Fritz will play the winner of Novak Djokovic or German Jan-Lennard Struff. Fritz finds himself just two wins away from reaching the US Open finals for a second straight year. He finished as the 2024 runner-up behind Jannik Sinner. Sinner also remains in the tournament and will have an opportunity to qualify for the quarterfinals on Monday. This will be the sixth consecutive Grand Slam event to feature at least one American male in the quarterfinal round. That is the longest such streak since another run of six straight events from the 2002 US Open to the 2004 Australian Open, according to ESPN. The biggest stories, every morning.
