Peter Sagan gets his third stage win at Tour de France

After most of the other top sprinters at the Tour de France succumbed in the Alps, Peter Sagan was in prime position to dominate Friday’s flat finish.

Cycling’s world champion did not disappoint, timing his move to reach maximum speed as he swung past two challengers to claim Stage 13 by a wheel length and take his third win of this race.

Seconds after Sagan reasserted his status as the most feared finisher left on the Tour, overall leader Geraint Thomas safely crossed in the pack along with teammate — and nearest challenger — Chris Froome.

Behind about 20 riders with a kilometer to go, Sagan charged to overtake runner-up Alexander Kristoff and Arnaud Demare, who finished third, at the finish line.

Sagan’s 11th career win at the world’s biggest bike race came after he was the fastest to the line in bunch sprints on Stages 2 and 5.

This time, Sagan was racing against a field of sprinters greatly depleted by three grueling days in the mountains.

Fernando Gaviria and Dylan Groenewegen, who both won two stages on this Tour, along with Andre Greipel all abandoned the race on Thursday, while 30-stage winner Mark Cavendish and Marcel Kittel failed to make the time cut on Wednesday.

Sagan said their absence made sprinting “messy.”

“It’s changed,” he said. “Everybody wants to do a sprint now. It’s pretty messy.”

Facing no attacks on the flat stage, Thomas had no trouble maintaining his advantage of 1 minute, 39 seconds over defending champion Froome.

Tom Dumoulin stayed third overall at 1:50 behind. Primoz Roglic was fourth at 2:46, and Romain Bardet was fifth at 3:07 back.

The 169.5-kilometer (105-mile) leg starting from Bourg d’Oisans at the foot of the Alpe d’Huez delayed the resolution to the burning question of this race: Is Thomas really the Sky team’s top option while Froome seeks a fifth Tour title?

Thomas has said that although he would work to support Froome, he is not going to intentionally lose time.

But with Thomas so far proving to be the stronger rider, even in the mountains where Froome normally makes his mark, their team appears ready to let the road decide.

“We’ve got two cards to play and it’s good for our strategy,” Sky sports director Nicolas Portal said before Friday’s stage.

“Who knows how long [Geraint] can hold this top level? Same for Froomey. The most important thing is the group is strong and we have the best position.”
