Italy’s Matteo Berrettini has advanced to his first Grand Slam semi-final, beating Frenchman Gael Monfils in a thrilling five-set encounter that went for nearly four exhausting hours.

With both players fighting fatigue and a faulty serve down the stretch, Berrettini eventually triumphed 3-6 6-3 6-2 3-6 7-6 (7-5).

Berrettini finally closed it out on his fifth match point after double-faulting away his first chance long before that.

The match that began under muggy conditions ended under the closed roof at Arthur Ashe Stadium, 3 hours, 57 minutes after it began.

The 24th-seeded Berrettini advanced to face No. 2 Rafael Nadal or No. 20 Diego Schwartzman.

Monfils was hoping to join his girlfriend Elina Svitolina in the semi-finals.
