Top-seeded Rafael Nadal beats France's Gilles Simon 6-4, 6-4, 6-2 in 3rd round of US Open

Top-seeded Rafael Nadal beat Gilles Simon of France 6-4, 6-4, 6-2 in the third round of the U.S. Open on Sunday.

Nadal has won all his matches in straight sets, but this was the first time he didn't need any tiebreakers. Nadal has not had his serve broken at the Open. He will face fellow Spaniard Feliciano Lopez in the fourth round.

The 42nd-ranked Simon was hoping to catch a flight home to Europe later Sunday to see his son who was born Thursday.
