FORLI, Italy — Italy's Nicola Boem of the Bardiani team won the 10th stage of the Tour of Italy Tuesday with Spanish great Alberto Contador retaining the leader's pink jersey. Boem crossed ahead of three Italian breakaway rivals — Matteo Busato, Alessandro Malagatu and Alan Marangoni. It was the biggest win for 25-year-old Boem since turning professional in 2013. Boem, whose team is made up of young Italian talent who are regularly invited to compete in the race by the organizers, said: “We were targeting a stage win at this Giro, and it has come in the flattest, most unlikely stage. “We worked together and with 20km to go we had a good advantage. With 1.5km to go, Alan Marangoni attacked. “I knew I couldn't let him get away so I just gave it everything. I dedicate the win to my teammates, who are probably even happier than I am, and to my girlfriend Federica, who has believed in me and encouraged me every day at this Giro.” Australian Richie Porte, who had been sitting third going into the stage just 22sec behind Contador, lost ground on his rivals, a puncture in the final five kilometers costing him dearly. Even though several of his teammates waited for him and tried to help him get back to the peloton the 30-year-old was barely able to stick with his Sky colleagues and dropped to 1min 09sec behind the Spaniard. Contador, who is bidding to become the first rider to pull off the Giro/Tour de France double in the same season since the late Marco Pantani in 1998, sympathized with Porte and revealed he hadn't found the stage easy either. “It was anything but an easy day,” said the 32-year-old. “Every day at the Giro can hold surprises. “The other day it was my crash. Today Richie had an unfortunate puncture. It is always annoying to lose time that way although, with everything that lies ahead of us, the time lost is very small.” Porte's team sporting director said he hoped such mishaps would not influence the overall outcome. Wednesday's 11th stage covers 153km from Forli to Imola. — AP
