Hong Kong siblings Annie Au Wing-chi and Leo Au Chun-ming, 21, made it a family affair by reaching the women's and men's finals at the US$16,000 Buler Challenge Cup last night. Top seed Annie Au beat Malaysia's Delia Arnold 3-2 to qualify for today's title match at Hong Kong Sports Centre where she will come up against Australia's Donna Urquhart. Unseeded Leo, 20, continued his giant-killing run by defeating Egypt's Omar Abdel Meguid, the tournament's fourth seed, 3-1 in 53 minutes. He will face Malaysia's Kamran Khan in the final.
