Rafa is looking to clinch his third Grand Slam tournament this season. However, there is a long way to go: He could meet big-serving Croat Ivo Karlovic, the number 13 seed, in the third-round with a potential quarter-final clash with David Nalbandian. In the semis he could face Spain's David Ferrer, the number four seed

Second seed Federer, gunning for his fifth straight title, is up against 114th-ranked Maximo Gonzalez of Argentina.

Awaiting the Swiss in the last four is Serbian Novak Djokovic, the reigning Australian Open champion and a runner-up finish in Flushing Meadows last year.

In the first round, Djokovic, the number three seed, drew Frenchman Arnaud Clement, who reached the quarter-finals at Wimbledon in July

RAFA POWERS ON AT THE US OPEN

Rafa Nadal overpowered American qualifier Ryler DeHeart 6-1 6-2 6-4 on Thursday to reach the third round of the U.S. Open.

Top-seeded Rafa, who was pushed to two tiebreakers by German qualifier Bjorn Phau in the first round, blasted his way past DeHeart, losing serve just once in the battle of left-handers that closed the fourth day of play.

The 22-year-old Spaniard was in total command, landing 70 percent of his first serves and facing just one break point from the DeHeart, who cashed it in and led 3-0 in the third set

Rafa brought the 24-year-old American, ranked 261 and playing in his first grand slam, back to earth by winning the next five games and then closing out the match with a sizzling forehand winner to serve out his victory.

"The important thing was I had to come back in the third set and I'm happy with the victory," said Rafa.

The Spaniard had complained of fatigue after his opening match on Monday, a hangover from a busy season that included title runs at the French, Wimbledon and Beijing Olympics.

He was full of energy against DeHeart on the Arthur Ashe Stadium court, needing only 19 minutes to claim the first set and less than an hour to take a two-sets lead.

"I forgot a little bit about tennis," the revitalised Spaniard said about his time off. "I played golf on Tuesday.

"Now I'm in the third round. I'm happy. For me it's a very important tournament here," said Rafa, who was eliminated in the fourth round last year.

Rafael winner of 40 of his last 41 matches, next meets 71st-ranked Viktor Troicki of Serbia.

"I have to improve for the next round," he said. "I have a tough opponent, Troicki. He is a good server."

Vamos Rafa!!!
