The world number four Indian had to toil hard before prevailing over two-time All England champion Tine 21-13 21-23 21-13 in a women singles quarterfinal match which lasted a little less than an hour.

The 21-year-old Saina kept the pressure on her rival and played a lot of smashes though she gained more points with her dribbling at the net.

In the first game, Saina opened up a narrow lead after 5-5 but Tine kept breathing down her neck at 9-10 before the Indian started reeling off straight points to widen the gap and then take a 1-0 lead.

Not ready to lie low, Tine raced to a three-point lead in the second game but a straight six point helped Saina to zoom past her and take 14-10 lead.

However, the Dane was not someone to let it go so easily as she caught up with the Indian at 15-15 and held on to the fight by winning the second game and draw level.

In the decider, Tine again managed to open up a narrow two-point lead early but Saina soon gathered herself and changed the calculation by leading 9-7 and kept the pressure intact as Tine's game crumbled.
