He was a star juvenile performer that was rated the best colt of his generation

In just nine starts over 11 months The Autumn Sun rocketed to stardom with an escalating series of championship victories that rank him with Australia’s best colts of the past quarter-century, including his own legendary sire, Redoute’s Choice. Eleven months later The Autumn Sun was the head of his generation, winner of $3.4 million and 5 Group 1 races from 1400 to 2000m in 9 starts, and the only horse to win the three major Australian Guineas races at Caulfield, Randwick and Rosehill.

The Autumn Sun (foaled 2 September 2015) was trained and bred in Australia out of the mare Azmiyna (Galileo). The colt was purchased for $650,000 at the 2016 Inglis Easter Yearling Sale. Olly Koolman of Hermitage went with the plan to buy a Derby winner. Guy Mulcaster identified him and had him on a shortlist. He was one of the first through the ring on that list and they bought confidently with him. From December 2017, The Autumn Sun had 4 trials before he made his debut at Royal Randwick on 25 April 2018. Trapped 3 wide, he took the lead with 100 metres left in an "eye-catching debut". A month later, he won his second race at Randwick, where the further the race went the more decisive and dominant he became. In June, the colt won The J. J. Atkins, coming from 6 lengths back to win. Trainer Chris Waller said was questioning whether at only his third start, like State of Origin, only certain people and horses can take those steps.

After three months spell, The Autumn Sun had two Sydney trials in August 2018. Next was the Gr.2 Stan Fox Stakes, where he failed to win for the first time. In a "horror story", he was trapped on the rail and blocked for a run, eventually finishing third. Jockey Kerrin McEvoy considered protesting against the winner for interference. Waller knew the horse was very unlucky, however, a fortnight later, The Autumn Sun won his second Group 1, the Golden Rose Stakes. McEvoy was a bit worried when he got to the outside at 350m and still last, but in 10 strides he knew the colt was the winner. The prospect of extending the horse's distance to 2000 metres was already thrilling, given its demonstrated late-race power and exceptional strength at shorter distances. The Sydney Morning Herald described him as, "already the best colt of his generation". A further Group 1 was won two weeks later in the Caulfield Guineas. Jumping as $1.70 favourite, he settled in a poor position, but romped away to win in stunning fashion to win by four and a half lengths. Jockey James Mcdonald rode him near the lead for the first time in his career and the colt was dominant again.

Spelled for 4 months, The Autumn Sun returned in the Gr.2 Hobartville Stakes in February 2019. The Autumn Sun's much-anticipated return has followed the script at Rosehill. The nation's most valuable colt came from last to win, overhauling previously unbeaten Vegadaze by a long neck. On 9 March in the Randwick Guineas against a field of 9 including Nakeeta Jane (winner of the 2019 Surround Stakes and 2019 Light Fingers Stakes) and Miss Fabulass (2018 Tea Rose Stakes) he was about 10 lengths off Miss Fabulass passing the 400m mark. The Autumn Sun was always getting closer to the leader through the straight and at the post The Autumn Sun crossed first winning by a head to Fundamentalist. He also equalled the race record of Kementari who won in 2018 with a time of 1:33.72 which gave him his 4th Group One race and 4th consecutive win since his 3rd in the Stan Fox Stakes. This horse has exceptional ability and that has allowed him to win 5 x G1 races at this very early age and in an immature state.

Waller has publicly stated he wanted to train The Autumn Sun as a four-year-old and outlined his reasons to the ownership group. The decision to retire the colt was likely influenced by the death in March 2019 of The Autumn Sun’s champion sire Redoute’s Choice at Arrowfield aged 22. The Autumn Sun became the seventh son of Redoute's Choice to stand at the iconic Hunter Valley stud. He entered the market as one of the highest priced first-season sires in Australian thoroughbred history, ($77,000) $20,000 more than the two highest-priced debutant stallions of last season, Merchant Navy and Russian Revolution stood for in their first seasons in 2018.

He has wasted no time justifying their belief in him. His first crop includes 8 stakes performers: dual Group winners Autumn Angel & Autumn Ballet, Group 3 winner Vibrant Sun, Listed winner Coco Sun, Group 1-placed Tulsi & Tutta La Vita and stakes-placed Kosgei & The Autumn Belle, as well as promising winners Colours of Autumn, Harvest Moon, Know Thyself, Private Legacy, Slinky & Sunlord. Buyers responded in 2022 & 2023 with more than $36 million for The Autumn Sun’s yearlings, including the 2023 $1.8 million Inglis Easter sale-topper and another $1.2 million filly. His 16 yearlings sold at Inglis Easter in 2024 averaged $246,000.
