NEW YORK (Dispatches) - Rafael Nadal won his third U.S. Open and 16th Grand Slam title with a one-sided victory over South Africa's Kevin Anderson in New York.
The world number one powered to a 6-,3 6-3, 6-4 victory in Sunday's final at Flushing Meadows.
The Spaniard, 31, has now won two Slams in the same year for the first time since 2013, having won the French Open in June.
"It's just unbelievable what happened this year," said Nadal.
The U.S. Open was the last Grand Slam where he was working alongside his uncle Toni, with Carlos Moya taking sole charge of coaching from 2018.
"I can't thank him enough for all the things he did for me," Nadal said of his uncle.
The result means this year's major titles are shared between Nadal, at the French and U.S. Opens, and Roger Federer, at the Australian Open and Wimbledon.
Federer remains at the top of the men's all-time Grand Slam list with 19 titles, three ahead of Nadal, who has now won 10 French titles, three U.S., two Wimbledon and one Australian.

Wu Warns World After First Chinese Boys Slam Title
Wu Yibing served notice to the world that Chinese men's tennis is on the rise Sunday after capturing a milestone Grand Slam boys singles title at the U.S. Open.
The 17-year-old second seed from Hangzhou became China's first boys Slam singles champion by defeating Argentina's top-seeded Axel Geller 6-4, 6-4.
"I think this is showing ourselves and showing the world Chinese boys can be good and better -- and Chinese men."
Wu made his best prior Grand Slam singles run into this year's Australian Open semi-finals and also reached the Wimbledon quarter-finals.
Wu squandered six championship points in the eighth game of the second set before taking the title on his seventh opportunity when Geller swatted a forehand wide after 80 minutes.
