The double win comes after a so-far disappointing showing in the northern classics, where they have yet to seriously trouble the opposition.
Stage 2 saw a summit finish and a change of tactics from Sky who allowed the domestique, Siutsou, to initiate a late breakaway and solo to victory after dropping his compatriots Pierre Rolland (Europcar) and Stefano Pirazzi (Bardiani-CSF Inox).
The Belarusian took five seconds from Mauro Santambrogio (Vini Fantini) with Nibali and Wiggins a further 18 seconds back in third and fourth respectively.
Nibali had attacked Wiggins no less than three times on the run in to the finish but each time the Londoner was happy to maintain his pace and slowly reel in the Italian.
Wiggins now sits fourth overall, 3:48 behind leader Maxime Bouet (Ag2r-La Mondiale) who, along with second-placed Pavel Kochetkov (Rusvelo), benefitted from discord amongst the big teams which allowed the stage 1a breakaway to stick.
Siutsou sits second, with Nibali in fifth at nine seconds behind Wiggins in this fascinating warm up to next-month’s Giro d’Italia.
