ROTTERDAM, Netherlands, Feb 20 (Reuters) - Top seed Rafael Nadal of Spain registered a comfortable 6-4 6-4 victory over Russian Dmitry Tursunov in the first round of the World Indoor Tournament on Wednesday.

Spain's world number two played a solid match against the Russian hard-hitter and took the first set in 36 minutes after breaking his opponent's serve in the ninth game.

In the second set an early break proved sufficient for Nadal, who did not allow the world number 33 a single break opportunity.

"I felt very confident about this match and every aspect of my game," Nadal told reporters.

"On this surface I have to serve well to play a good tournament this week and my service today was ok but I can do five or 10 km faster."

"But it was special to play a first round (match) for more than 8,000 spectators."

Earlier, Britain's Andy Murray and Australian Lleyton Hewitt were knocked out in their first round matches.
