Irishman Alastair Seeley won the feature Superbike race to complete a double at the North West 200 on Saturday.
The British Supersport champion – who also won Thursday's Superstock race to make it three victories at the meeting – had earlier secured three second-place finishes.
Michael Rutter joined Joey Dunlop on 13 wins at the North West after victory in the Superstock race.
Rutter is now the joint second most successful rider at the North West and sits two behind the late Robert Dunlop.
Ballymoney's William Dunlop won the opening Supersport race, while John McGuinness earned his sixth NW 200 victory in the first Superbike race.
Morecambe man McGuinness finished ahead of Seeley with Australian Cameron Donald in third.
Conor Cummins and Dan Kneen were the best of the locals with seventh and eighth place finishes.
