In 2012 he was sent to England and put up for the auction at the Tattersalls October Yearling Sale where he was bought for 200,000 guineas by the bloodstock agent John Warren on behalf of the Coolmore Stud.
As a breeding stallion he was not a conspicuous success and was eventually exported to Russia, but he did sire several other good winners including George Vancouver (Breeders' Cup Juvenile Turf) and Pedro the Great.
[5] Sudirman made his debut in a minor race over six furlongs at Naas Racecourse on 15 May in which he started at odds of 10/1 and finished last of the five runners behind Big Time.
Eleven days later, in a maiden race at the Curragh he produced a much better effort as he came home in third place, beaten a length by the Aidan O'Brien-trained winner Sir John Hawkins.
On 20 June at Leopardstown the colt started odds-on favourite for a maiden and recorded his first success as he took the lead a furlong out and pulled away to win "comfortably" by four and a half lengths from nine opponents.
[6] Nine days after his win at Leopardstown the colt was stepped up in class and started 5/1 third favourite in a five-runner field for the Group 2 Railway Stakes at the Curragh.
Carrying a five pound weight penalty for his Group 1 success he chased the leaders before dropping away quickly and being eased down by Lee in the closing stages to finish 20th of the 23 runners.
