William Joseph Robidoux was selected by the Milwaukee Brewers in the 6th round of the 1982 MLB June Amateur Draft out of Ware (MA) High School. Billy Jo reported to Pikeville in the rookie Appalachian League that summer, slashing .287/.389/.359 in 54 games but showing little power.
The next season at Beloit (Class A Midwest), Robidoux showed more pop, banging out 30 doubles and ten home runs in a .317/.424/.460 season.
In 1984, Robidoux played at Class A California League entry Stockton. There he had a solid season, hitting .279/.387/.384 in 401 plate appearances. It is not known for sure, but seems possible the lefty swinger missed parts of two months due to a knee injury.
