The young Dubawi colt, out of Dar Re Mi, pulled seven lengths clear in a one-mile maiden as the 8-11 favourite – much to the satisfaction of Frankie Dettori.
“Any horse winning by seven lengths first time, you’ve got to take notice,” said the jockey.
“He hit a couple of green spots but when I asked him to quicken on ground that is quite tiring, he put himself quite a long distance from the rest.”
Trainer John Gosden was similarly impressed with Too Darn Hot, owned and bred by Lord Lloyd-Webber.
The Clarehaven handler told Racing UK: “He’s a charming horse.
“There was a nice ease in the ground and he enjoyed it. He’ll have learned a lot.
“He’ll go for a novice next and then we’ll see from there.
“He’s a grand colt and hopefully he’s got a good future.”
Too Darn Hot, who holds an entry in the Champagne Stakes at Doncaster next month, is as low as 12-1 with Paddy Power about winning next season’s Guineas. He is available at 14s with the same firm for the Derby.
