Ground will dictate the summer programme for Australia, Saturday's easy Investec Derby winner, according to Aidan O'Brien. The trainer intimated that his colt would only run on good going or faster, which will help determine whether the Irish Derby is preferred to the Coral-Eclipse as an immediate target.
Three decades ago, when Vincent O'Brien sent out Golden Fleece to be his sixth Derby winner at Epsom, it seemed beyond the realms of possibility that two trainers would later saddle five Derby winners apiece.
Yet, Sir Michael Stoute, who at that stage had enjoyed a solitary success, with Shergar (1981), and now Aidan O'Brien, who did not take out a licence until 1993, are poised just behind the acknowledged maestro on the Roll Of Honour.
Three trainers have trained seven Derby winners: Robert Robson and John Porter in the 19th century and Fred Darling in the first half of the 20th century. With the current prolonged domination of the middle-distance ranks by the Ballydoyle/Coolmore operation, Aidan O'Brien, who made history on Saturday when completing a hat-trick of Derby winners, is now at a short price to break their record.
John Magnier, the driving force behind Ballydoyle/Coolmore, was enjoying Derby success for the eighth time as an owner when Australia sailed home a comfortable winner.
