Kingsbarns tops Trophy list25th October 2012
Aidan O'Brien relies solely on the supplemented Kingsbarns in Saturday's Racing Post Trophy at Doncaster, the final Group One of the British Flat season.
A total of 15 entries earlier in the week has been whittled down to a field of just seven runners, but it remains a competitive contest.
O'Brien has taken out Battle Of Marengo, ante-post favourite earlier in the week, suggesting his seven-length Navan maiden winner Kingsbarns has been showing him all the right signs at home.
