Further controversy surrounds the sale of horses from Patinack Farm with auctioneer Magic Millions withdrawing 13 horses from Friday's sale.

Owner Nathan Tinkler put all his stock, excluding stallions, in a supposedly unreserved sale at the Magic Millions but withdrew 22 racehorses on Wednesday, some of which are racing at Eagle Farm on Saturday.

Patinack has also bought back some of the horses over the course of the saleat the .

Magic Millions withdrew another 13 horses from Friday's sale saying it was protecting buyers.

"The vendor (Patinack Farm) was expecting more money than a fair market was prepared to pay," managing director Vin Cox said.

"As he was going to be bidding on these lots we decided to exercise our right to take them out to keep the integrity of the sale and protect buyers."

The highest-priced lot on Friday was knocked down to Patinack Farm trainer John Thompson.

Thompson was the successful bidder when Another Prayer, an unraced two-year-old filly by Encosta De Lago out of the Australian Oaks winner Heavenly Glow, went through the ring for $140,000.

In April, Patinack Farm was put up for sale on a walk in-walk out basis but no deal has been struck.

According to a Patinack Farm statement, the horses it withdrew from Friday's sale session are on the market privately.

It said the company was genuine in offering its entire operation for sale and the dispersal of 400 horses had signalled its intention to sell bloodstock at the Magic Millions sale.

"However some yearlings and racehorses have been retained to assist with negotiations for the broader sale of the business," the embattled thoroughbred company said.
