American fourth seed Andy Roddick [ Images ] and fifth seeded Gael Monfils of France [ Images ] reached the second round of the Qatar Open with easy wins in Doha on Monday.

Roddick beat Spaniard Ivan Navarro 6-1, 6-3 in a little over an hour while Monfils outplayed Czech Republic's Jan Hernych in a 6-2, 6-2 victory.

"I didn't do anything stupid," said Roddick. "I was pretty happy with the way I played."

Monfils, who lost to Roger Federer [ Images ] in the 2006 final in Doha, was too good for Hernych.

The Frenchman won the first set in quick time, breaking his opponent in the fourth and eighth games, and took a 5-1 lead in the second before seeing off a short-lived fightback from Hernych and clinching the win in 55 minutes.

"It was a good match to start the season," said Monfils. "If I win one more match, then I should run into Rafa [Nadal].

"I have been practising hard and did everything perfectly today."

The tournament's top three seeds -- Nadal, Federer and Andy Murray [ Images ] -- were not in action on Monday.
