New Zealand squash number one Joelle King will face fourth-seeded Kasey Brown of Australia in the Texas Open semi-finals.
Fourth-seeded King, the defending champion, took just three games to overcome Hong Kong's Joey Chan 11-5, 11-8, 11-8 in the quarter-finals in Dallas.
Top seeded Australian Rachael Grinham defeated her younger sister Natalie to book the other semi-final spot against surprise qualifier Sarah Kippax after the Englishwoman upset Wee Wern, the world No13 from Malaysia.
