Battle won for O'Brien

Battle Of Marengo made it five wins in a row but was only workmanlike in claiming victory in the Derrinstown Stud Derby Trial at Leopardstown.

Giving Aidan O’Brien his fourth Derby trial winner of the week, the Galileo colt – sent off at prohibitive odds of 2-13 – took over from Dont Bother Me around five furlongs out and it looked like he would win with real ease when going clear with quarter of a mile to run.
