Roger Federer made a serene start to the defence of his ABN-AMRO World Tennis Tournament title in Rotterdam as he thrashed Grega Zemlja 6-3 6-1 to advance to the second round.
The world number two needed less than an hour to dispose of his Slovenian opponent and will next face home favourite Thiemo de Bakker.
A single break in the eighth game was sufficient for Federer to take the first set, while he broke twice in the second before closing out the contest with a love service game.
"I've been here and preparing for a few days, but matches are always different than training," stated Federer. "The ball flies a bit and you have to be prepared.
"I'll have to be careful against De Bakker. I played him in the Davis Cup (2012). The local players always get up for home matches. I'll have to approach him carefully and not underestimate him."
Easy for French duo
French duo Gilles Simon and Julien Benneteau both moved into the quarter-finals of event with little trouble.
Simon, seeded fifth, crushed Italian qualifier Matteo Viola 6-3 6-1 while Benneteau saw off Victor Hanescu of Romania 6-1 6-3.
There was also victory for compatriot Richard Gasquet, the fourth seed - and winner in Montpellier last week - winning his first round match against Viktor Troicki of Serbia 7-6 6-1.
Greek Cypriot Marcos Baghdatis reached the second round when his in-form French opponent Benoit Paire retired with the score 6-0 6-7 4-0.
Meanwhile, Italian Andreas Seppi was the latest seed to fall, the sixth-ranked player going down 6-3 6-4 to Matthias Bachinger of Germany.
