Venus Williams suffered a shock exit in the second round of the WTA Hong Kong Open on Wednesday, comprehensively beaten 7-5, 6-2 by teenager Naomi Osaka. Japan's top-ranked player reeled off eight consecutive games at one stage to power into the quarter-finals. It all seemed to be going to plan for second seed Williams when she broke the 19-year-old Osaka in the fifth game of the opening set. But then the American's first serve deserted her when serving for the set at 5-4. Two double faults and a series of fierce ground strokes from Osaka which unerringly kissed the lines enabled the world number 64 to break twice and take the set 7-5.
