Prepared by Justin Snaith, Oh Susanna won the Group I Cartier Paddock Stakes at her previous outing and was the only three year-old filly in the 18 horse field.
She powered to the line to win the 2000 metre feature by half a length becoming the first three year-old filly to win the race since 1905.
Another freakishly good daughter of Darley's much missed Street Cry, who has also given us Winx and Zenyatta, Oh Susanna has won three of eight starts more than justifying the big price paid for her dam Sharp Susan (USA) in 2012.

Purchased on behalf of South African based Drakenstein Stud, Sharp Susan was sent to stud initially in Australia before being sent to the Northern Hemisphere in 2016.
Foaled and raised at Coolmore before being sent to South Africa as a yearling, Oh Susanna is the third winner for Sharp Susan, whose first foal Indiano Jones was Group II placed in the US and whose second, Biblical Susan, is a winner in South Africa.
The current two year-old from Sharp Susan, a colt by Exceed and Excel, was sold at Inglis Easter last year for $300,000 to Snowden Racing and was consigned by Coolmore. He has been named Signore Fox and is trained by Peter and Paul Snowden for Waratah Thoroughbreds.
Sharp Susan's last Australian bred foal is a yearling filly by Fastnet Rock.

Not offered at auction, Traces runs for his co-breeder Arrowfield Stud in partnership with Ridgemont Racing and is the first foal of unraced Traceability, a half-sister to Group I winners Master of Design and Suntagonal.
Arrowfield Stud sold a t here-quarter brother by Redoute's Choices to Traces at the rcenet Magic Millions Yearling Sale for $750,000 to Hawkes Racing.
Traces is the 77th stakes-winner for champion sire Snitzel.
