Vincenzo Nibali rode to a second consecutive victory at Tirreno-Adriatico after holding off Chris Froome on the final-stage time trial.
The Italian (Astana) stayed calm despite losing a handful of seconds to the Team Sky rider to clinch the maglia azzurra by 23 seconds in San Benedetto del Tronto.
The foundations of the victory had been laid with a last-ditch attack on Monday's sixth stage in which powered away from Froome. The Briton fought back on the final day's 9.2km time trial, but was only able to take 11 seconds out of his rival, setting the sixth quickest time in the process.
Alberto Contador beat Joaquim Rodriguez (Katusha) to elevate himself on to the final place on the podium, yet the Team Saxo-Tinkoff rider came under intense pressure at the death from Michal Kwiatkowski (Omega Pharma - Quick-Step), just edging out the Pole by a single second.
After crossing the line, a victorious Nibali said: "I'm really, really happy to win Tirreno. It's something really important to win and it's my first victory of the season. This is more important than last year because of all the riders who came like Froome, Rodriguez and Contador."
