The daughter of Dubawi won her maiden at Chelmsford in early January and was given an opening mark of 73.
She was settled towards the rear of the field under Jack Mitchell and relaxed into a good rhythm.
She cruised up to the leaders with two furlongs to run before quickening clear to win impressively by three and a half lengths.
Roger said: "I was pleased with that. She raced professionaly and I liked the way she travelled into it. I think we'll probably give her an easy time and get ready for something on the turf."
