It was a terrific day for the Au family at the Asian Squash Championships in Kuwait on Tuesday as Leo Au Chun-ming upset the form book to win the men's title and older sister Annie bag silver in the women's final. Fourth seed Leo stunned the partisan home crowd by outplaying home hero and Incheon Asian Games gold medallist Abdullah al-Mezayen in three games (11-7, 11-9, 13-11). “I don’t know what to say,” said Au, 25. “I am so happy. I didn’t imagine I could win this tournament. “I performed really well in this tournament. This time I concentrated more than I normally do.” Big sis Annie Wing-chi, 26, relinquished the title she won in 2013 to world number one Nicol David, but there was no shame in that as the Malaysian has been virtually invincible for the best part of a decade - this was her ninth Asian women's championship title. Au, who won the title in David's absence last time, went down 12-10, 11-7, 11-8. Third-seeded Au earlier beat Iranian Sogol Samoodi and Malaysian Rachel Arnold in her first two matches, before surviving a five-game thriller against another Malaysian, Delia Arnold, in the semi-finals. David eliminated two other Hong Kong players, Vanessa Chu and Liu Tsz-ling in the second round and quarter-finals, before knocking out Joshna Chinappa from India in the semi-finals. David won the tournament eight times in a row, but was absent at the last event before returning for the latest championships.
