The Qatar ExxonMobil Open witnessed a massive upset on Thursday evening in Doha. Czech teenager Jakub Mensik stunned world number two Jannik Sinner in the tournament’s quarterfinals. Mensik secured the victory with a final score of 7-6(3), 2-6, 6-3 after over two hours of play. This result represents the most significant win of the young player’s professional career to date.
Mensik entered the match as a significant underdog against the reigning Australian Open finalist. However, he showed remarkable composure by winning a tight first-set tiebreak. Sinner responded with the clinical precision that has defined his recent dominance on hard courts. The Italian took the second set convincingly to force a deciding frame in the Qatari capital.
The final set saw Mensik regain his aggressive form and break Sinner’s serve early. He utilized his powerful serve and heavy groundstrokes to keep the world number two on the defensive. Sinner struggled to find his rhythm during the critical closing games of the match. Mensik eventually closed out the contest to secure his place in the final four.
This loss is a significant blow for Sinner, who had been on a dominant run. It marks the first time in over a year that he has failed to reach consecutive finals. The Italian praised his opponent’s level of play following the conclusion of the match. Sinner will now look to regroup before the upcoming Masters 1000 events in the United States.
For Mensik, the victory validates his status as one of the tour’s fastest-rising talents. He has now reached his second semifinal of the 2026 season following a win in Auckland. His performance in Doha has guaranteed a significant rise in his ATP ranking next week. The Czech player is quickly becoming a dangerous opponent for the world’s top-ranked athletes.
Mensik will now face Frenchman Arthur Fils for a spot in the championship match. Fils advanced earlier in the day with a straight-sets victory over his opponent. This upcoming semifinal features two of the most promising young players currently on the ATP Tour. Fans in Doha are eager to see if Mensik can maintain his giant-killing form.
The other half of the draw features top seed Carlos Alcaraz against defending champion Andrey Rublev. Alcaraz survived a difficult three-set battle against Karen Khachanov to reach the semifinals. The potential for a final between Alcaraz and Mensik is now a major talking point. Tournament organizers are delighted with the high level of competition during this year’s event.
