Paris, November 4:

Top-seeded Andy Roddick fired 16 aces in beating Dominik Hrbaty of Slovakia 6-1, 6-2 in 50 minutes to reach the Paris Masters quarter-finals on Tlursday.

Also, third-seeded Nikolay Davydenko defeated Russian countryman Dmitry Tursunov 3-6, 6-2, 6-3 with a sore right shoulder, and No 6 Ivan Ljubicic advanced his title hopes and Masters Cup ambition at the expense of No 9 Thomas Johansson, 6-3, 7-6.

Beside Johansson, former world No 1 Juan Carlos Ferrero’s bid to play in a fourth Masters Cup also ended when he lost to unseeded Czech Tomas Berdych 7-5, 6-7, 6-4.

Davydenko, still in the running for a Masters Cup berth, twice needed a massage for his shoulder, but said it was weariness rather than a serious injury.

In the quarter-finals, he’ll play eighth-seeded Radek Stepaneo of the Czech Republic, who knocked out the last Frenchman in the draw, Paul-Henri Mathieu, 7-5, 6-4.

Tommy Robredo of Spain downed 18-year-old Novak Djokovic of Serbia-Montenegro 6-4, 6-3 to move into the last eight against Ljubicic, who has a 3-0 record against the Spaniard.

Spain’s David Ferrer beat Germany’s Tommy Haas 6-2, 6-7, 6-3, and set up a match with Roddick.
