IRISH Derby winner Latrobe narrowly failed to give trainer Joseph O'Brien another major success when beaten a head in the Group 1 Seppelt Mackinnon Stakes at Flemington early this morning.

The three-year-old was beaten a head by the Jarrod McLean-trained 25/1 shot Trap For Fools – a second top-level winner for late Dalham Hall Stud stallion Poet's Voice – with last week's Group 1 AAMI Victoria Derby hero Extra Brut another head back in third.
