Rublev survives scare as Chinese teen stuns Tiafoe in Hong Kong

HONG KONG: World number five Andrey Rublev survived a huge scare on Friday (Jan 5) to reach the semi-finals of the Hong Kong Open, as third seed Frances Tiafoe was stunned by a Chinese teenager.

Rublev came through 6-4, 1-6, 6-2 against 19-year-old Frenchman Arthur Fils in a rollercoaster 1hr 52min of highly entertaining tennis at Victoria Park.
