Squash: New Zealand's Joelle King powers into quarter-finals of Black Ball Open in Cairo

Kiwi squash player Joelle King has powered into the quarter-finals of the Black Ball Open in Cairo, beating Egypt's Nadine Shahin in straight games.

World No.8 King cast a focused figure on Tuesday (NZ time), winning 11-5, 11-9, 11-3, turning around the result from the last time the two played.

"It was by no means easy," said King, who won in just 28 minutes. 

"I actually lost to Nadine the last time we played 3-0 last year in March, so I had that in the back of my mind. I know that I'm a different player to what I was in March. It was far from easy, mentally I had to keep my focus the whole time. As we saw the other day she never gives up until the last point is over.

King's quarter-final will be against either India's Joshna Chinappa or Egyptian fourth seed Hania El Hammamy.
