Battle Of Marengo is 4/9 (from 4/7) with Paddy Power for Sunday's Derrinstown Stud Derby Trial at Leopardstown (due off 3.55pm).
The Aidan O'Brien-trained colt is 5/1 with the same firm for the 2013 Investec Derby and therefore ranks as the stable's No.1 hope for Classic glory after winning the Ballysax Stakes in his impressive fashion on his reappearance.
O'Brien has won the Group 2 Trial with two of his last three Derby heroes, Galileo and High Chapparal, and it'll be a surprise if Battle of Marengo can't emulate those horses by putting his four rivals to the sword. Paddy Power
“Battle Of Marengo looked awesome last time over course and distance. Sugar Boy couldn't live with him that day and his subsequent win in Sandown's' Classic Trial would indicate it will take a very decent horse to beat him.”
Of his four opponents, Group 2 Galileo EBF Futurity Stakes winner First Cornerstone and Group 1 Criterium International winner Loch Garman look the chief dangers. The field is made up by outsiders Little White Cloud and Don't Bother Me.
