Rafael Nadal and Roger Federer breezed into the quarter-finals of the Shanghai Masters on Thursday and Juan Martin del Potro defeated racquet-smashing Alexander Zverev.
World number one Nadal blew away Fabio Fognini in 63 minutes and plays sixth seed Grigor Dimitrov as he pursues one of the few tournaments to have eluded him.
Timeless rival Federer was even faster, dismissing Ukrainian qualifier Alexandr Dolgopolov 6-4, 6-2 in 61 minutes.
The 31-year-old Spaniard Nadal, fresh off the back of triumphs at the US Open and China Open, anticipates a tough encounter against the Bulgarian Dimitrov.
“I played a very good match, I don t know how many mistakes I made, but very few,” said the 16-time Grand Slam winner and top seed in Shanghai.
“I have a tough match against Grigor and know I will have to play my best… but I am playing well.”
Nadal, enjoying a late-career flourish, defeated good friend Dimitrov on his way to winning the China Open on Sunday, his sixth title of the season.
