Henry and Duke entered for Melbourne

Aidan O’Brien has given both Henrythenavigator and Duke Of Marmalade a potentially fascinating extra option by entering the pair in the Tatts Cox Plate in Australia on October 25.

O’Brien’s two multiple Group One winners are among 15 Ballydoyle candidates for the three Spring Racing Carnival feature events including the Emirates Melbourne Cup, where both triple Gold Cup winner Yeats and his potential successor in staying events, Septimus, have been put forward.
