No one will be getting an early glimpse at the men’s world No.1 singles player in Flushing this year, nor an 11-time Grand Slam doubles champion.
Jannik Sinner has withdrawn from the U.S. Open mixed doubles event Tuesday morning, less than 24 hours after his retirement after just five games of the Cincinnati Final against Carlos Alcaraz due to illness.
The decision doesn’t come as a surprise as the defending U.S. Open champion and his team were expected to prioritize recovery for the singles tournament that starts Sunday.

The two were one of the most interesting pairings for the newly formatted two-day event with a $1 million prize awaiting the winners.
Danielle Collins and Christian Harrison, who were added about a half hour before the 11 a.m. start, replaced them.
Collins and Harrison took advantage of the opportunity, beating Belinda Bencic and Alexander Zverev 4-0, 5-3 on Tuesday afternoon at Louis Armstrong Stadium.
