Jakub Mensik secured the biggest triumph in his career after defeating world number 2 Jannik Sinner 2-1 sets in Doha and advanced to the ½ finals of the tournament in the Middle East. Mensik reached back-to-back ½ finals in Qatar, as that was his 10th consecutive victory.
The Czech player needed a tiebreak to win the 1st set as the set finished without breaks, and Jakub triumphed 7-3 points in the tiebreak.
However, Sinner bounced back in the 2nd set and won it comfortably 6-2 as the Italian had 2 break points and converted them both, while Mensik had only 1 chance to break his opponent’s serve, but Jannik saved it.
In the deciding set, Jakub was the better player, and this time, Mensik had 2 break chances and converted them both, while Sinner was left with only 1 break opportunity, but failed to convert it, and the world number 6 won 6-3 in the 3rd set and advanced to the semis in Doha.
For a place in the final, Mensik will face world number 40 Arthur Fils from France, who beat Jiri Lehecka in straight sets earlier today.
