Sagan wins Tour de France Stage 3 BOULOGNE-SUR-MER, France, July 3 (UPI) -- Peter Sagan of Slovakia won the third stage of the 2012 Tour de France Tuesday, but Swiss rider Fabian Cancellara still holds the front-runner's yellow jersey. In claiming his second stage win, Sagan, who also won Stage 1 Sunday, finished the 197-kilometer trek from Orchies to Boulogne-sur-Mer in 4 hours, 42 minutes and 58 seconds. That was a second faster than a large group that included Cancellara. Cancellara won the prologue Saturday and is still 7 seconds ahead of Britain's Bradley Wiggins and Frenchman Sylvain Chavanel, who led for most of the final 5 kilometers Tuesday before being caught. Defending champion Cadel Evans of Australia finished sixth Tuesday and is 17 seconds off the lead pace. Stage 4 will cover 214.5 kilometers from Abbeville to Rouen Wednesday, with riders rolling along the English Channel coast for most of the way before heading inland. It features four Category 4 climbs.
