Shanghai Masters | Roger Federer, Rafael Nadal enter quarter-finals

Nadal dominated the proceedings from the outset and opened up a 3-0 lead before taking the set 6-3 in a 31-minute contest. In the second set, the left-hander broke immediately and despite the Italian earning two break point opportunities at 1-3 to get back on serve, Nadal quickly turned them away and went on to close out the game in 62 minutes. This is Nadal's fourth quarter-final entry in Shanghai as he pursues his first title at the event.

Roger Federer, too, is right on track for a second Shanghai Masters title after securing a straightforward 6-4, 6-2 win against Dolgopolov. The Swiss took three of his seven break opportunities against Dolgopolov and faced just one break point before winning the first set 6-4. But when the Ukrainian made an error to go down a break point at 2-2 in the second set, the 19-time Grand Slam champion hardly broke a sweat after that and closed out the game to enter the last eight.

Bulgaria's Grigor Dimitrov improved his chances of reaching the ATP World Tour Finals with a straight-set win over American Sam Querrey. Dimitrov, ranked ninth in the world, won the match 6-3 7-6 (7-3). Similarly, fourth seed Marin Cilic won 7-6 (7-1) 6-4 against Steve Johnson, setting up a last-eight match against Spain's Albert Ramos-Vinolas, who beat Jan-Lennard Struff in the round of 16.
