In July 2015, he recorded his biggest victory in the King George VI & Queen Elizabeth Stakes at Ascot Racecourse and followed up with a success in the Prix Foy.
He was sired by Dubawi, a top-class son of Dubai Millennium, whose wins included the Irish 2,000 Guineas and the Prix Jacques Le Marois.
At stud, Dubawi has been a highly successful breeding stallion, siring major winners such as Monterosso, Al Kazeem, Makfi, Lucky Nine and Night of Thunder.
[4] He entered the ownership of Mohammed Obaid Al Maktoum (best known in racing circles as the owner of High-Rise) and was sent into training with Luca Cumani at Newmarket, Suffolk.
In August the colt started odds-on favourite for a similar event at Great Yarmouth Racecourse in which he was ridden by Kirsty Milczarek.
After being restrained by Atzeni in the early stages he struggled to obtain a clear run in the straight before staying on to take third place behind Cannock Chase and Mutakayyef.
A month later, Postponed was sent to Scotland for the Glasgow Stakes over eleven furlongs at Hamilton Park Racecourse and started 4/5 favourite against five opponents.
His opponents included Snow Sky (winner of the Lingfield Derby Trial and the Gordon Stakes), Hartnell (Queen's Vase) and the unbeaten Irish colt Granddukeoftuscany.
Ridden for the first time by Adam Kirby he started the 15/8 favourite, but after leading for most of the way he was overtaken and beaten three quarters of a length by the John Gosden-trained Western Hymn.
He led the field until the last hundred yards but was then overtaken and was beaten a neck and a short head into third by Al Kazeem and Fascinating Rock, with The Grey Gatsby in fourth.
John Gosden and Frankie Dettori, the trainer and jockey of Eagle Top, were highly critical of Kirby's tactics on Postponed.
[11] On 25 July, Postponed was one of seven horses to contest the 65th running of Britain's most prestigious weight-for-age race, the King George VI and Queen Elizabeth Stakes over 1+1⁄2 miles at Ascot.
Heavy rain on the day before the race led to soft ground which saw the withdrawal of several major contenders including Golden Horn and Flintshire.
[12] Snow Sky and Eagle Top were again in opposition, whilst the other runners were Clever Cookie (Ormonde Stakes), Madame Chiang (British Champions Fillies' and Mares' Stakes), Romsdal (third in the 2014 Epsom Derby) and the Italian challenger Dylan Mouth (Gran Premio del Jockey Club, Gran Premio di Milano).
Postponed stayed on well in the closing stages and prevailed by three quarters of a length from Spiritjim with Baino Hope taking third ahead of Dolniya.
[15] Postponed did not race for his new trainer until 6 March when he returned from a six-month absence to contest the Dubai City of Gold at Meydan Racecourse.
[18] On his return to Europe Postponed contested the Coronation Cup over 1+1⁄2 miles at Epsom and started odd-on favourite against seven opponents including the leading fillies Found, Simple Verse and Arabian Queen.
"[19] Postponed was made a strong ante-post for the 2016 King George VI and Queen Elizabeth Stakes but contracted a respiratory infection and was withdrawn three days before the race.
Atzeni tracked the leaders as the Varian stable's pacemaker King Bolete made the running before sending the favourite into the lead three furlongs out.
