He improved to become a top-class middle distance performer in the following year, winning the Gordon Stakes, Grand Prix de Paris and the Hong Kong Vase.
[3] She did better as a broodmare, producing several other winners including Secret Gesture (runner-up in the Epsom Oaks), Isaac Newton (International Stakes) and Mogul's full-brother Japan.
[4] Mogul was ridden by his trainer's son Donnacha O'Brien when he made his racecourse debut on 14 August in a maiden race over one mile at Gowran Park in which he started the 5/4 favourite and finished second to the Jim Bolger-trained Geometrical.
The colt was partnered by Ryan Moore when he recorded his first success in a similar event at the Curragh, leading from the start and coming home three and a quarter lengths clear of his eleven opponents at odds of 8/13.
He raced in fourth place as his stablemate Cormorant set the pace before moving up to take the lead a furlong and a half from the finish and kept on well to win by one and a quarter lengths from the second favourite Sinawann.
With Donnacha O'Brien in the saddle, Mogul started second favourite but despite racing making good progress from the rear of the field in the last quarter mile he came home fourth behind Kameko, Innisfree and Year of the Tiger.
Ridden by Moore he raced in mid-division before making steady progress in the straight but never looked likely to win and finished sixth behind his unfancied stablemate Serpentine beaten seven lengths by the winner.
[11] Mogul reappeared in the Great Voltigeur Stakes at York Racecourse on 19 August and started favourite but after being contention for most of the way he was beaten into third place behind Pyledriver and Highland Chief.
Mogul raced towards the rear of the field as his stablemate Nobel Prize set the pace but made rapid progress along the inside rail in the straight before being switched left and taking the lead 300 metres from the finish.
Starting the third choice in the betting he produced a sustained run from the rear of the field but never looked likely to win and came home fifth behind Tarnawa, Magical, Channel Maker and Lord North, beaten three lengths by the winner.
