PEYRAGUDES, France — Alexandre Geniez won the 15th stage of the Spanish Vuelta ending with a summit finish in his home country of France, while Vincenzo Nibali fended off his rivals' attacks to maintain the overall lead Sunday. Geniez broke away on a solo escape before the last of four category-one climbs to claim the 225-km stage starting in the principality of Andorra, passing through Spanish territory, and finishing at the Peyragudes summit. Geniez, riding for FDJ.FR, crossed the finish line in 6 hours, 20 minutes. Nibali showed his good form by responding to attacks by Alejandro Valverde, Joaquim Rodriguez, and Christopher Horner. — AP
