The daughter of Clodovil was second on her debut at Leicester a fortnight ago and was sent off a short-priced favourite for today's contest.
She won as an odd's on shot should under Ryan Moore, travelling well throughout before striking the front at the furlong marker.
Ryan kept her up to her work and she went on to score by three and three-quarter lengths.
Roger said: "She is a straightforward filly and has won nicely. She handles soft ground very well and looks as though seven furlongs is going to be well within her capabilities."
