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.

Dubai Prince increases sheikh's Derby options

It has taken a while, but Sheikh Mohammed seems to be on to something here. Just two days after Casamento vindicated his decision to try his luck with Michael Halford, winning the Racing Post Trophy, another relatively cheap son of Shamardal, likewise stabled with an Irish trainer new to the sheikh's roster, produced such an impressive performance at Leopardstown yesterday that he is now quoted as short as 8-1 for the Investec Derby with Ladbrokes.

Mantoba leads Meehan's raiders

Though he saddles an unbeaten colt in the final Group One race of the domestic Flat season at Doncaster tomorrow, the real climax of Brian Meehan's campaign may yet be another fortnight away. At the same time, the complexion of the four-horse raiding party he unveiled yesterday for the Breeders' Cup – three of them being two-year-olds – testifies to the strength in depth sustaining his hopes for Titus Mills in the Racing Post Trophy.

Cecil stays level-headed while all about him lose theirs over Frankel

After maintaining his unbeaten record in such taking style in the Dewhurst Stakes, generally accepted as Europe's top race for juveniles, Frankel goes into the winter as a red-hot ante-post favourite for the 2,000 Guineas. And should he come through the close season unscathed, he will carry not only Tom Queally on his back as he canters to post for the Newmarket Classic, but the weight of hopes and expectations.

Sizing's stamina not at fault despite defeat, says De Bromhead

An experiment with the stamina of Sizing Europe appeared to backfire yesterday when he was turned over by one of just three rivals at Punchestown. But Henry de Bromhead, his trainer, was not immediately persuaded that the horse had failed to catch China Rock through lack of stamina.

Sizing Europe faces test of stamina in attempt to jump new boundaries

Though the Flat is yet to reach its final crescendo, with Champions' Day imminent and the Breeders' Cup still to come, what may prove one of the most significant experiments of the entire jumps season takes place at Punchestown today.

Case of St Nicholas Abbey haunts merchants of hype

Great things are expected from this season's youngsters, but recall what happened to O'Brien's 'star' of last year, says Chris McGrath

Team Godophin are once again gathering a rich autumn harvest

Hype about his rivals has rather distracted attention from Saamidd, but Saturday remains a momentous day for Godolphin. Their leading juvenile meets Frankel and Dream Ahead in the Jumeirah Dewhurst Stakes, while Poet's Voice tries to justify a gamble on his stamina in the Emirates Airline Champion Stakes. Godolphin certainly have a following wind, having celebrated a Group One double for the third consecutive weekend when Rio De La Plata and Biondetti won in Italy on Saturday. In the process, however, they compounded a growing suspicion that a trend has become a cycle.

Hughes refuses to concede title after appeal fails

There are no short cuts on the long and winding road to a jockeys' championship, and the one taken by Richard Hughes at the first bend at Wolverhampton last Saturday night now seems the most fatal of dead ends. Hughes yesterday took his six-day ban for careless riding to the British Horseracing Authority, and while its appeal board returned his deposit, he was otherwise sent away empty-handed. Bookmakers now make Paul Hanagan as short as 1-8 to win his first title.

Workforce may do overtime in US

Having seen the way things worked out on Sunday, nobody will mind in the slightest that connections of Workforce were yesterday once again reserving the right to a late decision on his next move. But the very fact that they are now contemplating a crack at the Breeders' Cup with their champion is sufficient to send an agonised frisson of hope and excitement down the spine of anyone who relishes the Turf's own Ryder Cup.

Workforce repays Stoute's faith to add Arc crown to his Derby victory

There were just inches in it at the line – une tête, to be precise – but the contrast with that seven-length annihilation of his rivals for the Derby in June was instructive of margins that are finer still. Workforce was only confirmed as an intended runner on Thursday morning, but the fact that he had finally satisfied a judgement as fastidious as that of Sir Michael Stoute should have told us all we needed to know. Yesterday, contesting the richest prize on the European Turf, Workforce vindicated his trainer in gripping fashion – and in the process redressed the most painful of the few remaining omissions in Stoute's CV.
