The 22-year old Serb, the third seed, will next face either Frenchman Gael Monfils or Radek Stepanek of Czech Republic.

"I felt so good on the court that all the shots I hit transformed into winners," said Djokovic, who advanced to his 10th final of the year. "There is not much to say about today's performance, except it was perfect, exactly the way I wanted."

Djokovic, who has a 6-14 record against Nadal but beat him for the second consecutive time, was dominant from the start and didn't face a single break point on his way to victory.

"I was aggressive and I took the early control of the match over my opponent and it paid off," Djokovic said. "I was hitting winners from all over the court.

Winning 83 percent of the points played on his first serve, Djokovic, who had 31 winners, took the first set after claiming four games in a row.

The former Australian Open winner, who has a 4-5 record in finals this year, pumped his fist when he broke Nadal to love to lead 4-2 with a backhand winner down the line. He didn't lose a point in the next two games, overwhelming his rival with powerful groundstrokes and subtle drop shots.

Nadal, who lost 14 straight points on his serve and seven consecutive games overall, was broken at love for the third time in a row when Djokovic hit another forehand down the line for a 2-0 lead in the second set.

Djokovic, who defeated top-ranked Roger Federer in the Swiss Indoors final last week, twisted his ankle in the seventh game after firing a crosscourt backhand passing shot but kept his serve and closed out the match with a forehand winner.

Nadal returned to competition in October after a month off with a pulled stomach muscle. He reached the semifinals in Beijing, then the final in Shanghai where he lost to Nikolay Davydenko. His last title victory on the tour came in May at the Rome Masters.

"I finished this tournament much better than I started," said Nadal, who defeated defending champion Jo-Wilfried Tsonga in the quarterfinals after two difficult three-set matches in previous rounds. "The confidence will not go away because I lost 6-2, 6-3 to Djokovic."

Nadal and Djokovic are among the eight players who will face off from Nov. 22-29 in London at the ATP World Tour Finals. The 23-year-old Nadal is also expected to play the Davis Cup final when defending champion Spain will host the Czech Republic on clay in Barcelona from Dec. 4-6.
