Daniil Medvedev of Russia argues with the chair umpire during his Men's Singles third round match against Feliciano Lopez of Spain on day five of the 2019 US Open at the USTA Billie Jean King National Tennis Center on Aug. 30, in Queens(CNN) - Daniil Medvedev has become this year's US Open villain.
When learning of the violation that chair umpire Damien Dumusois had given him, Medvedev threw his racquet.
After he won, surrounded by boos, Medvedev raised up his arms, motioning to the crowd to keep going.
"Thank you all, guys, because your energy tonight gave me the win," Medvedev said in an interview on court.
In 2017 at Wimbledon, he was fined $14,500 for several infractions, including tossing coins in the direction of chair umpire Mariana Alves after a five-set loss.
