Michael Matthews takes 5th stage

LAGO DE SANABRIA, Spain -- Michael Matthews of Australia won the fifth stage of the Spanish Vuelta on Wednesday, and Vincenzo Nibali of Italy kept the overall lead ahead of Christopher Horner of the U.S.

Matthews, riding for Orica-Greenedge, won in 4 hours, 28 minutes, 22 seconds. He was followed by Maximiliano Richeze of Argentina and Gianni Meersman of Belgium. Both had the same time as the Australian for the 108-mile ride from Sober to Lago de Sanabria.

Matthews dedicated his win to teammate Wesley Sulzberger, who was ruled out of the race after breaking his collarbone and elbow during Tuesday's fourth stage.

Astana rider Nibali is three seconds ahead of RadioShack-Leopard's Horner.

The three-week race ends in Madrid on Sept. 15.
