Nick Kyrgios has caused another upset to Tomas Berdych by beating the Czech for the second time in six days.
The controversial Australian tennis star sealed a 6-4 6-4 victory over the world number seven to reach the semi-finals of the Dubai Duty Free Tennis Championships on Thursday.
Last week the 20-year-old overcame Berdych in straight sets in Marseille, and eventually claimed the title - the first of his career.
During today's quarter-final in Dubai Kyrgios required treatment on his back, but he managed to come through and win the match having broken just twice.
