Muchová and Menšík win $1m US Open mixed doubles title in late-night thriller

• Czech pair beat Bencic and Cobolli in deciding tiebreak

• Revamped event draws strong crowds at Arthur Ashe

• Singles stars dominate after doubles specialists exit

To many who came to the US Open grounds this week, the showpiece of the mixed doubles championship came Tuesday afternoon, with the returns of Serena Williams (after four years away from tennis) and Carlos Alcaraz (after four months out with a wrist injury).

To the players who remained in the field after Williams and Alcaraz exited in the quarter-finals, the real highlight was Wednesday night's final at Arthur Ashe Stadium, with its $1m in prize money on the line. Karolina Muchova and Jakub Menik made the most of the spotlight, beating Belinda Bencic and Flavio Cobolli 6-3, 1-6 (10-6) for the title.
