World No. 1 in men's singles, Jannik Sinner, has pulled out of the US Open mixed doubles event.

The decision comes after his early retirement from the Cincinnati Open final against Carlos Alcaraz due to illness.

Sinner was set to team up with Katerina Siniakova, a top-ranked doubles player and an 11-time Grand Slam champion.

Here are further details.

Siniakova, who won a gold medal at the 2024 Paris Olympics, is yet to find a new partner after Sinner's withdrawal, as per reports.

The official draw and order of play were updated Tuesday morning but their spot was marked as "Qualifier/Qualifier."

This comes just hours before the start of the event.

Sinner was originally paired with Emma Navarro for the mixed doubles event. However, she had to withdraw from the competition to play at Monterrey Open and regain her form ahead of the US Open.

This led to Sinner's partnership with Siniakova before it could even begin.

Alcaraz pocketed the Cincinnati Open after Sinner was forced to retire after just 23 minutes into their championship-match clash.

Defending champion Sinner called for the doctor after surrendering a 0-5 lead in the opening set.

Thereafter, he was unable to continue. Alcaraz won his sixth title of the season and a 22nd tour-level trophy.

"I'm super, super sorry to disappoint you," Sinner said to the fans after he was forced to leave.
