NEW YORK, Aug 31: World No 1 Roger Federer and chief rival Rafael Nadal began their march towards a US Open collision with straight-set victories on Wednesday.
Federer hammered Wang Yeu-tzuoo of Taiwan 6-4, 6-1, 6-0 in first-round action on Arthur Ashe Stadium, while second seed Nadal crushed former finalist Mark Philippoussis 6-4, 6-4, 6-4.
The duo have contested the last two Grand Slam finals and are favourites to meet in the championship match on Sept 10.
Needing just 100 minutes to advance, Australian Open and Federer lost to Nadal in the French Open final but beat him at Wimbledon.
A day after rain wiped out nearly all of the scheduled matches, large crowds at Flushing Meadows welcomed the tennis despite gloomy skies and the constant threat of rain.
In the women's draw, top seed Amelie Mauresmo completed her rain-suspended first-round match with Kristina Barrois, defeating the 131st-ranked German qualifier 6-1, 7-5.
Third seed Maria Sharapova blasted 10 aces and never lost her serve to crush 17-year-old Michaella Krajicek 6-3, 6-0 in just 59 minutes.
Also advancing to the second round were Andy Roddick, Lleyton Hewitt and David Nalbandian on the men's side, and Martina Hingis and Serena Williams on the women's.
Federer, gunning for his third straight US Open crown, hit seven aces and kept Wang off balance by winning 90 percent of his first serve points.
Nadal wasted little time hitting his stride, pumping his fist and roaring on each key point against 1998 runner-up Philippoussis, a hard-serving wildcard entry from Australia.
Second-ranked Nadal Spaniard committed just 10 unforced errors while breaking Philippoussis's serve once in each set.
Nadal, who has never advanced past the third round of the Open, set the tone for the match by breaking Philippoussis in the opening game of the match.
Mauresmo opened the day up a set but down 5-2 in the second before winning all five games against an error-prone Barrois to set up a second-round affair against American Meghann Shaughnessy.
Marat Safin, the 2000 champion, set up an intriguing second-round showdown with Nalbandian after a four-set victory over Czech Robin Vik.
Argentine Nalbandian, the fourth seed, was pushed to the distance by German Michael Berrer before prevailing 6-2 in the fifth.
Australian Hewitt, Safin's successor as champion in 2001, eased to a 7-5, 6-4, 6-3 win over Spaniard Albert Montanes.
