Group 1-winning daughter of The Autumn Sun sells for $1,225,000.

Less than a week after learning about the injured that ended her racing career, Wylie Dalziel and the team associated with Autumn Angel have farewelled the mare who has become Inglis Digital's latest seven-figure product.

This year's ATC Australian Oaks winner, who was the subject of a standalone sale early this week, sold for $1,225,000.

Walnut Farm, an associate of growing giant Yulong, ended with the winning bid for the four-year-old daughter of The Autumn Sun.

The sale was a quick turnaround and Dalziel said while a good result for the filly they bought for $230,000 at Inglis Easter, it was a bittersweet situation.

"The ownership group are rapt with the result, although understandably we didn't envisage selling her so soon," Dalziel said.

"This time last week we were disappointed and in shock when we received the news from the stable about her injury.

"But as the manager I had to move quickly, and I must thank Sebastian (Hutch), James (Price) and the team at Inglis for facilitating such a quick turnaround.

"There are nine owners including some long-time clients and they all were quick to back the decision to offer her as a breeding prospect and she was put in front of all the right people with Inglis Digital."

The ATC Oaks was the biggest of Autumn Angel's four wins, for Peter Moody and Katherine Coleman, having also placed five times for prizemoney of just under $1.2m.

Having secured Autumn Angel, attention now turns to working out what happens with the mare with one of Yulong's growing suite of stallions to be chosen as a first mate.

"She has a great pedigree and by a stallion that is well on his way as a highly commercial stallion of the future," Vin Cox said.

"No plans as to her future at this early stage, we will get her home and into the system."
