( CNN ) -- Alberto Contador wrapped up his second Giro d'Italia victory -- and sixth grand tour success -- after the 21st and final stage time-trial in Milan , won by Briton David Millar . Millar completed the 26km stage in 30 minutes and 13 seconds , with Contador taking third place , 36 seconds behind . That meant the 28-year-old Spaniard finished a comfortable six minutes and 10 seconds clear of Italian Michele Scarponi in the overall classification with another Italian , Tour of Spain champion Vincenzo Nibali , back in third place a further 46 seconds behind . Team Leopard rider Weylandt dies in Giro d'Italia crash . Saxo Bank rider Contador , who also has three Tour de France titles and one Tour of Spain success to his name , proved the dominant rider in the race after taking the leader 's pink jersey on the ninth stage to Mount Etna . He will now seek to become the first rider since Marco Pantani in 1998 to win the Giro and Tour de France in the same year . Contador won the Tour in 2007 , 2009 and last year and was only prevented from racing in 2008 because his then team , Astana , were denied a start place by organizers due to doping infringements . However , a question mark still hangs over last year 's Tour victory after Contador tested positive for a tiny amount of the banned muscle-building substance clenbuterol during last July 's race . The Spanish Cycling Federation ( RFEC ) acquitted Contador of any wrong-doing , rescinding an initial decision to give him a one-year ban after accepting the rider 's claim that he had unknowingly eaten drug-contaminated meat and was therefore not negligent . But the World Anti-Doping Agency ( WADA ) and cycling 's governing body ( UCI ) have appealed against the RFEC decision to the Court of Arbitration for Sport ( CAS ) . The case concerning Contador was due to be heard by CAS from June 6-8 in order to have the decision before the start of this year 's Tour de France on July 2 -- but CAS announced last week they had postponed the hearing to allow further preparation by all parties .
