JACK DRAPER celebrated his elevation to British number one today by beating defending champion Frances Tiafoe to reach the semi-finals of the Stuttgart Open.

Draper’s run in Germany coupled with Cameron Norrie’s shock loss to Jack Pinnington Jones in Nottingham means the 22-year-old will top the domestic standings for the first time on Monday.

He will also hit a new career high in the low 30s, potentially enough to earn him a seeding at Wimbledon, after battling to a 5-7 6-4 7-6 (1) victory over American Tiafoe.
