Curraghmore graduate Aspect Ratio will be looking to score an upset victory in Saturday's Gr.1 Surround Stakes.
Aspect Ratio will be one of the outsiders at Randwick against a quality field of fillies led by Funstar, Flit, Lyre, Kiamichi and New Zealand raider Probabeel.
Last week John Sargent produced a Gr.2 Hobartville Stakes (1400m) upset with Brandenburg and is hoping for a repeat performance.
While Sargent is realistic about the chances of pulling off boilover results on successive weekends, he has not ruled serving up a repeat dose.
"You'd love to because it is a very strong field," Sargent said.
"Aspect Ratio's whole campaign is being centred around winning the ATC Oaks so this is a kick off point for her."
Sargent resisted the temptation to pursue a VRC Oaks campaign with Aspect Ratio in the spring, opting instead to focus on the Sydney classic.
A daughter of Declaration Of War, the sire of Melbourne Cup winner Vow And Declare and Victoria Derby winner Warning, Aspect Ratio might find her Surround rivals too sharp over 1400m but Sargent expects her to emerge as a potent force over longer distances.
"I didn't take her to the Oaks in the spring. It can be pretty hard on them at that age and a lot of them don't seem to come back in the autumn," Sargent said.
"So I shied away from that and she will be spot-on for this one in about six weeks time.
"She is as serious a staying filly as I've had."
A $75,000 Karaka Book Two purchase for Sargent from the Curraghmore draft, the David Butler-bred Aspect Ratio is the second winner from Group Three placed Poste Restante, who won up to 2400 metres and was also fourth in a New Zealand Oaks. -AAP
