British No.4 Jack Draper booked his spot in his first ATP Masters 1000 quarterfinal on Thursday night at the National Bank Open (Rogers Cup), after opponent Gael Monfils was forced to retire midway through their match.
The 20-year-old claimed the biggest win of his career over World No.5 Stefanos Tsitsipas in the previous round on Thursday morning and was a set up against Monfils when the Frenchman limped to the net in the third game of the second set and conceded defeat.
At that point Monfils was a break up in the second set against the Brit at 2-0 – but it had been another impressive display from Draper who seized both break-point chances against the Frenchman in the first set, winning it 6-2.
Draper helped Monfils up off the court after the Frenchman fell to the ground in agony.
The Briton, ranked No.82 in the world before this tournament, will now play either seventh seed Jannik Sinner or Spaniard Pablo Carreno Busta in the last eight.
