In scorching conditions around the 8.9-mile ‘Triangle’ course, Irwin and Milwaukee BMW’s Davey Todd engaged in a repeat of their battle in Thursday’s opening race, which went down to the sixth and final lap.
With nothing between them, Todd was lining up a pass as they approached Juniper chicane but a slower rider skittled his tactics, preventing the 28-year-old from executing his plan.
That left Hager PBM Ducati’s Irwin to clinch an historic win by 0.382s for a double following his victory in Thursday’s race.
Michael Dunlop finished third on his Hawk Racing Honda, 19 seconds down, despite incurring a 10-second time penalty after failing to stop when he ran on at Magherabuoy chicane on the first lap.
Irwin wrapped up his 10th Superbike victory in a row and his seventh on Ducati machinery to take over as the most successful rider ever in the blue riband class from Joey Dunlop and Michael Rutter.
That left Hager PBM Ducati’s Irwin to clinch an historic win by 0.382s for a double following his victory in Thursday’s race.
