(CNN) -- American Levi Leipheimer has completed his victory in the Tour of Castilla and Leon in northern Spain, following Friday's 152.5km fifth and final stage from Benavente to Valladolid.
Spain's Alejando Valverde took the honors in a sprint finish, his second stage victory of the race, pipping Caisse D'Epargne team-mate Jose Joaquin Rojas and Euskaltel rider Pablo Urtasun, in a time of three hours, 17 minutes, 46 seconds.
Leipheimer finished safely in the peloton to secure his second major success of the season, following-on from his Tour of California win last month, by 16 seconds from Astana team-mate Alberto Contador with David Zabriskie of the Garmin team in third place overall.
Contador was bidding to win the race for a third consecutive year, but lost ground to Leipheimer in the individual time-trial and helped protect his team-mate's lead over the final two stages.
The Astana team underlined their strength by finishing first and second overall, and would undoubtedly have had Lance Armstrong challenging as well had the seven-time Tour de France winner not crashed in Monday's first stage, breaking his collarbone in the process.
