Video - Shanghai 2013: The Strangest Sequence of Djokovic's Career

The Serbian surprised spectators during the 2013 Shanghai Masters 1000. Without any real explanation, he found himself unable to control his movements during the final against Juan Martin Del Potro.

This sequence continues to circulate around the tennis world even twelve years later. While Djokovic and his exploits are of course rewatched daily by many fans, the 2013 Shanghai final stood out for a completely different reason.

Having dropped to world No. 2, Djokovic challenged Juan Martin Del Potro in the final. After easily winning the first set 6-1, he began to gradually lose control of the match.

As if his body was suddenly possessed, the Serbian produced a series of surreal shots before finally regaining his composure and winning 6-1, 3-6, 7-6.

Last year, the man himself responded to Tennis Legend media, humorously explaining that he had "lost his balance."
