The daughter of Medaglia d'Oro is from a family we know well and becomes another winner in the colours of Sheikh Ahmed.
Jockey Jack Mitchell settled Owaseyf in the midfield. She travelled strongly and cruised up to the leaders with two furlongs to run.
The runners were spread across the track but Owaseyf was in command and went on to win by two and a half lengths.
Roger said: "Owaseyf has done it nicely. She handled the fast ground well and showed a good attitude."
