Andy Murray, Laura Robson win mixed doubles nail-biter

Andy Murray and Laura Robson are into the quarter-finals of the Olympic mixed doubles after they won a narrow three-set contest against Lucie Hradecka and Radek Stepanek at Wimbledon.

In a close opening set, the British pair came out on top against the Czechs 7-5 thanks to a single break of serve.

With both teams dropping serve in the second, Hradecka and Stepanek edged out the tie-break 9-7 after Robson had served for the match.

Into the super-tie-break and it was the Brits who came through 10-7 to book their place in the quarter-finals, where they will meet Samantha Stosur and Lleyton Hewitt of Australia.
