Federer wins on return to Rotterdam
Roger Federer did not disappoint in his first appearance in Rotterdam for seven years as he safely moved into the second round.
The Swiss legend broke Frenchman Nicolas Mahut once in each set to secure his passage into round two thanks to a 6-4 6-4 win.
Federer, who is playing in the Dutch event for the first time since winning it in 2005, goes straight through to a quarter-final to play Finland's Jarkko Nieminen because his scheduled second round opponent Mikhail Youznhy has been forced out of the tournament with an injury.
"Any win is a good win. Frankly I'm glad to be in the quarter-finals," said Federer.
"It's always tough to make the change from clay (where he was playing Davis Cup) but after losing my last two singles matches a win is great.
"I had to get used to the conditions quickly. It was a good start, I came through well, Nicolas is a tough player."
World number three Federer is the top seed in Rotterdam. Second seed Tomas Berdych and third seed Juan Martin del Potro also progressed on Wednesday.
Del Potro needed three sets to defeat Michael Llodra 6-4 6-7(3) 6-4 but Berdych stormed past Lukas Rosol 6-4 6-2.
Berdych then progressed further as Marcos Baghdatis was forced to retire at 3-0 down in the opening set of their match.
