Australian Donna Urquhart (pic) continued her giant-killing run in the Cayman Islands Open when she upset 5th seed Madeline Perry to reach the last 4 at Grand Cayman. Urquhart recovered from two games down – and saved two match balls – to overcome Perry, the new world No3, 6-11, 11-13, 11-8, 12-10, 11-9 to reach the biggest semi-final of her career. Urquhart now meets defending champion Nicol David, the world No1 from Malaysia who is looking for her 3rd successive title. The top seed beat Dutch qualifier Natalie Grinham 11-4, 8-11, 11-8, 11-4. Natalie’s older sister Rachael Grinham claimed the speediest route through to the semi-finals with an 11-7, 11-6, 11-7 win over English qualifier Sarah Kippax in 28 minutes. The 34-year-old 3rd-seeded Australian will now face another English opponent Jenny Duncalf, the No2 seed who had to come from a game down to get the better of France’s 7th seed Camille Serme 6-11, 11-6, 11-4, 11-7 in 53 minutes.
