Djokovic advances

Four-time champion Novak Djokovic and top-seeded Rafael Nadal advanced to the third round of the rainy Rogers Cup on Wednesday in Toronto. Djokovic, coming off his fourth Wimbledon title, beat Canadian wild-card Peter Polansky 6-3, 6-4. The Serb had seven aces and never faced a break point in the 1-hour, 25-minute match that just beat the afternoon rain. Nadal, playing for the first time since a five-set loss to Djokovic in the Wimbledon semifinals, topped France’s Benoit Paire 6-2, 6-3 at night after a series of rain delays. Greece’s Stefanos Tsitsipas set up a match against Djokovic, knocking off seventh-seeded Dominic Thiem of Austria, 6-3, 7-6 (6). Nadal will face Stan Wawrinka of Switzerland, a 1-6, 7-6 (2), 7-6 (10) winner over Marton Fucsovics of Hungary. Second-seeded Alexander Zverev of Germany beat American Bradley Klahn 6-4, 6-4, and fourth-seeded Kevin Anderson of South Africa edged Russia’s Evgeny Donskoy 4-6, 6-2, 7-6 (0). American John Isner, the No. 8 seed, beat France’s Pierre-Hugues Herbert 7-6 (3), 6-2. Italy’s Fabio Fognini, the No. 14 seed, fell out with a 6-3, 7-5 (14) loss to Canada’s Denis Shapovalov. Karen Khachanov of Russia beat 12th-seeded Pablo Carreno Busta of Spain 6-4, 7-6 (3); Ilya Ivashka of Belarus topped American Ryan Harrison 7-6 (5), 6-4; and American Frances Tiafoe edged Canada’s Milos Raonic 7-6 (4), 4-6, 6-1. Juan Martin del Potro of Argentina withdrew because of a left wrist injury. Del Potro, who had a bye in the first round after reaching the Los Cabos final last week, was set to play Robin Haase of the Netherlands. Haase instead played Mikhail Youzhny, beating the Russian 7-5, 6-2.
