However, Hill was not close enough and with Ellison responding with a series of good lap times towards the end of the race, the race one winner couldn't make it a double, Ellison holding on to record his fifth BSB victory.
Behind Hill, who now takes an early lead in the overall standings, was Seeley, who gave Relentless by TAS Suzuki its first ever BSB podium in third, while fourth place Laverty completed the team's best-ever weekend.
Easton held off Rutter to complete a solid set of results on a weekend where he has struggled somewhat with his knee injury, while John Laverty got the nod over fellow Kawasaki man Simon Andrews in the battle for seventh.
Martin Jessopp made it two Ridersmotorcycles.com Ducatis inside the top ten, the former Cup rider scoring his career-best result in the process, while Steve Brogan capitalised on the attrition rate to give his Evo-specification Jentin BMW a fine tenth place finish.
Outside the top ten, Adam Jenkinson, Luke Jones, Christian Iddon, Steve Mercer and Hudson Kennaugh all opened up their BSB points accounts with a run to 11th, 12th, 13th, 14th and 15th respectively.
