The daughter of Kheleyf, owned by Sheikh Ahmed Al Maktoum, showed a proffessional attitude throughout to win by three-quarters of a length.
She missed a beat at the start but was soon travelling along nicely in Andrea Atzeni's hands on the inside.

She got a little lonely in front but she was always holding the chasing pack.
Roger said: "She is beautifully bred and has been showing promise at home. It's great to get the first winner on the board."
