Curiously, Frankel appears doomed not to produce a son or daughter who is superior to him. The Racing Post’s bloodstock expert, Tony Morris, writes: “No horse rated 138 has ever sired a horse rated 138 or above. Frankel may well get plenty of good runners, and I hope he does, but I can guarantee he will never sire his equal; he is the ceiling, and regression to the mean dictates that all his stock will be inferior to him.”
This is probably also true of Beyer speed figures. Has a horse who has peaked at 120 or above ever sired an equal? Ghostzapper topped out at 128 (in the 2004 Iselin Handicap at Monmouth Park); Contested and Hunters Bay, two of his best progeny, certainly haven’t come close to such a number.
