Narvaez previously rode for Ineos Grenadiers
Ecuador's Jhonatan Narvaez won stage four of the Giro d'Italia, just three days after being involved in a major crash which resulted in three of his UAE Emirates-XRG team-mates being forced to abandon the race with serious injuries.
Narvaez, 29, comfortably out-sprinted Colombia's Orluis Aular of Movistar in the uphill finish in Cosenza in southern Italy.
Italy's Giulio Ciccone of Lidl-Trek was third and claimed the overall leader's pink jersey after previous leader Guillermo Thomas Silva of Uruguay finished more the 12 minutes behind.
Britain's Ben Turner of Netcompay Ineos Cycling was fourth after helping team-mate Egan Bernal of Colombia recover from losing ground on the stage's category two climb.
