The daughter of Galileo, sent off the 2/1 favourite, overcame greenness to win under Jamie Spencer.
She broke slowly from the stalls and was settled towards the rear before passing the whole field to take over the running with three furlongs to run.
She showed inexperience and idled a little in front but was always holding the eventual second Rippled, winning by a head.
Roger said: "She has been ready to run for a while but we have just been waiting for better ground. She has been working nicely so it's great to get a win under our belt before hopefully going on to better things."
Moratab made a promising debut to finish second at Hamilton while Boogie Shoes ran his normal consistent race to also finish second in a mile handicap at Newmarket.
