Having finished second in a Group Two at the Curragh on her previous start for Jessica Harrington, the daughter of Galileo made the most of a drop down to Listed level in the mile-and-a-quarter contest.
Kept handy throughout by Colm O'Donoghue, the 9-4 favourite quickened away smartly once sent on inside the final quarter of a mile to cross the line with two and a half lengths to spare. Vintage Folly was a clear second.
O'Donoghue said: "It's a good training performance by Mrs Harrington, to be fair. She pointed out little niggly problems early on in the season and worked on them. She has done a great job.
"Physically every day I get on her she is a stronger filly. She travelled extremely well and she moved great and she deserved that.
"I am starting to think she wants the ease in the ground and that's what she came here for. She is a beautiful-moving filly and she's done it well."
