Sir Isaac Newton went some way to redeeming his lofty reputation in the Irish Stallion Farms EBF Maiden at Gowran Park.
Fancied for the Classics after making leading Investec Derby contender Zawraq pull out all the stops on his only appearance as a juvenile, Aidan O'Brien's expensive Galileo colt blotted his copybook on his Chester comeback.
Sent off the 4-6 favourite to atone, Seamie Heffernan's mount took the lead off chief market rival Valac approaching the furlong marker.
He quickened smartly and despite showing some signs of inexperience still, coasted past the post three and a quarter lengths ahead of Stop And Linger.
Heffernan said: "He's one that we have always liked and that was expected. I expect more progress.
"A mile and a quarter might end up being his ideal trip."
