Time has run out for an autumn racing campaign for the brilliant Kingman and it was announced during the week that the multiple Group 1 winning son of Invincible Spirit has been retired and will stand at Banstead Manor Stud in 2015 alongside Frankel. A fee has yet to be announced.

Described as the best colt he had ever trained by John Gosden, the Juddmonte homebred won seven of his eight career starts, highlighted by victories in the Irish 2000 Guineas, the Prix Jacques Le Marois, Sussex Stakes and St James’s Palace Stakes. His only defeat came in the 2000 Guineas at Newmarket. He also scored group race successes in the Solario Stakes as a juvenile and the Greenham Stakes this year. He amassed earnings of more than £970,000.

The announcement of his retirement was made by Lord Grimthorpe, racing manager to Khalid Abdullah, and he said that the colt is continuing to receive treatment for a throat infection that had cast a doubt on his autumn racing programme. This meant he would be unable to take up his planned engagement in the Queen Elizabeth II Stakes or a possible tilt at the Breeders’ Cup.

Gosden was fulsome in his praise for Kingman. “He’s a fabulous-looking horse with a great mind on him and he had the ability to change six gears at once. He had a turbo charge that no other horse I’ve trained has possessed. It’s a very rare thing to see in a horse.”

Irish racegoers saw the colt cruise to a five-length victory in the first classic of the year here, but it was his performances in the St James’s Palace Stakes and the Sussex Stakes that stamped him as a colt of exceptional talent. At Royal Ascot he avenged his sole defeat by Night Of Thunder in the 2000 Guineas.

Kingman has an outstanding stallion’s pedigree. He is a half-brother to group-winner Remote and they are out of the classic winning Zamindar mare Zenda.

Stud plans were also announced this week for Toronado, runner-up to Kingman in the Sussex Stakes at Goodwood.

He will continue to race until the end of the season and the Queen Elizabeth II Stakes is a likely target. The son of High Chaparral will take up stud duties next season at the National Stud in Newmarket.

An unbeaten Group 2 winner as a juvenile, Toronado avenged a short head defeat by Dawn Approach in the St James’s Palace Stakes with victory in the Sussex Stakes last season. He added another Group 1 win to his roll of honour when he captured the Queen Anne Stakes at Royal Ascot this year.

John Warren will manage Toronado at stud and his son Jake will be in charge of nomination sales. A fee has yet to be announced.
