Spain's Omar Fraile powered to victory with a late burst in the last climb of Stage 14 of the Tour de France Saturday.
Astana's Fraile overhauled fellow escapee Jasper Stuyven - who had been away solo for 33 kilometres - on the steep climb up to the Mende aerodrome, making the catch two kilometres from the end of the 188km stage from Saint-Paul-Trois-Chateaux.
Even though the rider finished the stage at 13 seconds from stage victor Geraint Thomas (Sky), he had to be taken to the hospital of Grenoble due to some pains that he was having.
Tour de France director Christian Prudhomme has demanded fans show more respect a day after Team Sky were booed off the podium and Vincenzo Nibali crashed out when his bike got tangled up.

The Nibali incident occurred where the course narrowed and thick red smoke from spectators' flares reduced visibility and caused the Tour motorbikes to brake violently.

On Alpe d'Huez, Froome was jeered at and spat on, and one spectator was later arrested for trying to push him off his bike.
"I didn't actually notice it", he said. "I didn't want to go into the red because I knew it would be a long climb if you explode".
