Snow Sky was an impressive winner of the betfred.com Derby Trial Stakes at Lingfield on Saturday.
Sir Michael Stoute's Nayef colt paid a huge compliment to Newbury conqueror Western Hymn when winning at Lingfield by a comfotable two lengths.
Jim Crowley picked up the spare ride due to James Doyle's absence through injury and he had an easy day's work as Snow Sky travelled well throughout before effectively putting the race to bed two furlongs out.
Hartnell and Sudden Wonder stayed on well down the outside to fill the places but they were never going to reach the winner, who was cut to 20/1 from 50s in Sky Bet's Derby market.
Western Hymn was trimmed to 10/1 from 12s on the back of the form boost.
Crowley said: "I've never sat on the horse but I have seen him before.
"He wasn't doing an awful lot in front and I was impressed with him.
"He was in front two and a half down and he could have done with a bit of company.
"It's up to connections (if he goes to Epsom) but he's a classy horse and he went round here so Epsom wouldn't be a problem."
Stoute said: "We're very pleased with that. He ran a very nice race initially at Newbury and he's progressed since.
"We knew the extra distance would suit him and he handled the track well and couldn't have done it more nicely. He's got a great mind.
"Teddy (Grimthorpe, racing manager for owner Khalid Abdullah) has to speak to the Prince, but I'd like to see the Dante (at York next week) before committing him (to the Derby).
"I wouldn't want to jump in now and say he definitely goes for Epsom.
"It does encourage you, but we'll sit tight. He's got the balance, he will handle the track and he's got a great temperament, but I wouldn't like to tell punters to back him (for the Derby) today.
"He ticks all the boxes bar that one."
Sky Bet's Michael Shinners said: "Snow Sky did that nicely but his performance was equally significant for Western Hymn fans and we trimmed the John Gosden-trained horse on the back of the Lingfield race."
