SAINT-AMAND-MONTROND, France (AP) — A brief look at Friday's 13th stage of the 100th Tour de France:

Stage: A relatively short, flat stage for sprinters, taking riders over 173 kilometers (107.5 miles) from Tours, which is surrounded by the Loire river, to Saint-Amand-Montrond, a small town claiming to be in the exact center of France.

Winner: Mark Cavendish. The British sprinter easily beat Slovak Peter Sagan to win his second stage of the race so far and the 25th of his glittering Tour career — putting him level in third place with Frenchman Andre Leducq on the all-time list.

Yellow Jersey: Chris Froome. The British rider kept the yellow jersey but lost a considerable amount of time. He conceded 1:09 to two-time former champion Alberto Contador. Overall, Dutchman Bauke Mollema is 2:28 behind him in second place and Contador is 2:45 adrift in third spot.

Stat of the day: 9:54. The massive amount of time lost by Alejandro Valverde as he dropped from second overall to 16th. The Spaniard was left behind as he stopped to mend his bike following a puncture, could not catch up, and finished the stage itself in 70th place.

Quote of the day: "Just a reminder that I need to stay awake at all times in this race" — Froome reflecting on his time loss to Contador, who caught him cold with a well-timed late burst.

Saturday's stage: Stage 14 goes back to the hills on a rolling 191-kilometer (119-mile) trek from Saint-Pourcain-sur-Sioule to Lyon, featuring two medium climbs and five smaller ones.
