VALDEZCARAY, Spain, Aug 21 (Reuters) - Australian Simon
Clarke won stage four of the Tour of Spain on Tuesday while home
rider Joaquim Rodriguez took over as race leader.
Germany's Tony Martin came second to Orica-GreenEdge rider
Clarke on the summit finish at Valdezcaray. Kazakh Assan Bazayev
was third.
Rodriguez replaced Alejandro Valverde as race leader after
his fellow Spaniard crashed 20-km from the summit.
The race ends on Sept. 9.
