Frenchman Arnaud Demare won a sprint finish to claim the fourth stage of the Giro d'Italia on Tuesday, with Portugal's Joao Almeida holding onto the leader's pink jersey. Groupama-FDJ rider Demare pipped Slovak Peter Sagan and Italy's Davide Ballerini in a thrilling battle to the line after the 140km ride from Catania, the last stage in Sicily before the race heads for mainland Italy. jm/ea/iwd
