Dettori on mark with Essence of Dubai Frankie Dettori rode a superbly judged race as Godolphin`s Essence of Dubai wore down long time leader Total Impact to win the group two UAE Derby today.American jockey Gary Stevens, who landed the Godolphin Mile in the previous race, looked set for a quick double when Total Impact set sail for home 800 metres from home in the 10 furlongs (2km) test at Nad Al Sheba.Stevens`s charge drew two lengths clear but Dettori, who had settled Essence of Dubai at the back of the field, produced a storming late run in the straight to win by half a length. Ibn Al Haitham, ridden by Richard Hills, was two and a quarter lengths further back in third.Essence of Dubai finished unplaced behind Johannesburg in the Breeders` Cup Juvenile at the end of last year before returning to land the UAE Guineas at Nad Al Sheba last month.
