Bookmakers were struggling to contain their delight after Adayar stormed to Cazoo Derby success at Epsom.

Aidan O’Brien’s Bolshoi Ballet was sent off the red-hot 11-8 favourite and although seemingly in the ideal position approaching the business end of the mile-and-a-half showpiece, he could only manage a well-beaten seventh under Ryan Moore.

Others fancied contenders that failed to make an impact were Irish 2,000 Guineas winner Mac Swiney and John Leeper, the mount of Frankie Dettori.

Adding further joy for the layers was 50-1 chance Mojo Star finishing second to the 16-1 winner.

Coral’s David Stevens said: “The Derby is always the biggest betting race of the Flat season, and going into this year’s renewal, two horses emerged as the most popular with punters, favourite Bolshoi Ballet and Frankie Dettori’s mount, John Leeper.

“But neither could land a blow once the stalls opened, and although Adayar attracted some late support, his victory was still very much in our favour.”

For Ladbrokes, Nicola McGeady said: “Adam Kirby is the toast of Ladbrokes this afternoon after landing the Derby on Adayar. Every horse in this year’s renewal attracted support at some stage, but Adayar was the best result in the book.”

Paddy Power spokesman Paul Binfield added: “The winner didn’t go unsupported each-way at fancy prices, but despite that and Mac Swiney finishing fourth not being ideal with our extra place, it was still a good result for us.”

Looking to the future, Coral make Adayar the 4-1 favourite for the St Leger, while Ladbrokes quote the son of Frankel at 8-1 for the Prix de l’Arc de Triomphe.
