The most outstanding moment in Fiasconaro's career came in the evening of 27 June 1973, in Milan.
The favourite was Jozef Plachý, a Slovak who had reached the 1968 final and the 1972 semi-final in the 800 m at the Olympic Games.
Plachý possessed a devastating finish.
Banner and Fiasconaro's tactics were to go out fast.
The plan nearly backfired when Plachý managed to stay with Fiasconaro for most of the race, before finally falling back over the last 150 metres.

On his return to South Africa, Fiasconaro went on 10-day partying spree.
He paid the toll for his overindulgence when he was easily beaten in the United States soon afterwards.
In trying to recapture his form, he overtrained.
A stress fracture in his foot signalled the beginning of the end of his brief meteoric career.

At the 1974 European Championships he developed problems with his Achilles tendon.
The constant injuries and pressure to compete led him to take a year-long sabbatical from athletics.

Fiasconaro's world record of 1:43.7 seconds was beaten at world level three years later, but is still the Italian record – perhaps the longest-lived Italian athletics record in any discipline.
