Sanchez, riding for local favorite Euskatel-Euskadi, rode through steady rainfall to clock the fastest mark in the 11.7-mile time trial around the medieval village of Onati.

Rodriguez was the overall runner-up 12 seconds back, while Bauke Mollema of the Netherlands was third.

Rodriguez entered the sixth and final day nine seconds ahead of Sanchez. But the Movistar rider finished the stage in sixth place, 22 seconds off the winning pace.
