Planet Sport tipped up Nahanni at Epsom on Tuesday, April 19 and the Godolphin colt did the business for Charlie Appleby.
The three-year-old son of Frankel took the Cazoo Blue Riband Trial at Epsom in gritty style and now has an entry to the Cazoo Epsom Derby in June.
Jockey Will Buick survived pressure from Charlie Fellowes' Grand Alliance to win by half a length on the Epsom downs.
Zain Sarinda was a neck back from Grand Alliance in third.
The winner for the boys in blue went off the 9-4 favourite and the Trial success means a place at the Epsom Derby is available should connections choose to run.
With trainer Charlie Appleby absent, assistant trainer Alex Merriam said: "He has had four runs this season, so we will probably put him away now and hopefully come back for the Derby.
"I say definitely, but we are a long way out. He gets the entry for winning that, but there is a lot of water to be crossed between now and then, but that will be the plan.
"We have a few other irons in the fire and we will have to see how they play out in the next few weeks, but that will be the plan."
Nahanni had won in eye-catching fashion at Leicester 18 days ago and had cheekpieces applied this time around.
"He did plenty in the blinkers last time and we just thought the cheekpieces should be tried this time," said Merriam.
"It is lovely. We are in a very spoilt position as Sheikh Mohammed has some lovely horses to train, so we are very fortunate."
Buick added: "It was a nice performance and he came on again. We were back in trip from Leicester but that was not really a concern. He got on the front and he is very comfortable up there.
"I liked his performance - he saw them all off and handled the track, which is obviously key, so he is a horse who stays very well as well.
"Every time they came to him, he went again. At the top of the straight, I thought it would be me and Frankie (Dettori, aboard Mighty Ulysses) and then obviously he had to fight all the others off after that.
"He handled the track and this was the most competitive race he has faced, so he has learned plenty."
