Tennis superstar Daniil Medvedev had an unforgettable performance on the court at the Monte-Carlo Masters — and by “performance,” we mean an epic meltdown for the ages.

The Russian athlete suffered the first double bagel loss of his career against Matteo Berrettini on Wednesday … and during the blowout defeat, he took his frustrations out on his racket.

Medvedev slammed his equipment on the ground not once, not twice … but seven times in a row before throwing it in the trash in the second set.

The No. 10-ranked player in the world never seemed to find his rhythm during the match … and it ultimately only lasted 49 minutes.

While the crowd let out some cheers during the blowup, Medvedev was handed an unsportsmanlike conduct code violation … and he will undoubtedly get a fine.

This is par for the course with Medvedev — he’s known to express his emotions in real time when he’s on the court.
