Mark Cavendish timed his sprint to perfection to win the fourth stage of the Tour of Switzerland.
The 29-year-old completed the 160.4km leg from Heiden to Ossingen in three hours 35 minutes three seconds.
Fellow Briton Sir Bradley Wiggins crashed in the closing stages and finished almost 12 minutes behind.
Cavendish's Omega Pharma - Quick-Step team-mate Tony Martin retained his six-second overall lead from Tom Dumoulin, with Wiggins almost 14 minutes adrift.
Team Sky sports director Dan Frost said of Wiggins: "He sustained grazing and bruising to the muscles on his right leg, which will be treated overnight and the team doctor will be reviewing his injury in the morning.
"Bradley has been carrying a mild chest infection from the weekend so he has been taking antibiotics and his condition has improved. Racing with this illness has affected him a bit, but he's shown his commitment and has worked really well for the team."
