Soriano's class and versatility were showcased at Avondale where the mother-to-be added another major title to her record.
A dual group one weight-for-age winner over 2000 metres, she had no trouble dropping back to 1400 metres to add the group two Auckland Thoroughbred Breeders' Stakes to her CV.
Yesterday's victory came just seven days after the Savabeel mare had blown her rivals away over a mile in the group two Tauranga Stakes and a field that contained five top flight winners.
Trained by Graeme and Debbie Rogerson, Soriano is raced by her breeder Denise Howell.
Soriano returned a positive test to Waikato Stud stallion Pins earlier in the week and she will have further Group One opportunities before she is retired.
