The 31-year-old world number one was barely threatened by his Australian opponent in Beijing as the 22-year-old struggled to regain his composure after losing his cool when a line call was wrongly judged against him in the opening game of the match.
"He probably didn't play his best today, but I thought I really served well and didn't give him much rhythm", said Kyrgios, who is going after his fourth ATP title, but first this year.
The first four or five games were hotly contested and of sublime quality, but Nadal's returning, which was vastly better than it was in a loss to Kyrgios this summer in Cincinnati, and clutch serving wore down Kyrgios, who also let a bad call in the first game fester in his mind.
Nadal, appearing in his 110th career final, maintained his dominance during the second set breaking the world No 19 twice before wrapping up the match with a comfortable service hold to extend his match winning streak to 12. I'm very excited for doubles obviously.' He still plans to play in Antwerp, Basel, Paris Masters and provided he qualifies, the World Tour Finals in London as well.
"To play every single day, it was just after every match you had to forget about what happened and be on the present again".
