Juan Manuel Cerundolo, the man who beat the man at the French Open, has backed up his incredible triumph over Jannik Sinner with another record-breaking victory.
On another day for the marathon men to show off their steeliness in steamy Paris, Argentine Cerundolo, who thrived as the icy world No.1 Sinner melted in the heat two days earlier, outdid himself by chalking up another monumental five-set victory in two minutes under six hours.
In the longest French Open match for six years -- effectively two-and-a-half hours longer than it took him to down Sinner -- the world No.56 beat young Spanish star Martin Landaluce 6-4 6-7 (7-9) 7-6 (7-4) 6-7 (4-7) 7-6 [10-8].
The good news for the presumably exhausted Cerundolo was that his last-16 opponent will be feeling just as weary, after Italian Matteo Berrettini required five hours 13 minutes to defeat another seemingly indestructible Argentine Francisco Comesana 7-6 (7-3) 5-7 6-7 (4-7) 6-4 7-6 (15-13).
