By Alistair Hogg With one round still to play, Victoria has clinched the Australian Girls Interstate Teams Matches for the first time in over 20 years at Ulverstone GC, Tasmania. The Vics won the trophy on Monday afternoon with a 4-2 triumph over Western Australia, giving them an unassailable lead in the match play round robin heading into the final day. Grace Lennon put Victoria in the box seat with a first-up victory against Whitney Hillier. Stacey Shanahan and Elissa Orr then squared their match before Laura Griffin gave Victoria a two point advantage when she accounted for Tanya Kilfoil. Rhianna Davies gave the Western Australians some hope with a two-up win over Sarah Holmes, but Victorian Courtney Gay hung tight to square her match with Raychel Ray before Rachel Korevaar beat Aimee Woosman in the final match to seal a 4-2 win, and the Burrta Cheney Cup for Victoria. In other results, New South Wales pipped South Australia by just one match and Queensland thrashed host state Tasmania 5-1. Australian Girls&apos Amateur runner-up Ashley Dewhurst was overpowered by South Australian Stephanie Na before Ashley Ona, Sarah Atley and Katelyn Must all notched wins to bury the home state. South Australia will end their campaign against Victoria today who is determined to go unbeaten. Burrta Cheney is on hand to present the trophy following play and is understandably excited to be handing it over to her home state for the first time since 1984. Click here to view round four results
