Treasure the jewel in the crown of O'Brien one-two-three

Epsom runner-up Treasure Beach went one place better to give Aidan O’Brien his ninth victory in the Dubai Duty Free Irish Derby, in which the Queen’s Carlton House finished only fourth.

Colm O’Donoghue settled the 7-2 chance in fourth for much of the mile-and-a-half contest at the Curragh, with his stablemate Memphis Tennessee setting the pace.
