The colt from Santa Rocks went to Hawkes Racing who secured the prized youngster from the Arrowfield Stud draft.
The $850,000 sale price is the highest ever for the yearling section of the Magic Millions National Sale beating the previous record of $500,000 that was equalled on the first day of this year’s sale.
"When you come to Magic Millions you have to pay for them - they don't give them out at the front door,” said co-trainer Wayne Hawkes.
"We really liked him. We think he will be a real classic three-year-old type horse and we thought he was the best Dundeel of the year so we made sure we got him.
"You know when you break a record it's dear. If he's a good horse he will be cheap - it's as simple as that."
Three of the top four sellers on Day 2 were presented by Arrowfield Stud including a Not A Single Doubt brother to Stronger sold to Muskoka Farms for $430,000.
Catalogued as Lot 2303, the bay colt is the third foal of the winning Starcraft mare Star Pupil - a mare who has produced two winners and both stakes performers.
The colt's full brother Stronger is a high class two-year-old who at his most recent start won the G3 Ken Russell Memorial Classic at the Gold Coast. He is currently spelling for the Snowden stable.
The other $430,000 seller on the day produced another record when the Rich Enuff-Tanzanite colt sold to George Moore Bloodstock, making him the highest price ever for Woodside Park Stud's young sire Rich Enuff.
The result was an emotional one for the team from Fernrigg Farm including Rae-Louise Farmer who foaled down the colt and prepared him for a good client and friend.
“He was the first foal born on Fernrigg," Farmer said. "He had a bit of a setback earlier on and missed another sale. I was so happy when asked if we would prepare him for this sale.
"We loved him from the day he was born. He was the first horse I foaled on my own.”
The sale gross for the National Yearling Sale at the conclusion of Book One passed $12.5 million - well up on last year's $9.9 million.
The average price was up to $52,556, and the clearance rate is just shy of 70 per cent.
"I'm really pleased," Magic Millions managing director Barry Bowditch said.
"The clearance rate is obviously a little bit disappointing but the average has climbed from $43,000 to $52,000 - that's a considerable increase.
