He's worn it for two days, but Mark Cavendish relinquished the Maglia Azzurra, the leader's jersey, at the Tirreno Adriatico on Friday.
Now heading the general classification is Cavendish's Omega Pharma - Quick-Step teammate Michal Kwiatkowski, with fellow OPQS rider Rigoberto Uran second.
Today's stage was won by Cannondale's Slovakian all-rounder Peter Sagan.
Peter Kennaugh played his part in Team Sky's effort to get Richie Porte into a decent finishing position and he duly obliged, coming home six seconds behind the leaders.
The tour heads into the mountains on Saturday for a finish more than 1500 metres above sea level.
