American Taylor Fritz overcame an unexpected third-set capitulation to beat Karen Khachanov and reach the semi-finals of Wimbledon for a first time.
The fifth seed had looked on course to wrap up the match in straight sets, with his big serving key to a two-set lead.
But things suddenly fell apart for Fritz in the third as he struggled to land his first serve while sending more shots beyond the baseline as Khachanov, 29, took it 6-1.
The 27-year-old then had a medical timeout to address some taping on his foot as he looked to avoid being taken to five sets for the third time in five matches at Wimbledon.
