Huber and Muray have bettered their French Open quarter-final showing
Jamie Murray and Liezel Huber continued their mixed doubles run as they reached the semi-finals by beating second seeds Daniel Nestor and Chia-Jung Chuang.
Murray and Huber raced into a 5-1 lead in the first set and although they were pegged back, took it 6-4.
They fell 4-2 behind in the second set but, with Judy Murray among the crowd, hit back to win five of the last six games to take it 7-5.
They beat sixth seeds Julian Knowle and Yung-Jan Chan 6-4 6-3 in round three.
Huber and defending champion Murray, who won the 2007 title with Serbia's Jelena Jankovic, are seeded 12th.
The 22-year-old Murray, sporting a new short haircut this week, lost out in the men's double with partner Max Mirnyi on Monday.
Murray was on court at the same time as Andy was being beaten by Rafael Nadal in the singles quarter-finals on Centre Court.
