体坛英语新闻：Nadal, Djokovic claim group wins at ATP World Tour Final

LONDON, Nov. 5 (Xinhua) -- World No. 1 Rafael Nadal breezed past fellow Spaniard David Ferrer while Novak Djokovic of Serbia labored to defeat Roger Federer of Switzerland in their first group matches at the ATP World Tour Finals here on Tuesday.

Nadal beat Ferrer 6-3, 6-2 in 74 minutes in Group A and took a sweet revenge on his loss to Ferrer in the Paris Masters semifinals on Saturday.

Reigning champion Dokovic, who overcame Federer in the semifinals in Paris three days ago, fought off tough challenge from the six-time winner in the second set, but managed a win again 6-4, 6-7 (2-7), 6-2.

"I played a little calmer than other the day," said Nadal. "In my opinion, he didn't have the chance to hit a winner as easy as he did three days ago."

The 27-year-old Nadal will qualify for the semifinals, should he beat Stanislas Wawrinka of Switzerland in two sets or if he beats Wawrinka and Ferrer defeats Tomas Berdych.
