(Updates with Nadal's match)
Spain's Rafael Nadal coasted into the U.S. Open fourth round with an impressive 6-4, 6-3, 6-3 victory Saturday over Croatia's Ivan Dodig.
The No. 2 seed dominated the rallies from the outset, breaking his opponent's serve in the third game en route to taking the first set.
The 2010 champion then earned two service breaks in each of the final two sets to wrap up the lopsided victory.
Nadal, who has made a stunning comeback from a knee injury that kept him out of action for several months last year, has a 56-3 record this season and can reclaim the No. 1 ranking by winning the tournament.
The Spaniard will seek to remain undefeated on hard courts this season when he takes on either American John Isner or Germany's Philip Kohlschreiber in fourth-round action on Monday.
In other results Saturday, fourth-seeded Spaniard David Ferrer topped Kazakhstan's Mikhail Kukushkin 6-4, 6-3, 4-6, 6-4 to advance to the fourth round.
In women's third-round play, No. 2 seed Victoria Azarenka of Belarus rallied from a set down to defeat Frenchwoman Alize Cornet 6-7 (2-7), 6-3, 6-2. EFE
