Novak Djokovic defeated Rafael Nadal 6-2, 6-2 Sunday to win his sixth China Open title and improve his record at the tournament to a sterling 29-0. Djokovic had seven aces to none for his Spanish rival, and saved both break points he faced in the match, which was the 45th between the two players. Nadal still leads 23-22 but hasn't beaten Djokovic since the French Open final last year and hasn't prevailed on hard courts since the 2013 US Open final. The top-ranked Serbian player has been so dominant in Beijing, he's only lost three sets in six years. This year, he also only lost 14 games coming into the final, the fewest in his career at an ATP Tour event. In the women's final, Wimbledon runner-up Garbine Muguruza captured her second career WTA Tour title at the China Open Sunday, rallying in both sets to defeat Timea Bacsinszky 7-5, 6-4. Muguruza trailed 5-2 in the opening set before winning five straight games to clinch it, then went down an early break in the second set before coming back yet again. The Spaniard will rise to a career-high ranking of No. 4 Monday, while Bacsinszky will break into the top 10 for the first time. Muguruza struggled after her breakthrough performance at Wimbledon, losing in the second round of the US Open, but she has played some of her best tennis in the past two weeks. She also reached the final last week in Wuhan, retiring in the second set with a left ankle injury while trailing Venus Williams. Wawrinka wins in Japan Switzerland's French Open champion Stan Wawrinka captured his fourth title this year when he beat his good friend Benoit Paire 6-2, 6-4 in the final of the Japan Open Sunday. Wawrinka, in the best form of his life, needed just 65 minutes to win the one-sided final at the Ariake Colosseum, the venue that will stage the tennis competition at the 2020 Tokyo Olympics. The final was played with the roof closed because of the threat of rain and Wawrinka quickly gained control. He wrapped up the opening set after just 26 minutes with three service breaks. The second set was much tighter, Wawrinka had to fight off two break points in the third game but he seized his only opportunity, in the 10th game, to complete a straight-sets win. "I feel great, it's been a really good week for me to win a title again, something always special," said Wawrinka. "You don't win a title every week. It's always difficult when I play a good friend like Benoit. I knew before the match he was struggling a bit physically, but I saw the doctor who told me Benoit was ready to play. "I played my best game today. I felt the ball well and was aggressive. I am very happy to have the trophy tonight." The win gave Wawrinka his 11th career title, the majority of which have come since he won the 2014 Australian Open. His win in Japan was the 30-year-old's fourth this year after he won in Chennai and Rotterdam and at the French Open. Paire was appearing in just his fourth ATP career final and his second this year after winning the Swedish Open in July. — Agencies
