The incident occurred during the second set with the score 2: 1 in favor of Djokovic at Medvedev's serve.

The Russian delivered an irresistible blow to the corner of the court, after which the Serb hit the court several times with a racket and broke it.

After that, Djokovic received a warning from the judge.

The match between Medvedev and Djokovic takes place at the Arthur Ash Stadium in New York.

For the Russian, this is the second career finals at the US Open.

The Serb is a 20-time champion of the Grand Slam tournaments and, if he wins, will become the owner of the calendar Grand Slam. 

Earlier it was reported that Djokovic lost the starting set in the fifth match in a row.
