Seven the magic number for Aidan O’Brien

Seven is the magic number for Aidan O’Brien at Epsom today as he sends out seven runners in search of his seventh victory in the Investec Derby. Three trainers have saddled a septet of winners in the race’s 238-year history, so O’Brien would be joining an elite club if he can emulate that achievement.

Chester Vase winner Sir Dragonet spearheads this year’s challenge in the hands of Ryan Moore, as he tries to continue what has been a rapid upward trajectory over the last month. The Camelot colt did not make his racecourse debut until April 25, and O’Brien is hoping that patience can pay dividends after the Coolmore team paid the £85,000 required to supplement him for the race on Monday.
