Federer, Djokovic advance, Wawrinka slump continues in Paris

The Swiss now faces Milos Raonic, who can still qualify for the Tour Finals after the Canadian fired 23 aces in his 7-5 7-6(7) win over Spain's Roberto Bautista Agut.

Federer, who has won five of his 10 finals this year, extended his current winning run to 14 matches as he kept his eye firmly on the world number one spot, which he can achieved by winning in Paris if Novak Djokovic does not reach the final.

World number one Djokovic will play Andy Murray for a semi-final spot after the Serbian beat Frenchman GaelMonfils 6-3 7-6(2) in Thursday's late match.

However, third seed Stan Wawrinka was knocked out in the third round when he lost 6-7(2) 7-5 7-6(3) against South African Kevin Anderson, suffering his fourth defeat in five matches.

The Swiss, who has already booked a place in the Tour Finals, had lost his opening matches in the three previous tournaments he had entered.

A solid performance in the second round in Paris against Austrian Dominic Thiem was followed by an erratic display against the 14th seeded Anderson, who served 18 aces.

Wawrinka saved two match points to force a tiebreak in the decider, but was unable to match Anderson, who upped his level to book a quarter-final spot against Czech Tomas Berdych.

Berdych kept his Tour Finals hopes alive with a 7-5 6-3 win over Spain's Feliciano Lopez as did sixth seed Kei Nishikori who beat Jo-Wilfried Tsonga 6-1 4-6 6-4.

The Japanese can make the season-ending event if he beats fourth seed David Ferrer in the Paris quarter finals, with the Spaniard having thrashed compatriot Fernando Verdasco 6-1 6-2.
