Jamie Murray secured his place in the Wimbledon mixed doubles semi-finals after receiving a walkover.

Murray, who won the title with Jelena Jankovic in 2007, and American partner Liezel Huber were due to play Lukas Dlouhy and Iveta Benesova but the Czech pair withdrew with injury.

Murray, 23, booked his place in the quarter-finals after a 7-6, 4-6, 6-3 victory over sixth seeds Mike Bryan and Bethanie Mattek-Sands.

"My year has been really disappointing but if I do win, it would put a shine on it," said Murray.

"I haven't been playing so well the last couple of months."
