LAGOS DE COVADONGA Spain (Reuters) - Poland's Przemyslaw Niemiec won the 15th stage of the Tour of Spain as Alberto Contador moved further ahead of Britain's Chris Froome at the end of a gruelling final ascent on Sunday.
Spaniard Contador, who retained the overall leader's red jersey, battled against the negative tactics of Alejandro Valverde, second overall, and Joaquim Rodriguez to finish a few seconds behind his two compatriots.
