The 39-year-old Spaniard Feliciano López traced the Italian Lorenzo Sonego (30), after winning 5-7, 3-6, 7-5, 6-3 and 6-4, so he will face the young Russian Andrey Rublev (7) in the third round of the Australian Open.
The toledano finished the game exhausted after three hours and twenty minutes of intense fighting under 32 degrees that marked the thermometer throughout the morning in Melbourne Park.
Feliciano, who disputes his Grand Slam number 75 in a row, got the ticket for what will be his third match in the ‘major’ Australian for the first time since 2016, when he fell to American John Isner.
The Spanish converted the six break balls that he had, while his rival, less successful in the delicate moments, converted only four out of ten.
His next rival will be the Russian Rublev, who is going through one of the sweetest moments of his career after winning the ATP Cup last week and overcoming his first two rounds in three sets.
