Ruler of them all at Epsom

Ruler Of The World provided Aidan O’Brien with a fourth Investec Derby and maintained his unbeaten record under Ryan Moore at Epsom – with favourite Dawn Approach well beaten.

Dawn Approach failed to settle from very early on and Kevin Manning felt he had no option but to take up the running on the approach to Tattenham Corner, with the writing being on the wall some way out.

Ruler Of The World (7-1) showed a smart turn of foot to go clear, but Battle Of Marengo, Galileo Rock and Ocovango all set off in pursuit.

The gap was closing at the line as Libertarian flashed home to claim second with Galileo Rock in third.

In the early stages Joseph O'Brien on Battle Of Marengo set a pedestrian gallop and with Dawn Approach wide with no cover and still pulling, Manning was forced to play his hand early.

Moore had the eventual winner just on the outside of Ocovango as the pace quickened and the French raider had to take a pull, forfeiting valuable ground.

Galileo Rock was handy throughout and stuck to his task gamely, outrunning his big price, but arguably the horse to take from the race was the unheralded runner-up, who was catching the winner with every stride, going down by a length and a half.

Battle Of Marengo was fourth, but Dawn Approach was eased markedly, beating just one home.
