MELBOURNE Japan's Kei Nishikori reached the quarter-finals of the Australian Open for the third time when he eased past Jo-Wilfried Tsonga 6-4 6-2 6-4 on Sunday.
The seventh seed hit 31 winners and sealed his place in the last eight when Tsonga, seeded ninth, made his 36th unforced error by slashing a forehand wide to end the 122-minute contest on Rod Laver Arena.
Nishikori, who was beaten on both his previous visits to the quarter-finals at Melbourne Park, will next face reigning champion Novak Djokovic or Gilles Simon.
The former U.S. Open finalist's victory avenged his defeat to Tsonga, runner up at Melbourne Park in 2008, in a five-set thriller at the French Open last year.
