Having established himself as a rising star, Sting was one of the few UWF alumni to be pushed in the NWA. At "Clash of the Champions I" in March 1988, Sting challenged Ric Flair for the NWA World Heavyweight Championship. The match ended in a draw after the 45-minute time limit expired and the ringside judges could not declare a winner. Sting lost to Flair in several non-televised rematches following the Clash and, later that year, battled other members of Flair's stable, the Four Horsemen. Sting teamed with Koloff at The Great American Bash in July 1988 to challenge Horsemen Tully Blanchard and Arn Anderson for the NWA World Tag Team Championship; Blanchard and Anderson retained the titles when the match ended in a 20-minute time-limit draw.
