 They started the match in scintillating form, steamrollering their way through the first set to take a 1-0 lead.The second set saw Robertson and Emms change to a more attacking style that saw them put out a lead of 6-1 then 10-6.Zhang was playing nervously and a line judge called one of his shots long to which he made a protest to the umpire, who did not have the authority to overrule the call.
