World No. 1 Novak Djokovic played almost flawless tennis to defeat Czech Tomas Berdych 6-0, 6-2 Sunday night in winning his fifth China Open and improving his record to 24-0 in Beijing. Djokovic did not drop a set all week in adding to the trophies he collected in 2009, 2010, 2012 and 2013. The title was the Serb’s ATP Tour-best fifth of the year and ran his head-to-head mark to 16-2 against No. 8-ranked Berdych. Djokovic gave every indication of pulling off a double-bagel scoreline when he served at 6-0, 5-0, but Berdych, with vociferous encouragement from the crowd, dug in and got the face-saving break. The Czech held at love in the next game before Nole closed it out on his serve, concluding the match in just 66 minutes. “This has been, in the circumstances, probably the best performance of any final in my career,” Djokovic said. “It was incredible. Incredible. Especially against Tomas, who has a big game and is already an experienced player. It was 6-0, 5-0 in under an hour. Everything I tried worked. To be proud of the performance is the least I can say of how I played tonight. I have played some great finals, had some convincing wins, some straight-set wins against top rivals. But with this kind of performance and with this domination result-wise, I mean it’s never happened.” Djokovic hit 19 winners to nine for Berdych, and committed just nine unforced errors to his opponent’s 12. Djokovic won 57 points, Berdych 30. “I met somebody in the final who I’ve never seen before,” said Berdych, who won the Beijing title in 2011. “The way that he performed today was really outstanding. There is really not much I can add to that because, really, I was just swept off the court. I just said to my coach now that I probably played over 700 matches in my career, and I met guys like Andre, Roger, all those probably in their best times. But I have never, ever experienced anything like that.” Despite the loss, Berdych, by reaching the final, moved up to No. 7 in the Race to London, the ATP World Tour Finals featuring the top eight points leaders for the year.
