Calzati swoops and conquers
The 27-year-old, riding for the A2R team, produced a dominant display to win all four categorised climbs before breaking away from a six-man pack with 28km remaining to win with ease.
Kjell Carlstrom and Patrice Halgand finished second and third, respectively, in the 181km stage while a strong sprint finish saw Australian Robbie McEwen retain the green jersey.
