A colt from the first crop of Desert Prince brought the top price of 52,000 guineas Thursday during the first session of Doncaster's breeze-up sale in England. Produced from the winning Sadler's Wells mare Lady Margot, the juvenile colt was consigned by Malcom Bastard, who purchased him for a price equivalent to just under 10,000 guineas at Goffs last October.The colt's buyer at Doncaster was Philip Johnston of McKeever St. Lawrence. The price was the highest for the auction since 1997. He told the Racing Post that the colt would go to Hong Kong and probably be trained by P.F. Yiu. The colt is from the family of Japanese champion Sakura Laurel.In all, 103 2-year-olds were sold for a gross of 1,268,380 guineas and an average of 12,314 guineas. The average was up by 18.6% over last year's first session figure of $10,386. The 105 horses sold in 2001 grossed 664,700 guineas.
