Scott Redding had the most confidence of the lead trio in the wet, but was quick to praise his rivals after a cut short BSB race one at Donington Park.
Max Cook was out front when the rain arrived, but secured second by not letting up before the BSB race was declared in the first outing at Donington Park.
Kyle Ryde took a cautious approach as a downpour arrived while leading, with a brave Scott Redding putting in a pass that saw him the winner of the first BSB race at Donington Park.
