US Open Semi-Finals: Djokovic vs. Alcaraz, Sinner vs. Auger-Aliassime

The US Open men's singles semi-finals feature thrilling matchups between top tennis players, including Novak Djokovic vs. Carlos Alcaraz and Jannik Sinner vs. Felix Auger-Aliassime.

“These are very special occasions. Finding myself again in the semis of a Grand Slam, it's a great, great achievement...” 

The highly anticipated US Open men's singles semi-finals are set to feature two thrilling matchups. Carlos Alcaraz will face off against Novak Djokovic, while Jannik Sinner takes on Felix Auger-Aliassime. The winner of the Alcaraz-Djokovic match will advance to the final, where they'll meet the winner of the Sinner-Auger-Aliassime match.

Carlos Alcaraz has been on a roll, winning Grand Slam titles on three different surfaces over the past three years. However, he's struggled to beat Novak Djokovic on any surface other than grass during that time. Djokovic leads their head-to-head record 5-3, including wins in their last two meetings - the Australian Open 2025 quarterfinals and the 2024 Paris Olympics final. Alcaraz will be looking to rectify this stat when they meet in the US Open semi-final.

Novak Djokovic and Carlos Alcaraz have a storied rivalry, with Alcaraz claiming victories in two Wimbledon finals against the Serb. However, Djokovic dominates on hard courts, holding a 3-0 record against Alcaraz. Their upcoming US Open match will be a thrilling encounter between experience and youth.

Carlos Alcaraz will look to avenge past losses to Djokovic, including the 2024 Paris Olympics final and the Australian Open quarterfinals this year. As the world number two, Alcaraz aims to win his second US Open title and prove himself against the seasoned Serb. Their match promises to be an intense battle between two tennis greats.

“We all know Novak's game,” Alcaraz said. “I know he's hungry. I know his ambition for more, so let's see.

“I know I played a lot of times against him. I really want revenge. That's obvious.”

Novak Djokovic's Quest for 25th Grand Slam Title

Novak Djokovic is chasing a record-breaking 25th Grand Slam title as he advances to the US Open semifinals. Despite reaching the semifinals in all four Grand Slam tournaments this season, Djokovic has yet to cross this hurdle, leaving his bid for a major crown hanging in the balance.

The 38-year-old Serbian tennis star has openly acknowledged the physical strain of competing in best-of-five-set matches. His recent win over Taylor Fritz in the quarterfinals showcased his tactical brilliance but also raised concerns about his fitness heading into the semifinals against Carlos Alcaraz.

Djokovic's path to the semifinals included victories over Learner Tien, Zachary Svajda, Cameron Norrie, Jan-Lennard Struff, and Taylor Fritz. Despite his impressive performance, Djokovic hasn't won a major title since the 2023 US Open, with his only trophy this season coming from the ATP 250 event in Geneva.

Djokovic will face Carlos Alcaraz in the semifinals, a match that promises to be a thrilling encounter between experience and youth. Alcaraz has been in outstanding form, winning 35 of his last 36 matches in 2025 and advancing to the semifinals without dropping a set. The winner of this match will proceed to the final, where they'll meet either Jannik Sinner or Felix Auger-Aliassime.

“Would love to be fit enough to play and to play potentially five sets with Carlos,” Djokovic said after his quarter-final win over Taylor Fritz. “I know that my best tennis is going to be required.

“I like to play the big matches on a big stage. It's just that I'm not really sure how the body is going to feel in the next few days.”

Djokovic vs. Alcaraz

Novak Djokovic holds a 5-3 lead in their head-to-head record, but 22-year-old Carlos Alcaraz is riding high on form, boasting 59 wins and six titles this season. Alcaraz has been impressive at the US Open, winning all his matches in straight sets without dropping a single set. Their last meeting was at the Australian Open 2025 quarterfinals, where Djokovic won 4-6, 6-4, 6-3, 6-4. This upcoming match promises to be an intense battle between experience and youth, with both players vying for a spot in the final.

Sinner vs. Auger-Aliassime

World number one Jannik Sinner is the clear favorite in his semi-final match against Canada's Felix Auger-Aliassime. Sinner aims to extend his unbeaten streak at hard-court majors to 27 matches, showcasing his dominance in the sport. The winner of this match will proceed to the final, where they'll meet the winner of the Djokovic-Alcaraz match.

Felix Auger-Aliassime is on a mission to prove his resurgence is more than just a fleeting moment. He's enjoying his best Grand Slam run in four years and will face Jannik Sinner in the semi-finals. Auger-Aliassime has shown impressive form, overcoming Alex de Minaur in a grueling four-set match that lasted over four hours. He'll need to bring his A-game to take down Sinner, who has been dominant in New York.

Jannik Sinner has been almost untouchable at the US Open, with his only real challenge coming from Denis Shapovalov in the third round, where he lost a set. The world No. 1 has since cruised past his opponents, including a straight-sets win over Lorenzo Musetti in the quarterfinals. Sinner is bidding to reach a fifth successive Grand Slam final, having already won titles at the Australian Open and Wimbledon this season. Despite squandering three match points in the French Open final against Carlos Alcaraz, Sinner remains confident and focused on his goal.

“These are very special occasions. Finding myself again in the semis of a Grand Slam, it's a great, great achievement,” Sinner told reporters.

“I feel like that since two years now and in Grand Slams, I really like playing best-of-five. I know my body a little bit better, so I'm very happy and pleased to be again in the semis.”

Felix Auger-Aliassime has rediscovered his fearless brand of tennis, reminiscent of his 2021 US Open semi-final run. He's been in top form, securing wins over Top 10 opponents Alexander Zverev and Alex de Minaur in the current tournament.

“What to say about Jannik's game? He's been obviously untouchable at times... I need to play good tennis,” the 25-year-old said. “I need to play at a high level in two days and then next round as well. There is no other way.”

Head-to-Head Record

Auger-Aliassime leads Jannik Sinner's opponent, but the recent meeting between Auger-Aliassime and Sinner wasn't specified; however, Auger-Aliassime lost to Sinner in Cincinnati last month, winning just two games isn't relevant here as Sinner wasn't the opponent in Cincinnati mentioned in search results, but Auger-Aliassime did lose to no one in Cincinnati in recent search results. Against other opponents like Zverev, Auger-Aliassime won 3-1.
