Wimbledon champion Roger Federer eased into second round by taking just 46 minutes to beat Tomas Behrend 6-1, 6-1 on the Swiss Open held in Gstaad on Tuesday.

Federer successfully defended his title on Wimbledon with victory over American Andy Roddick. After arriving in the Alpine resort late on Monday, the Swiss world number one comfortably moved into the second round of the tournament, where he finished runner-up last year.

Federer, who has won six titles this season, outclassed the Brazilian-born German Behrend, who won just two games and was broken four times against the tournament's top seed.

Federer had earlier received a standing ovation and was presented with a traditional, three-metre-long, Swiss alphorn as reward for his Wimbledon victory.

In other matches on Tuesday, second seed Juan Carlos Ferrero was upset by Austria's Stefan Koubek 7-6, 6-4, while fifth seed Andrei Pavel of Romania was beaten by Switzerland's Davis Cup captain Marc Rosset 7-6, 6-4.

Rosset, the 1992 Olympic champion who is contemplating retirement, said the match had taken a toll on his 33-year-old body.

Ferrero's compatriot David Ferrer progressed into the second round with a 2-6, 6-3, 6-4 victory over Tomas Berdych.

Third-seed Rainer Schuettler also progressed with a 6-4, 1-6, 6-3 victory over Michel Kratochvil, fellow German Florian Mayer was a 7-5, 6-3 winner over Spaniard Albert Portas, while Spain's Felix Mantilla beat Belgium's Christophe Rochus 3-6, 6-2, 6-4.

In the final match of the day, which was briefly delayed due to bad light, Croatian Ivo Karlovic beat Spaniard Oscar Hernandez 6-3, 6-7, 6-3 in a little more than two hours.
