Pavlyuchenkova stuns Bertens; Stephens loses

Osaka - Pavlyuchenkova set up a quarterfinal date with in-form Japanese wildcard Misaki Doi

Russia's Anastasia Pavlyuchenkova stunned second seed Kiki Bertens 6-1 7-5 to reach the Pan Pacific Open quarterfinals in Osaka on Thursday, while American Sloane Stephens suffered another early exit.
Pavlyuchenkova set up a quarterfinal date with in-form Japanese wildcard Misaki Doi. Third seed Stephens, who has not reached a quarterfinal since the French Open in May, was outplayed in a 6-0 6-3 defeat by Italian Camila Giorgi.
Despite landing just 38% of her first serves in the match, unseeded Giorgi made her opportunities count when she got into play and went on to win the first eight games.
The Italian number one finished with 23 winners to 21 unforced errors to book her third quarterfinal appearance in her last six events, where she will face Belgian Elise Mertens.
