Top Indian shuttler Saina Nehwal has entered the women's singles quarterfinal of the Denmark Open Super Series Premier. Saina lastnight defeated her old rival Minatsu Mitani of Japan 21-12, 21-10 at the Odense Park. Now, the Olympic bronze medallist will fight against Chinese second seed Shixian Wang for a place in the semifinals. Saina has a reason to be delighted as she has a 5-3 lead in head-to-head over the Chinese, whom she beat the last time they played at the Australian Open in June. Earlier, Indian shuttler P.V. Sindhu progressed to the quarter-finals in Odense yesterday. Two-time World Championship bronze medallist Sindhu defeated Russia's Ksenia Polikarpova 21-17, 21-19 in their first ever match.
