Given a peach of a ride by Craig Williams, Silent Sedition stalked the pacesetting C'est Beau La Vie but needed the length of straight to gain the upper hand from that game filly to earn a second stakes win in Saturday's Group III Schweppervescence Stakes (Registered as Auraria Stakes) (1800m) at Morphettville.
Winner of the $150,000 Listed Bendigo Guineas (1400m) two starts back, the Andrew Noblet-trainee was unraced at two.
Following placings at her first three starts the daughter of War Chant finished a troubled fourth in the Group II Fillies Classic at Moonee Valley in October last year.
Off the scene for five months, Silent Sedition broke her maiden at Cranbourne on march 4 before her stakes success at Bendigo.
She was coming off a second to the in-form Bengal Cat at Sandown.
Consigned by Korilya Stud to the 2014 Perth Magic Millions Yearling sale, Silent Sedition was purchased by Aqua Trained Thoroughbreds for $45,000.
Her overall record stands at 2 wins, 2 seconds and 2 thirds from 7 starts for earnings of $144,950.
Silent Sedition's unraced dam Fiorentina (Dubai Destination) had been purchased for just $1,750 at the 2009 Inglis August Thoroughbred sale.
That's despite she is a daughter of the Group 1 Coolmore Classic heroine Porto Roco.
That looked an even more incredible bargain three years later when Fiorentina's half-brother Monterosso won the world's richest race, the Group 1 Dubai World Cup.
In 2015, Korilya Stud dispersed its bloodstock and Fiorentina made a more respectable $50,000 to the bid of Tubba Bloodstock when carrying a filly by Dick Turpin (IRE).
Fiorentina has a colt foal by Gingerbread Man and was bred back to Snippetson last spring.
Yarrandale Stud's impeccably bred Breeders Cup Mile hero War Chant (USA) (pictured) covered 58 mares last spring at a fee that was advertised as on application.
