Federer, Nadal remain on collision course

World number one Roger Federer and defending champion Rafael Nadal posted straightforward second round wins on Wednesday to remain on a collision course at the Toronto Masters.

Federer was all business a day after celebrating his 25th birthday, strolling into the third round with a tidy 6-3 6-3 win over Frenchman Sebastien Grosjean while Nadal brushed past Korean qualifier Lee Hyung-taik 6-4 6-3.

Federer and Nadal, the world's two top ranked players, have already met in five finals this year and appear headed for another showdown on Sunday.

The Spaniard and Swiss have dominated the Masters Series capturing 12 of the last 14 events, including the last two Toronto Masters.

Playing in his first event since beating Nadal to claim a fourth Wimbledon title, Federer has shown few signs of rust in his return and needed just 67 minutes to sweep past Grosjean to set up a last 16 clash with Russian Dmitry Tursunov.

Nadal's victory over Lee was not as polished as Federer's performance but the Spaniard was never under any threat from his 85th ranked Korean opponent.

Also seeing his first action since Wimbledon, Nadal has been slower to shake off the holiday cobwebs and can expect a sterner test in the third round when he takes on 13th seed Tomas Berdych of the Czech Republic.

Fourth seed Ivan Ljubicic of Croatia booked his place in the third round with a 7-6 6-4 win over Frenchman Arnaud Clement.

Fifth seed James Blake, seventh seed Tommy Robredo of Spain, Australian 11th seed Lleyton Hewitt and 16th seed Tommy Haas of Germany were all second round casualties.

Blake, the top-ranked American, was swept aside by Frenchman Richard Gasquet 6-4 6-3 while Argentine Jose Acasuso needed three sets to tame Robredo 2-6 6-3 6-4.

Hewitt was trailing Sweden's Thomas Johansson 6-3 3-2 when he was forced to retire after re-aggravating a right knee injury he sustained last week in Washington.

Chilean Fernando Gonzalez, the 15th seed, booked his place in the last 16 with an emphatic 6-2 6-1 win over former French Open champion Juan Carlos Ferrero of Spain.

Murray beats Henman

Andy Murray beat British rival Tim Henman 6-2 7-6, confirming a changing of the guard for British tennis.

It was the second time the Britons had faced each other and the 19-year-old Scot lived up to his British number one status by improving his record to 2-0 against his compatriot.
