GAP, France - Chris Froome was reminded just how quickly the Tour de France title could slip from his grip as his Sky teammate Geraint Thomas suffered a freak crash in Monday's 16th stage. The day's laurels went to Spaniard Ruben Plaza Molina although the action was way behind as Froome's key lieutenant Thomas was sent flying off the road. In a tricky final descent Thomas bumped into Frenchman Warren Barguil and collided head first into a telegraph pole, disappearing over the road into the vegetation.?"I was just taken out," said Thomas. The Welshman, who is sixth overall, was quickly back on his bike and reached the finish incurring only minor losses. "I apologize I wanted to brake just before the bend but (American) Tejay van Garderen pushed me with his shoulder and my finger slipped from the brake lever, I'm sorry," said Barguil. Froome, who also lost teammate Peter Kennaugh as the British champion abandoned the race, said: "He's OK he's a tough guy he's going to be up there in the Alps." The incident brought back memories of the 2003 Tour, when Spain's Joseba Beloki, who was trailing Lance Armstrong in the overall standings, attacked on the same descent and crashed out of the race. Armstrong avoided Beloki and in the process cycled down the hill across a small field and, after jumping over a ditch, rejoined the road. Among his main rivals, only Alberto Contador attacked Froome in the climb up the Col de Mense but the Spaniard could not open up a telling gap. Defending champion Vincenzo Nibali, who fell out of contention in the Pyrenees, also attacked to pull away but Froome did not bother chasing the Italian on another hot day on the Tour. Plaza Molina of the Lampre team won solo after a 201-km ride from Bourg de Peage, attacking a group of breakaway riders in the final climb of the day. Slovakian Peter Sagan of Tinkoff-Saxo was second for the fifth time on the Tour this year despite riding spectacularly in the descent, while Colombian Jarlinson Pantano took third place for IAM Cycling. Froome still leads Van Garderen by three minutes and 10 seconds and third-placed Colombian Nairo Quintana who is 3:32 off the pace going into Tuesday's rest day. The race will then enter a crucial spell with four grueling stages in the Alps. — Reuters
