The 29-year-old has suffered a number of major wrist injuries which all required operations and hampered his progression as a professional.
Despite this, Del Porto has still rose to the world No 4 ranking but has since slipped down to eighth.
During his most recent injury, the Argentine admitted he was close to calling time on his career because he never thought he would never return to his best to challenge Roger Federer and Rafael Nadal.
Del Porto has a strong record against some of the best players in the world but he had doubts that he would ever be able to reach those heights again while on the sidelines.
“Once I was very close to retiring,” Del Porto said.
“Before the last operation, between the third and fourth one.
“I was suffering not only as a tennis player but also as a person, like any person who enters into surgery and gets an anaesthetics without knowing what can happen after.
“I suffered a lot but today I can say that not even when I was world No 4 and in the best moment of my career, I could win a silver medal in Rio and the Davis Cup.
“I don’t know if I would have managed to do it if I didn’t get hurt.
“Every time that I had a wrist injury, I was world No 4 and with the chance to fight for the No 1.
“But all things happen for a reason, I see it like this.”
