Jannik Sinner has been sensationally knocked out of the French Open after suffering from cramping when serving for the match during his second-round clash against Juan Manuel Cerundolo.

The world No 1 and hot favourite at Roland Garros was struggling during the third set, losing 15 points in a row before calling for a medical timeout and treatment in the middle of a game when 6-3 6-2 5-1 ahead and serving for the match.

Courtside mics also captured Sinner saying he felt dizzy and nauseous as he fell 0-40 down on serve. The Italian had moved 5-1 ahead in the third, but proceeded to lose the next six games before and after treatment to lose the set 7-5.

Into the fourth, Sinner was broken twice to fall 5-1 behind with his body continuing to ail him, losing the set 6-1, before the fifth and final set saw Cerundolo to another 6-1 success in an almighty tournament shock.
