Roger Federer beats Rafael Nadal in Shanghai

Roger Federer beat world number one Rafael Nadal 6-4 6-3 in the Shanghai Masters final to capture his sixth title of the year.

The 36-year-old Swiss, who has lost only four times in 2017, was again in imperious form as he won in 72 minutes.

It was his fourth win of the year against Nadal and his fifth in succession over the Spaniard.

Federer fired 10 aces, and the 19-time Grand Slam winner's 94th career title cut his deficit against Nadal to 23-15.

It was the 24th meeting in a final between the world's top two, and with the roof again closed because of rain in Shanghai, Federer built a 4-2 lead en route to winning the opening set.

There was little between them in the early exchanges of the second set until the pivotal fifth game.
