Beaten out of sight in the 2,000 Guineas, Auguste Rodin repaid O’Brien’s faith by running down outsider King Of Steel in the final furlong.
It wasn’t to be for Frankie Dettori on his final ride in the Derby, as 4-1 favourite Arrest failed to fire and finished well beaten in tenth.
King Of Steel looked set to cause a 66-1 shock when he shot clear at the top of the hill on his first start of the year.
Moore, in classic fashion, didn’t panic and slowly reeled in Kevin Stott, getting up in the dying strides at 9-2.
White Birch was last at the top of the hill and did extremely well to finish third for John Murphy and Colin Keane, who was having his first ride in the race.
Sprewell was looking to give Jessie Harrington a fairytale success in the race but after failing to handle Epsom, he could only finish fourth.
It was Moore’s first Derby since Rule The World scored in 2013 and was his third in total.
For O’Brien, it was business as usual in Britain’s biggest Classic, winning a record extending tenth Derby.
Remarkably, the master of Ballydoyle has won seven of the last 12 Derby’s.
