World No. 1 Jannik Sinner made quick work of his Round of 16 opponent, Alexander Bublik, to book a spot in the U.S. Open quarterfinal Monday night. The Italian was likely ready to call it a night when he became victim to a tennis fan standing courtside who tried to steal something out of his bag.
After Sinner's dominant straight-sets victory over Bublik at Arthur Ashe stadium, he walked over to give his towel to a fan, which was considered a pretty typical post-match interaction. While his back was turned, however, another fan was caught on camera unzipping Sinner's tennis bag and trying to take something.
