Montreal’s Félix Auger-Aliassime advanced to the quarter-finals of the Qatar Open tennis tournament Wednesday when second-round opponent Hamad Medjedovic withdrew with a right leg injury.
Auger-Aliassime will next face Russia’s Daniil Medvedev on Thursday.
Medjedovic had advanced with a 7-6 (6), 5-7, 7-6 (5) upset of sixth seed Stefanos Tsitsipas in first-round action Tuesday. The Serbian was in clear discomfort as he fought through the third-set tiebreak.
Auger-Aliassime also needed a third-set tiebreak in his first-round match, a 4-6, 6-4, 7-6 (2) win over French qualifier Quentin Halys.
Medvedev, ranked sixth on the ATP Tour, holds a commanding 7-1 head-to-head record versus Auger-Aliassime, but the Canadian won the most recent meeting in the round of 16 at the 2024 Paris Olympics. The Russian defeated Auger-Aliassime in the Qatar Open semi-finals in 2023.
Auger-Aliassime, tanked 23rd in the world, is seeking his third ATP Tour title of the season.
