Australian fifth seed Samantha Stosur has fallen to world No.10 Angelique Kerber in the semi-finals of the Hong Kong Open.
The second-seeded German easily accounted for Stosur on Saturday with an easy 6-2 6-2 victory.
Kerber saved seven of eight break points during a one-sided match, with the Australian managing only a 57 per cent first-serve rate and winning just 44 per cent of points from her first serve.
Up until the semi-finals, Stosur had performed strongly in Hong Kong, after suffering early exits in Tokyo, Wuhan and Beijing.
Former world No.1s Venus Williams and Jelena Jankovic will face off in the other last-four encounter for a place in the final, with Kerber awaiting the winner.
