LONDON: British teenager Jack Draper continued his impressive run at the Queen's Club championships as he beat Kazakhstan's Alexander Bublik 7-6(5) 7-6(0) on Wednesday.
Draper, who knocked out Italian world number 19 Jannik Sinner in his opening match, used his powerful forehand to great effect against the tricky Bublik.
The 19-year-old did wobble when he served for the match at 5-4 in the second set and was broken after a string of errors. He then saved a set point to force a tiebreak he won with ease.
Wildcard Draper is Britain's youngest ATP quarter-finalist since Andy Murray in 2006.
In it he will face British number two Cameron Norrie who continued his impressive season by beating Russian fifth seed Aslan Karatsev 7-5 6-2.
"To be a quarter-finalist at Queen's sounds amazing," Draper, runner-up in the Wimbledon junior event in 2018, said.
"I thought I blew it near the end but I'm glad I stuck with it. The crowd helped me get over the line."
Two-time Wimbledon champion Murray, making his return to grasscourts singles action for the first time in three years, faces Italian Matteo Berrettini on Thursday.
