Nadal and Federer cruise through, Del Potro masters Zverev in Shanghai
Rafael Nadal cruised to a 14th consecutive victory at the expense of Fabio Fognini and Roger Federer also eased to a straight-sets winÂ to reach the quarter-finals of the Shanghai Masters on Thursday.
World number one Nadal has not been beaten since Nick Kyrgios knocked him out of theÂ Western & Southern Open in August and took just over an hour to dispatch Fognini 6-3 6-1.
Federer, playing his first tournament since losing toÂ Juan Martin del Potro in the quarter-finals of the US Open, later breezed through with a 6-4 6-2 win overÂ Alexandr Dolgopolov.
The Swiss great, eyeing a secondÂ Shanghai Masters title, broke in the first game of the match and twice in the second set to march into the last eight.
Del Potro struck a blow for experience over youth, ousting third seedÂ Alexander Zverev 3-6 7-6 (7-5) 6-4. The Argentine will now take onÂ Viktor Troicki, who knocked out 12th seed John Isner.
Marin Cilic, the fourth seed, was a 7-6 (7-1) 6-4 winner againstÂ Steve Johnson, whileÂ Grigor Dimitrov got past Sam Querrey to set up an encounter with Nadal.Â
Richard Gasquet andÂ Albert Ramos-Vinolas also reached the quarter-finals by beatingÂ Gilles Simon andÂ Jan-Lennard Struff respectively.Â
NADAL DISHES OUT MORE PUNISHMENT TO FOGNINI
Fognini was on Wednesday given aÂ $96,000 fine and aÂ suspended grand slam ban forÂ verbally abusingÂ a female umpire at the US Open last month.
The Italian was in for some on-courtÂ punishment a day later, Nadal turning on the style yet again as he eyes a third consecutive title following his China Open and US Open triumphs.
Top seed Nadal made only four unforced errors in another masterclass, hardly giving Fognini a look-in with a superb service display and breaking four times after piling the pressure on his unseeded opponent.
Nadal beat Dimitrov in three sets at the semi-final stage in Beijing and can expect a sterner test from the sixth seed.
FEDERER IN CRUISE CONTROL
Federer had won all four of his previous matches againstÂ Dolgopolov and his perfect record against the Ukrainian was never really under threat.
Dolgopolov was the only qualifier to reach round three, but Federer ensured he would go no further with a commanding performance.
The second seed faced only one break point and saved that, going on to serve out the first set in the same game and thenÂ easily claiming the second toÂ progress.
Federer will come up againstÂ Gasquet in the quarter-finals, an opponent he has lost only twice to in 17 encounters. HeÂ was last beaten by the Frenchman six years ago.
DEL POTRO SETTING 2018 GOALS
Del Potro's victory over Zverev was his fourth over a top-10 opponent this year and the 16th seed already has an eye on making further strides next year after spending so long off the circuit due to injury during his career.
The 2009 US Open champion said: "One of my goals for the next year is just to play a whole year â€“Â around 20, 22 tournaments would be great for me,
"If my level continues improving, I will get closer to the top guys. But it's not easy. I have made a big effort after all my injuries to play tennis, but I think I'm doing well."
