace in the second-round battle but committed eight double faults and was broken seven times by the defensive-minded Bertens.
Bertens will next meet eighth seed Petra Kvitova, who advanced past Estonian Anett Kontaveit 6-3 6-4.
Wimbledon champion Angelique Kerber fell 6-4 6-1 to Alize Cornet of France.
The unseeded Maria Sharapova made quick work of fellow Russian Daria Kasatkina during their first meeting with a convincing 6-0 6-2 win.
In Toronto, Rafa Nadal was made to wait before his second-round match due to several rain delays but did his part to put the schedule back on track with a speedy 6-2 6-3 win over Frenchman Benoit Paire on Wednesday.
Nadal will face Stan Wawrinka in the Round of 16 after the Swiss rallied to beat Hungarian Marton Fucsovics 1-6 7-6(2) 7-6(10).
In earlier action, a solid-serving Novak Djokovic kept his bid for a fifth Rogers Cup title alive with a 6-3 6-4 win over Canadian wildcard Peter Polansky.
