Operación Puerto doping case
Astana first became involved in sponsoring cycling during the 2006 season. The Spanish Liberty Seguros-Würth team was heavily implicated in the Operación Puerto doping case and the sponsors Liberty Mutual, and later Würth, withdrew their sponsorship of the team. Astana stepped in to sponsor the team, and during the second half of the season, Vinokourov won the Vuelta a España while riding for the renamed Team Astana, and his Kazakh teammate Andrey Kashechkin finished third.
