Stradivarius claimed his 17th Group victory - and second Doncaster Cup - with a smooth success under Frankie Dettori.
The jockey spent much of the home straight looking over his shoulder for non-existant dangers before finally asking him to claim the hard-ridden leaders.
He did so passing the two furlong marker and was merely kept up to his work to beat Alerta Roja by two-and-a-half lengths.
The 4/11 favourite was providing John and Thady Gosden with their 100th winner of the year.

Gosden said: “He’s a wonderful horse. He’s been great at home. He’s enjoyed all his training. He loves his racing and likes coming racing. He’s a phenomenon. I had no qualms about coming here. He senses a horse coming to him and plays cat and mouse with them now.
“I couldn’t have been more thrilled with him. I’m sorry the other horse (Trueshan) didn’t run but maybe we’ll meet one day. He’s had a great season. He’s won three out of four. Frankie’s ride in the Gold Cup wasn’t his greatest. The winner was mighty impressive and the sad thing for me in the year is that we couldn’t run at Goodwood, because he adores Goodwood.
“His enthusiasm is there 100 per cent and I can assure everyone who loves him, the moment it’s not there he will be retired. Until that day comes, which he will tell us, he will race.”
Gosden is now considering the autumn options in France and Britain for Stradivarius.
He said: “There are two races in the autumn – the Cadran and Ascot (Qipco British Champions Long Distance Cup). Ascot last year was heavy and he hated it. Those are the options. It will be one not both.
“He’ll go on summer soft but not when it goes autumn deep. He cannot take it. It was a mistake to run him in it last year and in the Arc. He lives a bit on the edge. He lets us know what he wants. I’ve always adored stayers and to train him is a dream come true.”
Dettori added: “That was great. It’s probably the easiest race he’s had since last time he was here. He made it look easy again. He still loves his racing."
