Third-seeded Samantha Stosur beat Swiss qualifier Belinda Bencic of Switzerland 6-4, 6-2 at the Japan Open on Wednesday to reach her first quarter-finals since her title run in Carlsbad in August.
Stosur lost her serve twice but broke Bencic five times at Utsobu Park and will next face either Kimiko Date-Krumm or Misaki Doi in the last eight.
Stosur won in Osaka in 2009 and was runner-up in 2011 and a semifinalist in 2012.
