CUENCA, Spain (Reuters) - David Millar won stage 14 of the Tour of Spain on Saturday and Spaniard Alejandro Valverde, who came in fourth, maintained the overall lead.

Second in the 33 km hilly time trial starting and finishing in Cuenca was Swiss rider Fabian Cancellara and third Kazakh Alexander Vinokourov.

Valverde's fourth place, 13 seconds behind Millar, means he has increased his lead over Kazakh Andrey Kashechkin.
