Finhaut-Emosson (Switzerland): Chris Froome rubber-stamped his Tour de France domination by putting time into his rivals as Ilnur Zakarin won yesterday's 17th stage.

Colombia's Nairo Quintana was the big loser, struggling in the final 2km and giving up another 28sec to Froome, who pulled clear of all his main rivals except Australian Richie Porte. Zakarin won the 184.5km Alpine stage from Bern to Finhaut-Emosson in Switzerland by 55sec ahead of Sunday's 15th stage winner Jarlinson Pantano of Colombia, with Poland's Rafal Majka third at 1min 26sec.

But behind that, defending champion Froome followed an attack from Porte that none of his rivals could follow, with Quintana looking particularly vulnerable.
