Chuang, ranked 305 in the Women's Tennis Association rankings, went down to a supremely confident Melanie South of Great Britain 1-6, 4-6.
Melanie South always looked a winner from the start in her quarter final against Chuang (the number 1 seed). Her positive approach and sharp focus was the feature of her win over the off-form Chuang.
Though South swept the opening set, Chuang broke the Briton in the first game of the second set to raise visions of a close contest. But South broke back at love in dramatic fashion in the sixth game of the second set before earning another crucial break in the 10th with a brilliant backhand return that took her to match-point and sealed the win as Chuang sent a shot long.
