Hong Kong: Joshna Chinappa put up a valiant fight against Alison Waters but the world number four eventually managed to tame the unseeded Indian 3-1 in the Women`s Cathay Pacific Sun Hung Kai Financial Hong Open Open, here.
Joshna went down 14-12 7-11 3-11 6-11 but not before making the second seed English opponent work hard for every point in a contest that lasted 41 minutes.
A six-time quarter-finalist since 2007, Londoner Waters earned only her second-ever semi-final berth in Hong Kong where she will renew her rivalry with top seed and World No.1 Malaysia`s Nicol David.
The 11-time Indian champion from Chennai was celebrating her first ever appearance in the last eight of a World Series event after upsetting the No.7 seed Natalie Grinham and 15th seed Line Hansen in the previous two rounds.
Egypt`s Nour El Tayeb also recorded an impressive upset when she defeated India`s in-form 14th seed Dipika Pallikal 15-13 11-6 11-2 in the WSA World Series Gold event.
"I`m happy with my performance, because I`ve been training very hard, and the hard work is paying off," said the jubilant 20-year-old from Cairo afterwards.
"Beating Dipika is very important for me, because she`s had some really great results lately, and it`s even sweeter because it`s my first time ever in Hong Kong!" In the men`s section, Saurav Ghosal went down against fourth seed Nick Matthew, the reigning and three-time World Champion from England.
Matthew fell to his lowest-scoring game since May in the opener against Indian No.1 Ghosal. But the 33-year-old World No.3 recovered to level the match, then maintained the upper hand throughout the next two games to beat the new World No.15 from Kolkata 3-11 11-5 11-4 11-8.
"Credit to @SauravGhosal tonight," tweeted Matthew later. "He played a perfect game for that court & made me play really well to win @HKsquash".
