Perth filly Delicacy continued her rampage through the three-year-old staying ranks with another dominant win in Saturday’s Group I South Australian Derby at Morphettville.

Delicacy’s amazing run of Group wins started with her success in the Group III WA Oaks (2400m) on March 28 before continuing to the Group II WA Derby a fortnight later.

A cross-country flight to Melbourne and an eight-hour float trip to Adelaide failed to stop Delicacy winning the Group I Australasian Oaks at on May 2 before backing up seven days later for another impressive success.

Peter Hall filled in again for the injured William Pike and the experienced jockey had to get the filly settled after she received a check in the back straight.

The Grant Williams-trained Delicacy was among the backmarkers as the field rounded the home turn but her outstanding motor propelled the daughter of Al Maher to her top with 200m to run.

Delicacy, the $1.90 favourite, swamped the brave Godolphin galloper Allergic ($18) with 100m to run before powering away to score by 1-1/2 lengths over the honest Kiwi Werther ($12), who grabbed second from Allergic in the last 25m.

Delicacy became the first filly to complete the Australasian Oaks and South Australian Derby double since Zarita in 2008.

Meanwhile, the Adelaide gallopers closed out the day with a win when Magic Boy finished powerfully in the Listed Adelaide Guineas (1600m).

The Ciaron Maher-trained Duibio started favourite but wilted in the last 100m after surprisingly leading but Magic Boy came from well back to beat Distant Rock and Actuariat.
