World Championship Wrestling pay-per-view event
The 1990 Great American Bash was the second annual Great American Bash professional wrestling pay-per-view (PPV) event produced by World Championship Wrestling (WCW) under the National Wrestling Alliance (NWA) banner, and the sixth annual Great American Bash event overall. It was the final held under the NWA banner, as WCW seceded from the NWA in January 1991. The event took place on July 7, 1990, at the Baltimore Arena in Baltimore, Maryland. This was the third Great American Bash held at this venue after the 1988 and 1989 events. The 1990 event featured the WCW debut of Big Van Vader.
In the main event, Ric Flair defended the NWA World Heavyweight Championship against Sting. Sting pinned Flair after countering his Figure Four Leglock attempt into a small package. During the match, The Steiner Brothers, Paul Orndorff, and The Junkyard Dog (the "Dudes with Attitudes") surrounded the ring to prevent outside interference by The Four Horsemen. During the entirety of the match, Ole Anderson was handcuffed to El Gigante.
