Jannik Sinner had a bizarre moment with a fan at the US Open after a spectator attempted to reach into his bag following his quarter-final win over Alexander Bublik.
Sinner demolished Bublik 6-1 6-1 6-1 under the lights on Arthur Ashe Stadium and a fan, who may have felt short-changed by the 81-minute win, appeared to try and open his bag while the World No 1 gave away his towel and posed for a photograph.
