Matteo Trentin beat Spaniard Juan Jose Lobato in a final straight sprint to win stage four of the Vuelta A Espana while Chris Froome retained the overall lead.
Italian Quick-Step Floors rider Trentin completed a hat-trick of stage wins in grand tours, adding victory in the Vuelta to the Tour de France and the Giro d'Italia.
He rode the 198.2km route from Andorra's Escaldes-Engordany to Tarragona, Catalonia in 4 hours 43 minutes 57 seconds.
"I was really looking for this stage win because I'm really going well in this last part of the season," Trentin told reporters.
"After my crash that spoiled my time in the Tour de France, I was just thinking about coming here and winning stages."
