Price's preferred choice for the mare was The MRC Foundation Cup at Caulfield on Saturday but instead he lodged a late nomination for the JRA Trophy (2400m) at Rosehill.
Foreman Patrick Kearney said the decision, which came from a tip-off from Price's daughter Kelly, had clearly paid dividends.
“She's come up to Sydney in a nine-horse field and she dominated,” Kearney said.
“It was a great ride, perfect 10 out of 10 for what she needed to do – she was jumping up from 1600 metres to 2400 metres so she's come a long way and done a good job.”
Miss Admiration is likely to stay in Sydney for the Group One Metropolitan at Randwick next Saturday.
Now the winner of two races from 16 starts, Miss Admiration was placed twice at Group One level last autumn.
