World No. 1 Novak Djokovic extended his hot streak in China as he blazed past Martin Klizan at the Shanghai Masters Wednesday with Andy Murray and Stan Wawrinka snapping at his heels. The two-time champion brushed Klizan aside 6-2, 6-1 to set up a clash with Feliciano Lopez or Dominic Thiem as he seeks to add to this year's haul of eight titles, including three of the four Grand Slams. The Serb lifted the China Open trophy for the sixth time Sunday and he said a surge of confidence after what he calls his best season yet made him very tough to beat. "Considering the fact that I've won so many matches this year and tournaments, probably the best season of my life definitely, anywhere I go I'm confident," said Djokovic, after raising his win-loss record to 69-5 this year. Murray, another two-time winner at Shanghai's Qi Zhong Stadium, also zipped past Steve Johnson 6-2, 6-4 and French Open champion Wawrinka beat Viktor Troicki 7-6 (7/3), 6-3. After Roger Federer's shock loss to 70th-ranked Albert Ramos-Vinolas late Tuesday, there were no banana-skins for Djokovic, Wawrinka or Murray, who was returning to action following a four-week break. Outspoken Australian Nick Kyrgios flirted with a 28-day ban after he was slapped with his second code violation in as many matches during his 1-6, 6-4, 6-4 loss to Japan's Kei Nishikori. But Australian No. 1 Bernard Tomic reached the third round when he beat David Ferrer 6-4, 6-2 — denting the Spaniard's hopes of reaching the World Tour Finals in London. Kyrgios was again at the center of controversy when he received a code violation for smacking away a loose ball and nearly hitting a line judge — a day after he was fined $1,500 for an audible obscenity. Jankovic, Stosur advance Jelena Jankovic and Samantha Stosur advanced to the quarterfinals of the Hong Kong Open Wednesday, both winning in straight sets. Jankovic, a former top-ranked player from Serbia, beat Anastasia Rodionova of Australia 6-0, 6-2. Stosur defeated Monica Puig of Puerto Rico 6-4, 6-4. Stosur will next face Heather Watson, who beat Taiwanese qualifier Lee Ya-hsuan 6-0, 6-7 (5), 6-4. Sixth-seeded Daria Gavrilova also advanced, beating Lara Arrubarrena of Spain 7-6 (4), 6-1. — Agencies
