St Nicholas Abbey, the Classic flop who became the winner of six Group One races and the highest-earning runner in the history of Ballydoyle, lost his battle with chronic health problems when he had to be put down after an attack of colic.

Camelot and jockey Joseph O'Brien in the winner's enclosure after last year's Derby

Camelot retired with potential unfulfilled

The career of the last Triple Crown winner, Nijinsky, ended in anticlimax with defeats in the Prix de l’Arc de Triomphe and the Champion Stakes for the previously unbeaten three-year-old in the autumn of 1970. The colt who has come closest  to emulating him in the intervening years, Camelot, winner of the 2,000 Guineas and Derby in 2012 before being beaten three-quarters of a length in a St Leger which seemed his for the taking, has today been retired days short of a possible appearance in the Champion Stakes. It comes after a largely barren post-Classic campaign which included a lacklustre run in last year’s Arc and only a minor win at the Curragh in the spring before successive defeats  behind Al Kazeem in the summer.

Unbeaten as he is, for now the Derby winner is arguably not even the most accomplished thoroughbred who happens to have an engagement on Saturday. For a few hours after Ruler Of The World attempts to extend his Epsom supremacy on to home soil, in the Dubai Duty Free Irish Derby, an outstanding American champion sets a fresh challenge to such parochial perspectives as may have been re-inforced by the failure of Animal Kingdom at Royal Ascot last week.

Gary Stevens backs Oxbow to add Belmont to fairytale return

For each new scandal absorbed by the British racing community, their American cousins seem to contrive fresh consolation. Admittedly the craving for a first Triple Crown since 1978 has already been prolonged by defeat for the Kentucky Derby winner, Orb, in its second leg. But Oxbow's Preakness success none the less consolidated the romantic gains made by Orb, in himself satisfying the patient Derby quest of his admired, old school connections – notably his trainer, Shug McGaughey. Oxbow in turn restored two Hall of Fame titans, Wayne Lukas and Gary Stevens, from the shadows at 77 and 50 respectively.

Never mind that Menorah and Hunt Ball meet at Cheltenham today; or that the National winner is to be boldly returned to the fray at Ayr on Saturday; or even if Sprinter Sacre himself tops the bill at Punchestown next week. Always and unmistakably, Newmarket's first card of the season marks the formal transfer of centre stage from jump to Flat racing.

Aidan O'Brien marshals Marengo for potential Derby squad

Ryan Mania, having been detained a second night in hospital, was discharged in time to head home to Galashiels for a celebration of his breakthrough success in the Grand National. Scans did reveal that the young Scotsman suffered a minor fracture of his C7 vertebra when taking a fall from his very next mount after Auroras Encore, at Hexham on Sunday. But Mania described himself as no more than "a bit tired and sore", having otherwise suffered only soft tissue and ligament damage, and stressed his determination to be riding again sooner rather than later.

Another triumphant raid for O'Brien

Whatever differences may persist between them elsewhere, on Dubai World Cup night at least Coolmore and the Maktoums seem to have become best of enemies. Since finding the prize-money at Meydan too lavish to resist, three years ago, his patrons have sent Aidan O'Brien to the homeland of their traditional antagonists with decorous compliments and sharp racehorses.
