Workforce gave Sir Michael Stoute his fifth success in the Investec Derby at Epsom with a brilliant performance under Ryan Moore.
A 6-1 chance having finished second in the Dante Stakes at York, the King's Best colt was settled towards the rear by the champion jockey as Ballydoyle pacemaker At First Sight set a scorching gallop.
The latter held a huge lead turning for home, but Workforce mowed him down halfway up the straight and galloped all the way to the line to score by seven lengths in a record time.
At First Sight, sent off at 100-1, ran an incredible race to fill the runner-up spot, while Rewilding was third for Frankie Dettori.
It was a first success in the race for Moore - and the second leg of an amazing double after he secured his first Classic victory on Snow Fairy in Friday's Oaks.
Stoute, who had registered previous Derby wins with Shergar (1981), Shahrastani (1986), Kris Kin (2003) and North Light (2004), has never made any secret of the regard in which he holds Workforce.
He arrived at Epsom on the back of just two starts, an impressive debut win at Goodwood as a juvenile and his second to Cape Blanco on the Knavesmire.
Aidan O'Brien's Jan Vermeer was sent off the hot favourite under Johnny Murtagh but could only finish fourth.
