Fulham are on course to record their first victory in a month as they lead Doncaster Rovers 2-0 at half time of their League Cup third-round encounter.
The home side showed their intent within the first minute as Ross McCormack drove a shot at goal which was well saved.
Hugo Rodallega then blazed a shot over the bar, but set up Bryan Ruiz for the opener a few minutes later with a cushioned header.
Dan Burn doubled Fulham's lead with a close-range header on the night that he captains the side for the first time as Fulham dominated the opening period.
