On July 5, 1992, Armstrong won the WCW Light Heavyweight Championship (also known as the second incarnation of the NWA World Junior Heavyweight Championship and the first incarnation of the WCW Cruiserweight Championship), by defeating Scotty Flamingo. He soon injured his knee during a tour of Japan in a match against The Great Muta in Sapporo, and was stripped of the title at the Clash of the Champions XX two months later. He returned weeks later, and remained with the company until early 1995.
