He was from the fourth crop of foals sired by Heart's Cry a horse whose wins included the Arima Kinen and the Dubai Sheema Classic.

[5] Christophe Lemaire took the ride when the colt started at odds of 12.7/1 for the Grade 3 Radio Nikkei Hai Nisai Stakes over 1200 metres at Hanshin on 21 December.

After racing in mid-division for most of the way he produced a strong late run to take the lead in the last 50 metres and won by one and a quarter lengths from Azuma Shuttle.

[6] In the official Japanese rankings for 2013, One And Only was rated the fourth-best juvenile colt (level with Isla Bonita), behind Asia Express Shonan Achieve and Win Full Bloom.

He was last of the eighteen runners for most of the way before finishing strongly to come home fourth behind Isla Bonita, To The World and Win Full Bloom, beaten less than two lengths by the winner.

[10] One And Only started favourite for the Kikuka Sho at Kyoto four weeks later but after racing on the outside for most of the way he was unable to make any progress in the straight and came home ninth behind Toho Jackal, beaten seven and a half lengths by the winner.

On his two remaining races of 2014 the colt was matched against top class older horses but made little impact as he ran seventh behind Epiphaneia in the Japan Cup on 30 November and thirteenth behind Gentildonna in the Arima Kinen on 28 December.

He produced one of his best performances as he took third place behind Dolniya and Flintshire with Designs On Rome, Just The Judge, Main Sequence and Harp Star running unplaced.
