Lausanne - Welsh rider Geraint Thomas surrendered his Tour de Romandie overall lead to Swiss rival Michael Albasini as he won both Wednesday's second stage, the 168.1km ride from Apples to St-Imier and took the yellow jersey.
Albasini, who missed out on the yellow jersey by just 63 hundredths of a second on Tuesday in the team time-trial, edged out Jarlinson Pantano of Colombia and in-form Frenchman Julian Alaphilippe, who was second in both the Liege-Bastogne-Liege and the Fleche-Wallonne in the past week.
Welsh rider Thomas finished over four minutes behind the winner at the end of the hilly stage.
Albasini's team-mate Ivan Santaromita is second, 10 seconds adrift while two-time defending champion Chris Froome of Britain is third, also trailing by 10 seconds.
Thursday's third stage is a hilly 172.5km ride from Moutier and Porrentruy, including the category two Col de la Croix.
