Rafael Nadal stretched his claycourt winning streak to 79 matches as he beat Russian Igor Andreev 6-4, 6-1 in the round of 16 at the Hamburg Masters Series.

The Russian, who beat the 20-year-old Spaniard in April 2005 in Valencia, was worn down by the French Open champion's relentless mobility and muscular topspins.

Federer, the world number one, followed Nadal out on court and needed just an hour to rack up a ruthless 6-2, 6-3 win over Ferrero, a former French Open champion.

Lleyton Hewitt battled past third seeded Russian Nikolay Davydenko 6-4, 2-6, 6-4 in a blistering clash to set up a quarter-final against Nicolas Almagro, who beat Jose Acasuso of Argentina 6-2, 6-3.

There were two more wins for Spaniards, giving them half the quarter-final slots in the 2.1 million euros tournament.

Twelfth seed David Ferrer beat the seventh seeded Croatian Ivan Ljubicic 6-3, 6-3 and Carlos Moya, another former French Open champion, recovered from a bad start to beat eighth seeded American James Blake 1-6, 6-3, 6-3.

Ferrer will play Federer, while Moya will take on the fourth seed Novak Djokovic of Serbia.
