MADRID, Aug 30 (Reuters) - Dutchman Tom Dumoulin won the ninth stage of the Vuelta, prevailing in a punishing uphill finish to claim the overall leader's red jersey on Sunday.
The Giant-Alpecin rider attacked in the final climb, a 4km ascent with an average gradient over 10 percent, and pipped Chris Froome inside the final 100 metres after the Briton had also attacked.
