It wouold have most likely been someone in the seventies. Foosball went from zero to sport in a couple of years. So there are bound to be lots of players that went from anonymity to top ten a number of times.
But in the modern era (say 1990 to the present), it usually took a few years to reach the top ten level. You would usually see year one, the player does OK, year 2 the player sweeps amateur and experts, years 3-4 they are competing for titles. But those players were very young, and had been playing for years before actually "touring". Players like this would be: Tony, Frederic, Tommy Adkisson, Terry Moore, Billy (sort of, he turned pro at like...14 years old, but didn't really apply himslef for a couple of years, but when he did, WOW), etc.
