Losses have been rare for Jannik Sinner in recent years. That is why when the Italian does fall short, it grabs plenty of people’s attention.
Jakub Mensik, last year’s Miami champion, upset the No. 2 player in the PIF ATP Rankings 7-6(3), 2-6, 6-3 Thursday in the Qatar ExxonMobil Open quarter-finals. This was straight off the back of a semi-final defeat to Novak Djokovic at the Australian Open.
It had been a year and a half since Sinner lost before the final at two consecutive tournaments. It last happened in 2024 at Wimbledon and at the ATP Masters 1000 event in Montreal (both quarter-finals).
Sinner is now 138-14 since the start of the 2024 season, according to the Infosys ATP Win/Loss Index, giving him an astonishing 90.8 winning percentage during that period. For context, Novak Djokovic owns the best tour-level winning percentage on record at 83.3 per cent.
Since Sinner lost in the Montreal quarter-finals in 2024, he has played 19 tournaments and made the final in 15 of them, lifting 10 trophies. His five championship-match defeats came against Carlos Alcaraz.
So while Sinner has now lost in consecutive events before the final, that speaks to his consistency in recent years. Mensik will play Arthur Fils Friday for a place in the Doha final.
