Spencer rides Blanco in Dubai Jamie Spencer will ride the Aidan O'Brien-trained Cape Blanco in Saturday's Dubai World Cup at Meydan. The former stable jockey to Ballydoyle and Coolmore will be partnering the Galileo colt, two times a Group 1 winner, for the first time. "Jamie will ride Cape Blanco and our Dubai horses will leave on Monday," said O'Brien at the Curragh yesterday. Spencer has been linked with a return to Ballydoyle following the departure of Johnny Murtagh last November. However, O'Brien played down the speculation by stating he would continue to use "the best available" jockeys at each individual meeting.
