Video - Sinner Surprised by Fan Intrusion at Six Kings Slam

Unusual moment in Riyadh: while Sinner was celebrating his victory, a fan entered the court and approached the Italian, who tried to understand the situation before security intervened.

Just after securing his spot in the semifinals of the Six Kings Slam by defeating Stefanos Tsitsipas (6-2, 6-3), Jannik Sinner was interrupted by a fan who made his way onto the court.

The Italian first greeted the young man before attempting to understand what he was asking. The fan was eventually intercepted by security, who took many seconds to react.

Sinner will return to the court in Riyadh tomorrow to face Novak Djokovic.
