Ace Indian shuttler Saina Nehwal was on course for her third consecutive Swiss Open title as she stormed into the semifinals of the Grand Prix Gold tournament after thrashing Tzu Ying Tai of Chinese Taipei here.

The top-seeded Indian outplayed her sixth-seeded opponent 21-11, 21-12 in the quarterfinal match that lasted just 29 minutes.

Saina now plays fourth seed Shixian Wang of China in the semifinals, whom she had beaten in the final last year and against whom she had a career head-to-head record of 4-1 with the Indian having won the last four encounters between them.
