Ante-post market moves indicate Middle Park Stakes winner, Minardi, is the O'Brien first string. Frankie Dettori's booking for ante-post favourite, Tobougg, rather than riding in the Kentucky Derby the same day has hardened support for the Godolphin colt. Stable companion, Rumpold, is also a likely runner but West Order is more likely to tackle the Irish 2,000 Guineas on 26 May.
