Venue: Center Court, Khalifa International Tennis and Squash Complex
The Doha quarterfinals are set, and both World No. 1 Alcaraz and No. 2 Sinner have cruised through without dropping a set. Here’s what to expect from Thursday’s headline matches.
Carlos Alcaraz vs Karen Khachanov
Time: 7:30 PM local (11:30 AM ET) H2H: Alcaraz leads 5-0
The Matchup
Alcaraz is riding a perfect start to 2026 after winning the Australian Open to complete the Career Grand Slam. He’s on a 27-match winning streak on outdoor hard courts. In Doha, he’s looked sharp through two matches, though he had to rally from 5-2 down in the second set against Valentin Royer.
Khachanov is the 2024 Doha champion, but he’s struggled in 2026 with a 5-3 record and early losses in Hong Kong, Melbourne, and Rotterdam. More importantly, this is a nightmare matchup for the Russian.
The H2H Problem
Khachanov is 0-5 lifetime against Alcaraz and 1-11 in sets. He’s never even forced a tiebreaker across those 11 set losses. The Russian finally won a set in their last meeting at Rome 2025, but that’s been his only moment of success in the entire series.
Khachanov needs his serve firing (he’s averaging 7 aces per match) and has to keep points short. If he gets dragged into extended baseline exchanges, Alcaraz will dominate. The Spaniard’s speed, shot-making, and ability to elevate in big moments make him especially dangerous in best-of-three.
The mental block is real for Khachanov. Even when he’s played well, he hasn’t found a way to close.
Prediction
Alcaraz to win in straight sets, looking at the H2H and Alcaraz’s current form.
Jakub Mensik vs Jannik Sinner
Time: 10:00 PM local (2:00 PM ET) H2H: First meeting
The Matchup
Mensik is having a breakthrough 2026 with a 10-2 record, an Auckland title, and an Australian Open fourth-round run before withdrawing with an abdominal injury. At just 20 years old and ranked No. 16 (career-high), he’s one of the most dangerous young talents on tour. His serve and forehand are elite-level weapons.
Sinner is 7-1 in 2026 and making his Doha debut after his Australian Open semifinal loss to Djokovic. He hasn’t faced a single break point through two matches and is winning 82% of first-serve points. He’s on a 50-match winning streak against players ranked outside the top 50 on hard courts.
This is a first-time meeting, and it’s the kind of clash that could define Mensik’s trajectory. The Czech will need to serve huge and attack off the forehand to keep points on his racquet. His weakness: defensive skills are still developing, and his forehand can break down under sustained pressure. That’s what Sinner does best.
Mensik withdrew from the Australian Open with an abdominal issue. He looked fine against Zhang in R2, but if there’s any lingering discomfort, Sinner’s game will surely expose it.
Prediction for Mensik vs Sinner
Sinner will edge this one and progress to the semi’s but I will gamble a bit and say Mensik will steal one set, possibly the first one. He has that quality and we’ve seen Sinner drop the level in periods during games before. The over 19.5 games at 1.80 (-125) is also a value bet.
