Why this filly
This is an opportunity built around a compelling mix: the speed and toughness of an elite Japanese sprinter-miler, the influence of Frankel through the dam, and a female family that has repeatedly produced Group-class performers.
Diatonic won ten races from 1200m to 1600m, including the Group 2 Hanshin Cup and two editions of the Group 2 Swan Stakes. A son of Lord Kanaloa, he brings one of Japan’s most respected modern speed lines to Australia. As his oldest progeny are only two-year-olds, this filly gives owners the appeal of joining that story at its beginning.
Frankly Rosie is by Frankel, whose influence is recognised throughout the international thoroughbred industry. This filly is her first foal—an exciting new branch of a family already proven at elite level in Australia, New Zealand and Hong Kong.
She has the pedigree profile to generate excitement as a racehorse, while her sex and female family provide potential residual appeal beyond racing. That combination is one of the reasons well-bred fillies can offer owners such a rewarding long-term journey.

At-a-glance pedigree
Pedigree deep dive
The strength is in the balance: elite speed sources are reinforced on both sides, while Sunday Silence, Galileo and Frankel add the class and scope to suggest there may be more than pure sprinting speed in the mix.
Lord Kanaloa was an elite sprinter-miler and has developed into an internationally important sire. His best progeny range from champion Almond Eye to Hong Kong Sprint winner Danon Smash and Australian Blue Diamond winner Tagaloa. Diatonic was one of his most durable sprint-milers: a ten-time winner, three-time Group 2 winner and Group 1 placegetter.
What it may contribute: acceleration, repeatable high-class speed and the toughness to perform across multiple seasons.
Frankel is already among the defining stallions of his era. Beyond his own exceptional sire record, his daughters have produced Group 1 winners—important evidence that his influence is carrying into the next generation. Frankly Rosie introduces Frankel over a female family proven in Australasian and Hong Kong racing.
What it may contribute: athletic class, stride, constitution and the possibility of stretching speed beyond the shortest distances.
Third dam San Century produced Group 1 Hong Kong Mile winner Glorious Days and Listed juvenile winner Spurcent. Her daughter Azardi produced Group 2 Villiers winner All Legal. Spurcent’s branch later produced Group-class runners including Revolutionary Miss. It is a family with evidence at two, at the elite mile and across generations.
What it may contribute: precocity, versatility and a female line that has repeatedly converted pedigree into racecourse performance.
The displayed four-generation pedigree brings together King Kamehameha, Storm Cat and Sunday Silence above; Galileo, Danehill, Green Desert and Centaine below. There is no obvious close duplication in those four generations, giving the mating a broad international genetic base.
Our reading: a speed-led profile with enough depth underneath to make development from sprinting trips toward 1400m–1600m a reasonable possibility—not a prediction.
This filly appeals because there are multiple ways for the pedigree to work. Diatonic supplies high-class, durable speed; Frankel adds international quality as broodmare sire; and the San Century family has already produced elite and commercially relevant performers. She is a first foal, so there is discovery and upside—but also the normal uncertainty that comes with every unraced young horse.
