A Seattle Seahawks fan learned the hard way not to mess with the US Open's Twitter account.
It all started with one of the cheekiest plays you'll ever see in a professional tennis match. Nick Kyrgios was facing off against Stefanos Tsitsipas in the Wimbledon men's singles third round. At some point, Kyrgios noticed that Tsitsipas was standing a little too far back when looking to receive a serve. Being the creative player that he is, Kyrgios did something unusual -- instead of a standard overhead serve, he dropped the ball, stuck his racket between his legs, and hit a soft serve that forced Tsitsipas to charge forward.
