Currently ranked fourth in the world, Wang, who won the 2010 Asian Games gold medal in Guangzhou, survived four game points on Friday to upset word No 2 Ratchanok 24-22 21-10 in the women’s singles quarter-finals.
The resurgent Chinese dominated play with impressive cross-court shots and solid defence game and outplayed the world champion, Ratchanok, for the fifth consecutive time.
Porntip, who on Friday produced a giant-killing show to stun world no 3 Wang Yihan 21-16 18-21 21-16 in the quarter-finals, was no match for red-hot Wang Shixian in the semi-finals yesterday, losing easily 21-16 21-5 in just 31 minutes.
While Ratchanok’s hopes of booking one of the eight spots in the Super Series Finals has become slim, Porntip’s semi-final place in Shanghai means she has a good chance of earning one. The next week’s series in Hong Kong will determine who will be eligible for the Finals in Kuala Lumpur next month.
