The visitors were also reduced to 10 men after Julian Araujo was sent off in the 76th minute.Sevilla beat Racing Ferrol 2-1 thanks to a goal from Brazilian defender Marcao, who dedicated his first-half effort to his father who passed away on Saturday, and another from Juanlu Sanchez, who scored late in the game.Fran Manzara had equalised for Racing but received a second yellow card to be sent off in the 75th minute.
