Novak Djokovic marches on at Shanghai Masters

Novak Djokovic made it 70 wins in 2015 as he cruised past 15th seed Feliciano Lopez and into the Shanghai Masters quarter-finals.

The world number one is enjoying his most productive season since 2011 ” when he won 10 tournaments ” with eight titles to his name already and he remains on track to make it nine after Thursday’s 6-2 6-3 triumph.

Djokovic was rarely troubled by his Spanish opponent in the third-round encounter, only facing three break points in the whole match and hitting 22 winners, while unforced errors cost Lopez.

Victory came in just 71 minutes for the top seed, but despite his dominant win he still believes he can make improvements ahead of the ATP World Tour Finals.

“I was always brought up that way and taught to always look for some room for improvement and I still believe there are shots in my game that can be better,” he said. “And I think that’s one of the things that keeps me going, it motivates me to play more.

Next up for the Serb is Bernard Tomic after he beat Richard Gasquet 6-3 6-7 (1-7) 6-4, while a potential semi-final with Andy Murray remains in the offing after the Scot came from a set down to beat John Isner.

The American edged a tight opening set in a tie-break, but Murray came fighting back to break once in both of the next two sets as he triumphed 6-7 (4-7) 6-4 6-4.

He levelled the match thanks to a break late in the second before saving two break points to restore parity. In the decider Isner was under pressure in his second service game, before Murray got the crucial break four games later.

Murray will meet Tomas Berdych in the last eight after the fifth seed swept aside Richard Gasquet 6-3 6-3.

Former finalist Rafael Nadal registered his first win over a top-10 player in six attempts with a comprehensive 6-3 7-6 (7-3) win over Milos Raonic, the 14-time grand slam winner’s forehand working superbly.

Stan Wawrinka will be the world number seven’s next opponent after he prevailed in a near three-hour battle with Marin Cilic, the Swiss holding his nerve to win 7-5 6-7 (7-9) 6-4 against the big-serving Croat.

The fourth quarter-final will see Jo-Wilfried Tsonga face Kevin Anderson, the latter’s 7-6 (12-10) 7-6 (7-3) success over Kei Nishikori causing the upset of the day.

Meanwhile, Tsonga ended Roger Federer’s conqueror Albert Ramos’ run in the tournament as he fought back to progress 6-7 (5-7) 7-5 6-4.
