London Olympic bronze medallist Saina Nehwal scripted history by reaching the finals of the prestigious All England Badminton Championship with a straight-game victory over Sun Yu of China in the women's singles competition in Birmingham.
The World No. 3 Indian, who reached the semi-finals of the event in 2010 and 2013, defeated the unseeded Sun 21-13, 21-13 in a match that lasted for 50 minutes.
Saina is now just one step away from joining Indian legends Prakash Padukone (1980) and P Gopichand (2001) who have bagged the prestigious title in the past.
The 24-year-old will face the winner of the other semi-final between seventh seeded Tai Tzu Ying of Chinese Taipei and Spain's Carolina Marin on Sunday.
After disposing her nemesis Yihan Wang of China, third seed Saina was faced with the task of taming the towering Sun, ranked World No. 18, who had seen off the likes of Nichaon Jindapon, Li Xuerui and Ratnachok Intanon over the last three days.
The Indian had come into the match with a 1-1 record against Sun, who had defeated her during the 2013 China Open but all that didn't matter as Saina stamped her authority with her wide repertoire of stroke.
Saina, who had beaten Sun at the Australian Open in June last year, lagged 0-2 behind early on as Sun showed her intent to move to 4-1.
A couple of quick points and Sun led 6-1, but Saina soon drew her rival in long drawn battle of rallies, as she scripted her recovery to move to 8-10 before the Chinese surged ahead into the break with a slender 11-10 lead.
After the interval, Saina changed her tactics and was soon rewarded with a couple points as she stretched her lead to 16-12.
The Indian soon made it 19-13. An unforced error from Sun gave Saina the advantage of seven game points and the Hyderabadi sealed it when the Chinese hit the shuttle hard and long.
In the second game, Sun once again opened up a narrow 3-2 lead but Saina kept drawing her to the net, where she looked comfortable.
The Chinese tried different things on the court to put Saina on the backfoot. She used her powerful smashes to good use to keep her nose ahead, going into the interval at 11-9.
Saina kept playing long rallies, relying more on the errors of her opponent. She won an easy point after the break and then produced a smash down the middle to claw back at 11-11.
The Indian then moved into the lead with a smash that Sun could just manage to put into the net. Saina soon erased the deficit and moved to 15-13 when Sun hit long.
She kept the pressure on the Chinese drawing her close to the net and capitalising on her better net play. The result was Sun faltered on the forecourt, committed a number of unforced errors, hitting wide and long.
Saina continued her rampaging run to extend the gap to 18-13 and was soon standing on a healthy seven-match point advantage when Sun hit the net.
