Top seed Saina takes on 6th seed Tai Tzu Ying from Taipei in quarterfinals of Swiss Open. In 6 earlier matches, Saina leads 4-2. But in the last two matches Saina has lost. While the first one she lost in 2011, the threat comes from her loss in 2013 Malaysia Open.
Saina is defending the Swiss Open title and placed as top seed. Still her fans would feel tensed as even in England Open she lost in the semifinal when none of the better ranked reached the semis.
