Trek's Julian Arredondo celebrated a solo victory atop Valsugana at the Giro d'Italia in what was a day for Colombian riders with Fabio Duarte finishing second and Nairo Quintana holding onto the maglia rosa.
Ulsterman Philip Deignan of Team Sky showed an exceptional zeal placing third on the summit finish – 37 seconds behind winner Arredondo who marked his maiden Grand Tour stage victory in the blue jersey of the mountain classification leader.
Deignan is the first Irishman to finish on the podium of a Giro stage since Hall of Fame inductee Stephen Roche placed third in a time trial in 1989.
The 171km mountain stage saw a shake-up in the general classification with Cadel Evans (BMC) dropping from third to ninth overall having lost contact on the 16.85km final climb that featured maximum gradients of 14 per cent.
Deignan and team mate Dario Cataldo were part of a 14-man break that approached the base of the last ascent together, the Donegal man going on to enjoy a well-earned taste of glory ahead of today's mountain time trial.
