World number one Rafael Nadal was sent tumbling out of the Australian Open in the quarter-finals by an inspired Dominic Thiem.
The fifth seed overcame nerves to win 7-6 (3) 7-6 (4) 4-6 7-6 (6) and set up a clash with Alexander Zverev, who reached his first slam semi-final by beating Stan Wawrinka in four sets.
Wimbledon champion Simona Halep raced through to the last four, beating Anett Kontaveit in less than an hour, and there she will face a resurgent Garbine Muguruza, who defeated Anastasia Pavlyuchenkova.
