Marvellous gave Ryan Moore a first victory in the Etihad Airways Irish 1,000 Guineas by cutting down 100-30 favourite Lightning Thunder at the Curragh this afternoon.
Trained by Aidan O'Brien, the daughter of Galileo (10-1) was having only the third start of her career in the Classic, having finished only sixth on her latest appearance in the Leopardstown trial on March 30.
Lightning Thunder, agonisingly beaten by Miss France at Newmarket, ran a fine race once again but simply had no answer to the thrust of Marvellous, who shot three lengths clear.
