Frankel's scintillating performance in the Juddmonte Royal Lodge Stakes is rated the best in the Ascot contest for 20 years.
The Henry Cecil-trained youngster has earned an official rating of 123 thanks to his 10-length victory in the Group Two contest over a mile on Saturday.
Matthew Tester, British Horseracing Authority handicapper for two-year-olds, said: "It was impossible not to be impressed with the style of Frankel's win at Ascot on Saturday when landing the Royal Lodge by 10 lengths.
"Whilst it is true that none of his opponents were likely to test a champion, the manner of his run and the huge winning margin has landed him an official rating of 123.
"This is easily the best Royal Lodge performance of the last 20 years and puts him well ahead of horses like Benny The Dip (113) and Mister Baileys (115), who won the race before success in the Derby and the 2000 Guineas respectively the next year.
"Eltish at 118 is the next highest winner for this race and he went on to run second in the Breeders' Cup Juvenile back in 1994.
"I can't wait to see Frankel take on stronger opposition next time in the Dewhurst Stakes.
"In the last 10 years the highest-rated two-year-olds have been Johannesburg and New Approach, each of whom reached 126.
"It is 16 years since Celtic Swing was credited with 130 for crushing his Racing Post Trophy opposition, nd it will be exciting to see if Frankel can hit those heights," Tester told
