Doha’s quarter-final day had everything: one major upset, two tight finishes, and the defending champion still rolling without dropping a set.
With the last four confirmed, Friday’s line-up mixes star power, title-defence momentum, and two players who have pushed their ceilings all week.
Quarter-finals: results with context
Andrey Rublev beat Stefanos Tsitsipas 6-3, 7-6(2) to stay perfect in his title defence, with Tennis Majors noting he hasn’t dropped a set and has extended his Doha winning streak.
Carlos Alcaraz came through his toughest test of the week, rallying past Karen Khachanov 6-7(3), 6-4, 6-3 to reach his first Doha semi-final and extend his 2026 run to 10 straight wins, per Tennis Majors.
Jiri Lehecka beat Arthur Fils 6-3, 6-3 (score from your match list).
Headline upset: Jakub Mensik edged Jannik Sinner 7-6(3), 2-6, 6-3, flipping the bottom half of the draw.
Storylines: what stood out
Mensik taking out Sinner is the result that reshapes the tournament, especially after Sinner’s composed run into the QFs earlier in the week.
Alcaraz showed his best problem-solving again after losing the opening set, then breaking early in both the second and third, as reported by Tennis Majors.
Rublev keeps moving like a defending champ should: efficient, calm, and still unbeaten in sets in Doha.
Friday semi-finals (times)
Friday’s semi-finals are set: Alcaraz vs Rublev at 17:30.
Then Arthur Fils meets Jakub Mensik at 19:00, a true “next-gen” semi with a final on the line.
