Adayar sprang a 16-1 surprise as he came home a wide-margin winner of the Cazoo Derby under a jubilant Adam Kirby at Epsom.
Trained by Charlie Appleby and only ridden by Kirby after he lost the ride on John Leeper to Frankie Dettori, the Godolphin-owned son of Frankel shot clear in the final furlong to give his handler a second win after Masar in 2018.
Richard Hannon’s Mojo Star, a 50-1 chance, ran a huge race to be four and a half lengths away in second, with the winner’s stablemate Hurricane Lane another three and a quarter lengths back in third.
Gear Up set the early gallop, with Kirby on his heels aboard Adayar and Youth Spirit also prominent in the early stages.
Favourite Bolshoi Ballet was also towards the head of the field, settled in fourth on the outside, while the well-fancied John Leeper was restrained in last place by Dettori until the field reached Tattenham Corner.
Gear Up started to drop away with two furlongs to run, allowing Kirby a run up the inside rail and he soon put daylight between himself and the field.
Mojo Star finished well from off the pace, with Hurricane Lane also keeping on at the one pace for minor honours, but Aidan O’Brien’s Bolshoi Ballet and the Ed Dunlop-trained John Leeper were both ultimately well-beaten.
