Stradivarius enjoyed his 20th career success and picked up a perfect six from six York races with a victory at the Paddy Power Yorkshire Cup under the leadership of Frankie Dettori.
It was a record-breaking performance from eight-year-old Bjorn Nielsen, who made a sweet move forward before finding enough final points to win his 18th European group stage race.
All of the trained John and Thady Gosden soon finished fourth behind Thunderous and Franny Norton.
As the speed increased, Stradivarius quickly hit a flat spot but was soon back on the reins and Dettori helped him easily overcome the gap between the leader and Max Vega with three feathered tongs to run. .
He achieved his highest stride with a quarter of a mile left to go, but the 6-4 favorite was out of action once hitting the front as he drifted to the grandstand rails and had to dig deep as the Thunderous fight back.
However, he has had a long time to come in through an illustrious 17-2 runner-up and will now head for Royal Ascot in a bid to claim his fourth Gold Cup, for which he was beaten by Betfair down to 3-1.
