Maybe he just wanted to beat the 90 degree and get in the shade, but defending U.S. Open champion Novak Djokovic wrapped up another easy victory Friday to reach the third round, beating 112th-ranked Rogerio Dutra Silva of Brazil 6-2, 6-1, 6-2.

Djokovic didn't face any break points and finished with more than twice as many winners, 29, as unforced errors, 14. He needed a little more than 90 minutes to make sure he would keep intact his record of never having lost to a player ranked outside the top 100 at a major tournament.

The second-seeded Serb has dropped a total of seven games through two matches this year at Flushing Meadows.

Dutra Silva never has reached the third round at a Grand Slam tournament.

Fourth-seeded David Ferrer pulled out a 14-12 tiebreaker to cap off a straight-sets victory over Igor Sijsling of the Netherlands in the second round of the U.S. Open.

Ferrer defeated the 78th-ranked qualifier 6-2, 6-3, 7-6 (12).

In a year in which Spain's top player, Rafael Nadal, is absent because of injury, Ferrer was still the fourth man from that country to advance to the third round, with two others — Tommy Robredo and Guillermo Garcia-López — playing their second-round matches later Friday.

Ferrer saved three set points in the third to get off the court in 2 hours, 7 minutes on an 88-degree afternoon in the Grandstand stadium.

The 30-year-old Spaniard made the third round at Flushing Meadows for the eighth straight year.
