Trained by Justin Snaith, Oh Susanna was a winner at two and finished second in the Group I Cape Fillies Guineas at her previous start.
She proved far too good in this 1800 metre assignment, powering clear at the finish to win by a length and a half taking her overall record to two wins and three placings from seven starts.
Foaled and raised at Coolmore, before being sent to South Africa as a yearling, she 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.
Sharp Susan produced a filly by Fastnet Rock in 2016 and was subsequently sent to the Northern Hemisphere.
Oh Susanna has the honour of becoming the 20th Group I winner for Darley's much missed Street Cry, the sire of our Australian Horse of the Year Winx.
