Novak Djokovic has crushed his age-old rival Rafael Nadal 6-2 6-2 to seal his sixth China Open title.

The world No.1 underlined his superiority in men’s tennis as he thrashed a fading Nadal on Saturday in Beijing for his 29th win at an event he also won in 2009, 2010, 2012, 2013 and 2014.

Djokovic won three of the four grand slam finals this year and shows no signs of slowing down at the end of the season after losing only 18 games in his romp to the Chinese title.

Djokovic put Nadal under pressure from the start with a thunderous opening rally, which the Spaniard lost, and the world No.8 then shanked a forehand high into the air to give up the first break point.

Nadal had break points in the sixth game but Djokovic held firm, gaining his second break in the seventh game when his Spanish opponent volleyed into the net with the court at his mercy.

Nadal called the trainer early in the second set for treatment to his right foot, and when Djokovic broke to go 2-1 ahead the 14-time grand slam winner’s challenge looked shot.

An instinctive lob over the stranded Nadal put Djokovic on his way to a second break and 4-1 lead, and after passing up two match points at 5-2, he finally sealed it with an ace for his rapturous Chinese fans.

In the longest rivalry in men’s tennis history, Djokovic moves to 22 won, 23 lost – but with seven victories out of their last eight meetings, including this year’s French Open quarter-finals.

With his 29th victory at the China Open, 10-time slam champion Djokovic is also closing on Nadal’s record for winning starts to a tournament after he racked up 31 before his first defeat at the French Open.
