Novak Djokovic Curses at Heckling Fan During Match at Monte Carlo

World No. 1 Novak Djokovic lost to Casper Ruud in his semifinals match at Monte Carlo on Saturday in three sets, and the frustrations on the court were high.

There were some tennis fans in the crowd who heckled Djokovic throughout this high intensity match, and the 24-time Grand Slam champion reached his breaking point when he was down 3–4 in the third set.

After Djokovic hit a shot out, a fan shouted and triggered the Serbian. Djokovic yelled back at the fan with a NSFW response: "Shut the f--- up!" He kept shouting at the fan, but it is unclear what he said as the chair umpire was speaking over him.

This definitely wasn't the first time Djokovic has shouted at a fan to be quiet during a match- and it surely won't be the last.

Djokovic lost 4–6, 6–1, 4–6 to Ruud. The Norwegian went on to lose in the Monte Carlo finals on Sunday to Greek Stefanos Tsitsipas in two sets.
