DiSalvo also helped Don Muraco win the Stampede North American Title from Mahkan Singh.
DiSalvo moved on to the World Wrestling Council (WWC) promotion in Puerto Rico in 1989, where he again was known as "Sadistic" Steve Strong but this time with a satanic gimmick.
The feud ended when DiSalvo lost against Colon in a Retirement match for the WWC Universal Heavyweight Championship on November 23, 1989.
The following month, he competed on a joint house show tour with the WWF and Arena Wrestling Alliance, tagging with Mano Yanez on three events against The Pitbulls.
DiSalvo made his first televised appearance on the January 5, 1991 episode of WCW Saturday Night, defeating Man Mountain Bailey.
