Harasiya is on course to test her mettle at Group One level in next month's Moyglare Stud Stakes at the Curragh.
John Oxx's charge made a winning debut at Leopardstown in June before following up in a Group Three event back at that track.
My Special J's was back in second that day but managed to reverse the form when the pair met in the Debutante Stakes last weekend.
Oxx retains plenty of faith in his filly and believes she deserves a shot at the Group One on September 9.
"Maybe the winner improved a little bit the second time, but I'm not sure if our horse was quite at her best," he said.
"She ran well enough though and we will look towards the Moyglare with her as planned."
