Draper defeated Popyrin in a two-hour, three-set battle of attrition to reach the quarter-finals, 3-6, 6-2, 7-6(5)

Briton Jack Draper once viewed himself as a Ferrari with reliability issues but the world number six said on Wednesday his hard work away from the court has given him the engine to cope with the physical demands of the Grand Slams.

British number one Jack Draper survived a scare to reach the Queen's Club quarter-finals with a gritty 3-6, 6-2, 7-6 (7/5) win over Australia's Alexei Popyrin on Wednesday. Draper was rocked by the world number 21 in the first set of the second round tie at the Wimbledon warm-up event.
