Dutchman Bauke Mollema (Belkin) took an opportunistic win on stage 17 of the Vuelta a Espana after crosswinds wreaked havoc on the bunch after the second rest day.
The all-rounder, whose overall chances faded on stage eight's summit finish, made his lone bid for victory inside the final kilometre of the stage while the thinned out chasing bunch were caught playing games behind.
Edvald Boasson Hagen (Sky) once again narrowly missed out on a stage win and had to settle with leading the bunch across the line for second.
The majority of the overall classification favourites managed to hold onto their positions in the lead echelon, however Thibaut Pinot (FDJ) and Domenico Pozzovivo (Ag2r-La Mondiale) both lost 90 seconds after getting caught out in the crosswinds.
Crosswind hurricane
On one of the Vuelta's rare flatter days, containing just two third category climbs, the scene looked set for a sprint finish.
Francesco Javier Aramendia (Caja-Rural) and Adam Hansen (Lotto-Belisol) attacked early, building up a lead of over eight minutes at the 50km mark. However under pressure from Orica-GreenEdge and Lampre-Merida the gap steadily fell until the pair were caught with 21km to go.

Yet as it did on stage 13 of this year's Tour de France, the hot blast of the wind across the bare, open fields caused the bunch to wilt and splinter under sustained pressure.
Fabian Cancellara (Radioshack), riding his final stage of this year's race before leaving to prepare for the world championships time trial, did most of the damage before Saxo-Tinkoff reprised their role at the head of affairs and consolidated their lead.
As the thinned out bunch made it over the small climb on the run in to Burgos and slowed to prepare itself for a sprint, Mollema seized the perfect opportunity in the confusion and couldn't be caught.
