US Open 2025 live updates: Semifinals latest with Djokovic, Alcaraz and Sinner in action today

If there’s a challenger to prevent Jannik Sinner from repeating as U.S. Open champion, it’s Carlos Alcaraz. The 22-year-old Spaniard remains a threat on the hard courts, having won the U.S. Open in 2022.

During that tournament, Alcaraz outlasted Sinner in the quarterfinal, a five-set thriller that ended past 2 a.m. ET in the morning. The power and exquisite movement make Alcaraz a contender at Flushing Meadows.

The key for him will be maintaining that consistency. He has shown an affinity for lulls during his matches, when the intensity isn’t there and his shots are inconsistent, leading to unforced errors.

Alcaraz beat Sinner at the French Open, saving several championship points to win an all-time classic that lasted five hours, 29 minutes. Alcaraz made his third consecutive Wimbledon final before losing to Sinner in four sets.

Should Alcaraz win here this fortnight, it would be his second U.S. Open title. He would move two ahead of Sinner with six career slam titles.
