Semifinals: Jannik Sinner vs. Felix Auger-Aliassime
Arthur Ashe Stadium — 7 p.m.
- The second of two blockbuster 2025 US Open semifinals will see defending champion Sinner take on surging Canadian Auger-Aliassime. The 25-year-old Auger-Aliassime is one of the few active players to boast a winning record against the world No. 1; he holds a slim 2-1 edge in their head-to-head, though his two wins came in 2022.
- Three weeks ago in the Cincinnati quarterfinals, Sinner scored his first win against the Canadian with an emphatic 6-0, 6-2 result. The Italian went on to reach the final at the ATP Masters 1000 event but was forced to retire due to illness after just five games against Carlos Alcaraz.
- Sinner is seeking his third major title of the season after winning the Australian Open and Wimbledon. He could have been playing for a calendar-year Grand Slam in New York, but he missed out on three match points against Alcaraz in an epic Roland Garros final.
- A four-time Grand Slam champ, Sinner has won all three hard-court majors since his maiden triumph at the 2024 Australian Open.
- Auger-Aliassime is competing in his second Slam semifinal, four years after reaching his first at the 2021 US Open. His three best major results came in succession when he reached the quarters in London and Melbourne either side of his New York run.
- Prior to his current run, the Canadian could not get beyond the second round in his past six major appearances, posting a 2-5 record.
- Auger-Aliassime's two wins against Sinner came on the clay of Madrid and the hard courts of Cincinnati in 2022. He's expecting a different version of the Italian in the semis: "He's improved a lot," Auger-Aliassime said of Sinner's rise since their last meeting. "Physicality, movement got much better, stronger physically, the serve, the forehand more precise. The backhand was always consistent, the return was always good, deep."
- Sinner has lost just one set in his advance to the semis, to Denis Shapovalov in the third round. He booked his return trip to the final four with a 6-1, 6-4, 6-2 domination of countryman Lorenzo Musetti on Wednesday night.
- Auger-Aliassime was lethal in consecutive upsets against third seed Alexander Zverev and 15th seed Andrey Rublev, which sent him into the quarters. His game dipped on Wednesday against eighth seed Alex de Minaur, but his will never wavered, as he gutted out a 4-6, 7-6(7), 7-5, 7-6(4) win. After three straight upsets, Auger-Aliassime seeks the ultimate shock against the world No. 1.
- Alcaraz or Novak Djokovic will await the winner in the US Open final, to be played Sunday at 2 p.m. The opposite semifinal has a not-before-3 p.m. start time on Friday afternoon.
