LONDON (AP) — The first foal fathered by Frankel, widely regarded one of the world's greatest racehorses, is going up for auction.

Crystal Gaze, a mare with an impressive breeding pedigree herself, gave birth to the colt on March 18 and is also up for sale.

Both are expected to sell for more than 1 million pounds ($1.68 million) at Monday's auction at Kensington Palace. The mare is expecting her second foal from Frankel early next year.

Frankel was retired to stud in October 2012 after winning all 14 of his races. He mated with 133 mares from February to June last year at 125,000 pounds ($200,000) a time.

The manager of Frankel's stud farm, David Redvers, says the colt "has what I would call a typical Frankel temperament in that he knows he is special and really owns the show."
