"I’m just happy that I was fighting," King said.

"I have been facing some tough opponents, who have been playing well and even when I’m down and out I have been able to fight back, so I think regardless of my squash at the moment I think just having the hunger and desire back in my belly is the thing I take away each night and I’m most happy with."

Hania El Hammamy of Egypt, the 14th seed, is also through after she defeated Sivasangari Subramaniam of Malaysia 11-8, 10-12, 11-8, 11-9.
