Novak Djokovic Beats Rafael Nadal for fourth China Open Victory

Novak Djokovic won his fourth China Open title in five years overnight, prevailing 6-3 6-4 in the final against Rafael Nadal who will replace him as the men's world number one today.

Nadal had to reach the final in the tournament to displace Djokovic from the top ranking and the issue was put to rest on Saturday when Tomas Berdych retired with a back injury in his semi-final against the Spaniard.

"I needed this win today," Djokovic told reporters. "I really wanted to get my hands on the trophy and win against Nadal, who has been the best player so far in 2013.

"It's very important for my confidence. It's very important mentally and emotionally for me."

The 26-year-old Djokovic stamped his authority on the title match early, racing to a 3-0 lead and never allowing the Spaniard, who went into the match unbeaten on hard courts this year, to stage a comeback.

The Serb broke Nadal, who has won 10 tournaments and added over $10 million in prize money in 2013, in the first game of the second set - hitting winners almost at will.
