In 1985, the club won its first official title, the Copa Asociación which was played among the teams eliminated in the first round of the league playoffs. In the final, the team won to the Zaragoza led by Pepe Laso in Villanueva de La Serena (Badajoz). José Antonio Querejeta was the top scorer of the game with 30 points and the team earned the qualification to the Korać Cup for the following season. At the institutional level, Jose Antonio Santamaría is again the club president. The 1985–86 season was marked by the Korać Cup debut. The first rival was the Dutch Super Cracks Werkendam, which was clearly defeated at home (73-88) and overwhelmingly in Vitoria-Gasteiz (130-94). The next rival was the French ASVEL. In the home game, the Basque team fell against the French team 84–94, but this defeat did not undermine the team hopes to seek the comeback weeks later in Lyon. The game played in the French town at the end of game resulted in a draw at 88 points, but the competition system computed the difference in points of both clashes and meant the elimination of the Basque team from the competition.
