Toronto - Two-time champion Roger Federer has reached the Rogers Cup quarter-finals by beating Michael Llodra of France 7-6 (2), 6-3 on Thursday.
Federer, who won here in 2004 and 2006, lost his serve once in each set but could rely on a much better second serve.
The third-seeded Federer will next play seventh-seeded Tomas Berdych of the Czech Republic, who edged Alexandr Dolgopolov of Ukraine 6-3, 6-7 (5), 6-4 without losing his serve.
David Nalbandian of Argentina accounted for fifth-seeded Robin Soderling of Sweden again in extending his winning streak to 11 matches.
Nalbandian won the third-round match 4-6, 6-4, 6-1 for his sixth win over Soderling in seven clashes.
Nalbandian withstood 14 aces and served eight double faults. He won his 11th career title in Washington last weekend.
In later matches, Andy Murray takes on Gael Monfils of France, and top-seeded Rafael Nadal faces Kevin Anderson of South Africa.
