Daniil Medvedev had a meltdown on the court at Louis Armstrong Stadium Sunday night at the U.S. Open in his loss against Benjamin Bonzi.

Medvedev had another meltdown after the final point, returning to his chair and smashing his racket into pieces in front of a stunned crowd. His erratic behaviour led to Boris Becker urging him to seek 'professional help', with Andrey Rublev also offering his fellow Russian some words of advice.
