The Autumn Sun (foaled 2 September 2015) was a Thoroughbred racehorse trained and bred in Australia. He won five Group One races and over three million dollars. Career The Autumn Sun was purchased for $650,000 at the 2016 Inglis Easter Yearling Sale. Olly Koolman of Hermitage said, "We 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 we 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 it was said, "the further the race went the more decisive and dominant he became." On 9 June, The Autumn Sun won The J. J. Atkins, coming from 6 lengths back to win. Trainer Chris Waller said, "I was questioning whether at only his third start, like State of Origin, only certain people and horses can take those steps. We just said if things work out and if he’s as good as we think he is, he could win the J.J. Atkins." After three months spell, The Autumn Sun had two Sydney trials in August 2018. Next was the Group 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 said, "He was very unlucky, we will leave it at that." A fortnight later, The Autumn Sun won his second Group 1, the Golden Rose Stakes. McEvoy said, "I was bit worried when I got to the outside at 350m. I was still last then, but in 10 strides I knew he was the winner. To be doing that to a very good group of colts at what I consider his minimum distance is amazing. Wait until he gets to a mile and 2000m – he is going to get much better." 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
