The daughter of Starspangledbanner provided leading Australian jockey Chad Schofield with a first win in the UK.
He gave her a lovely ride, dictating matters from the front and kicking as they went downt the hill.
Victory never looked in doubt and she went on to win by over four lengths.
Roger said: "She won nicely. It wasn't a strong race but it was good to get her head in front. She is a speedy filly and we shall probably look to keep her at sprint distances for now."
