(Reuters) - The Miami Open lost two of its biggest drawcards on Saturday with world number one Naomi Osaka suffering a shock third-round loss to Taiwan's Hsieh Su-wei after eight-times champion Serena Williams withdrew due to a knee injury.

The 33-year-old Hsieh came from a set down to prevail 4-6 7-6(4) 6-3 as her unorthodox style frustrated, perplexed and finally wore down U.S. and Australian Open champion Osaka.
