Jannik Sinner and Carlos Alcaraz will enter the US Open as the heavy favorites to win. They have not only won the first three Majors but have denied other players the success since the 2024 Australian Open.

Carlos Alcaraz won the Cincinnati Open on Monday after Jannik Sinner was forced to retire due to illness. Alcaraz was already up big on Sinner, the World No. 1, when he had to retire. Sinner told the crowd that he hoped to play after feeling bad overnight, but he couldn't make it work.
