World champion Peter Sagan sprinted to another victory in the Tirreno-Adriatico race, while Nairo Quintana retained the overall lead after the fifth stage on Sunday.
Sagan, who was also fastest on Friday, edged out Thibaut Pinot and Primoz Roglic on the narrow, cobbled climb to the finish of the 210-kilometer (130-mile) ride from Rieti to Fermo
Bora-Hansgrohe's Sagan worked his way back up to the front bunch with 2 kilometers left and easily won out of a group made up largely of riders targeting overall victory.
"It was crazy. It looked like there was no tomorrow. The peloton went so fast," Sagan said. "I'm very happy with my win today. It wouldn't have happened without (Rafal) Majka, who pulled a lot.
"After the climbers attacked, luckily there was a bit of flat road that allowed me to come across and sprint for the win."
