Berrettini makes a successful Shanghai debut!

It wasn't certain that he would line up in Shanghai.

Forced to retire after leading Arthur Fils in the 2nd round in Tokyo (7-6 ab.), Matteo Berrettini has already made his return to competition.

Registered for the Shanghai Masters 1000, he didn't miss a beat.

Facing Christopher O'Connell in the first round, the Italian colossus held his nerve to win a close match (7-6, 7-6).

Relentlessly solid in important moments, Berrettini will meet Holger Rune for a rematch of their last duel in Cincinnati (Rune won 2-6, 6-1, 6-4).
