Defending champion Nour El Sherbini avenged her U.S. Open quarter-final defeat to eventual winner Nour El Tayeb as she moved into the last four in Brooklyn to continue the defence of her Carol Weymuller Open title.
The World No.1 went down by three games to one against fellow Egyptian El Tayeb in Philadelphia but this time the scoreline went in El Sherbini’s favour, with her tie-break victory in game three proving crucial as she completed an 11-9, 4-11, 14-12, 11-6 victory.
“I’m feeling good, it was one of my hardest matches,” said El Sherbini.
“There were a lot of long, hard rallies and it was tough, I’m so happy to be through. It’s another Egyptian and I’ve been training with both of them for the last 11 years.”
El Sherbini’s semi-final opponent will be compatriot Salma Hany Ibrahim, the World No.19, who followed up an impressive first round victory over India’s World No.13 Joshna Chinappa with a quarter-final win against qualifier Mariam Metwally.
In the other semi-final, World No.3 Raneem El Welily and World No.10 Joelle King will lock horns for the second tournament in succession after they clashed in last week’s U.S. Open semis.
El Welily, who got the better of King in Philadelphia, defeated England’s Victoria Lust in straight games, while King overcame Hong Kong’s number four seed Annie Au by the same margin.
“I think I was a little bit flat today, so I’m kind of happy how I pushed myself to win in three,” El Welily said.
“In the third game, up until 10-7, I was going too short, too quick and wasn’t doing my best. So I thought I’ll dig in and try to do better in the hopes that it would pay off in the fourth but luckily it paid off in the third.
“Tomorrow, I’m up against Joelle again, who is playing really well, so hopefully it’ll be another good match.”
