Timeform have rated Frankel at 143, the highest figure awarded to any horse since 1972 and the fourth-highest in the company’s history.
Timeform’s Simon Rowlands said: “1972 was the year in which Brigadier Gerard posted 144. Sea-Bird (145 in 1965) and Tudor Minstrel (144 in 1947) are the only other horses to have been rated more highly than Frankel in Timeform’s long history.
“Frankel is a remarkable 8 lb clear of the next-highest horse, Black Caviar, and 10 lb ahead of the next-highest in the Northern Hemisphere, margins unprecedented in recent times.
“The Sir Henry Cecil-trained colt is unbeaten in nine starts, including the Two Thousand Guineas, the Sussex Stakes and the Queen Elizabeth II Stakes in the latest year.
“Any of those successes would have qualified Frankel for Horse of The Year status. Timeform rated him 142 after the first of those wins and edged him up to his current figure after the Queen Elizabeth.
“Next in is the unbeaten Australian-trained mare Black Caviar on 135, only 1 lb behind the best fillies/mares in Timeform’s experience.”
