The young Majerle continued to be used as a backup for the next two seasons, and became popular for his impressive jumping ability and "thunderous" slam dunk that would lead to his nickname "Thunder Dan". During the 1989–90 season, he started in 23 games and increased his scoring average to 11 points a game as the Suns again advanced to the Western Conference Finals where this time they were eliminated by the Portland Trail Blazers. Despite another successful season for Majerle and the Suns in the 1990–91 season, they fell in the first round of the playoffs to the Utah Jazz. Majerle had become an effective three-point shooter and defensive specialist, and was named to the 1990–91 NBA All-Defensive Second team at the conclusion of the season.
