The scheduling of the Cincinnati Open final on Monday has caused chaos ahead of the start of the new-look US Open mixed doubles event

The No. 1-ranked Sinner, the defending champion in singles at Flushing Meadows, was supposed to compete in mixed doubles with Katerina Siniakova.

He will be desperate to retain his crown but will need to be in top condition in order to stand the best chance of success.

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.

Jannik Sinner’s recovery from physical and psychological stress was outlined, easing doubts over his US Open participation after the Cincinnati setback.
