Too Darn Hot ran out an impressive winner of the Howcroft Industrial Supplies Champagne Stakes at Doncaster.
The son of Dubawi was stretching his unbeaten record to three in his toughest test so far and sat off a frantic early pace set by Cardini and Bye Bye Hong Kong.
Frankie Dettori made his move two out aboard the 4/11 favourite, who quickly went to the front and stretched clear to beat Acomb winner Phoenix Of Spain by a length-and-three-quarters.
Disappointment of the race was Dark Vision, who never looked happy under Silvestre de Sousa and finished last.
Racing PR Manager Michael Shinners said: "He's really emerged as the leading juvenile colt in England over his last two starts and this was a very impressive performance. He already looks a serious 2000 Guineas contender."
Gosden said: "He was very impressive and it took Frankie a long time to pull him up. He and Seamie went past the Leger start and up to Rose Hill.
"It's a long way to gallop out after a seven-furlong two-year-old race. Maybe they were trying to find out if they'll stay middle-distances next year!
"I'm happy with him and he did everything right. He quickened up from a long way back - he's a young, talented horse. He's in the three Group Ones in October and there'll be no decision (on which one he runs in) for 10 days."
Dettori added: "That was very special. What he did between the three and the one blew me away. I guess the next step is a Group One, but he is very talented. When you run him on a flat track you can really feel his gears. He's learning how to race and everything he did today was amazing."
Asked whether he felt Too Darn Hot was a Guineas or Derby horse, Dettori added: "We'll take it one step at a time. We're only learning about him."
