Dominic Herbertson won four races at the Cookstown 100

Dominic Herbertson shone at the Cookstown 100 road races on Saturday with a four-timer.

The Hexham rider won the feature race, the Open event, the Supersport class and the Moto3 outing over the 2.1-mile Orritor circuit.

Michael Sweeney added a Supertwins success to his victory in Friday's Supersport Invitation race.

Michael Dunlop did not compete in Saturday's racing after winning the Open Superbike Invitation race but then crashing in the Supersport event the previous day.

Herbertson came out on top in the headline Cookstown 100 after a thrilling 12-lap duel with MJR BMW-mounted Skerries man Sweeney.

The Englishman's margin of victory at the chequered flag was just 0.175 seconds.

Earlier Burrows Engineering/RK Racing pilot Herbertson romped home by 30 seconds on his BMW from Neil Kernohan in the Open race.

Saturday's Supersport was another close encounter, with Herbertson getting the better of rival Sweeney by 0.5 seconds with both competitors aboard Yamahas.

Darryl Tweed was the lightweight victor.
