Novak Djokovic won his fourth China Open on Sunday afternoon, dominating Rafael Nadal 6-3, 6-4 in the final and improving his Beijing tournament record to 19-0. Djokovic’s win halted a streak of three straight defeats to Nadal, but couldn’t prevent the Spaniard from ascending to world number one tomorrow when the new rankings come out. That issue was decided on Saturday when Tomas Berdych had to retire with a back injury in his semifinal against Nadal. All Nadal needed to do was reach the final to displace Djokovic from the top rung. Nole took control from the outset, breaking Nadal in the second game and racing to a 3-0 lead. The break was all Djokovic needed to take the first set, as he dropped just two points on his serve. Hitting winners almost at will, Djokovic broke Nadal in the first game of the second set and again served impeccably. He never faced a break point and lost only four points on his serve in the decider, serving it out in just one hour and 27 minutes. For the day Djokovic won 40 of 46 service points, including five aces. “I needed this win today,” Djokovic said. “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.” Since defeating Nadal for the Monte Carlo Masters title in April, Djokovic had lost to the Spaniard in the French Open semifinals, the Rogers Cup semifinals and the U.S. Open final. “I managed to stay tough and not drop my concentration, which I think (happened) in both Montreal and at the U.S. Open in the important moments,” Djokovic said. “I learned my lesson. It was a few very tough and close matches that I lost against Rafa on hard courts, especially the last one in the U.S. Open final.” Nadal was 26-0 on hard courts this year coming into the final and had won 10 titles. “I didn’t see the way to stop him this afternoon,” Nadal said. “This afternoon he was too strong for me. I didn’t play my best match, but he played at a very high level with his serve. I was not able to have any chance when I was returning during the whole match. He had the ball staying very low. It was very difficult to create spin on this ball.” Djokovic improved to 16-22 against Nadal, while winning his fourth title of the year.
