World number one Jannik Sinner suffered one of the biggest shocks of the French Open after Argentina’s Juan Manuel Cerundolo battled back from two sets down to claim a remarkable five set victory at Roland Garros.

Sinner looked firmly in control during the opening stages of the second round clash. The Italian dominated with powerful baseline play and quickly moved into a commanding lead after taking the first two sets 6 3 and 6 2. He then surged ahead 5 1 in the third set and stood just one game away from sealing his place in the next round.

The momentum suddenly shifted as Cerundolo refused to back down. The Argentine produced fearless tennis and capitalized on signs of physical discomfort from Sinner. Cerundolo won six straight games to steal the third set 7 5 and completely changed the direction of the contest.

Sinner struggled physically as the match continued with reports of dizziness and cramping affecting his movement. Cerundolo sensed the opportunity and raised his level even further. The Argentine overwhelmed the top seed in the final two sets winning them 6 1 and 6 1 to complete a stunning comeback victory.

The result ended Sinner’s hopes of winning his first French Open title and completing a career Grand Slam. It also snapped his impressive winning streak and opened up the men’s draw in dramatic fashion.

For Cerundolo the victory marked the biggest moment of his career. The world number 56 celebrated his first ever appearance in the third round of a Grand Slam after defeating one of the favorites for the title in unforgettable style.

The Paris crowd witnessed an extraordinary turnaround that will be remembered as one of the defining matches of the tournament.
