Sheikh Ahmed's daughter of Shamardal was a non-runner on account of the soft going at Doncaster on Saturday but made a winning debut over seven furlongs yesterday.
She was always to the fore under Jack Mitchell, tracking the leaders before hitting the front at the furlong marker.
Jack never had to ask his mount too many questions and she went on to win decisively by a length.
Roger said: "She has been working nicely at home and showing plenty of speed. That probably wasn't the strongest of maidens but she has done it well."
Since Friday: Perfect Heart, Talmada, Reesha, Eton Forever and Rekhdat have all been successful.
