Juan Jose Cobo (Fuji-Servetto) has won today's fourth stage of the 2009 Vuelta a Castilla y Leon in Spain.
Cobo launched a late attack on the final climb of the day, leaving a group of overall favourites in his wake. They were led home by Denis Menchov (Rabobank) eight seconds adrift of the Spanish winner.
Ireland's Philip Deignan (Cervelo) put in a great ride to finish in fifth.
Levi Leipheimer (Astana) finished eighth on the stage, one second behind Menchov. He maintains his overall lead of the race, with team-mate Alberto Contador in second spot, 16 seconds behind. David Zabriskie (Garmin-Slipstream) is third, 22 seconds behind fellow American Leipheimer.
The final stage of the race takes place tomorrow, a 152.5km jaunt from Benavente to Valladolid.
