“I’m super, super sorry to disappoint you,” Sinner told the fans at the trophy presentation.

Jannik Sinner pulled out of the U.S. Open mixed doubles tournament shortly before it began on Tuesday, a day after he quit in the first set of the Cincinnati Open final because he was feeling ill.

The reimagined mixed doubles competition, a two-day event featuring 16 teams, began on Tuesday but the official draw and order of play no longer featured the Sinner-Siniakova entry.
