The Aidan O’Brien trained Treasure Beach won the featured MBNA Chester Vase at Chester this afternoon.
Ryan Moore has been partnering plenty of winners for the Ballydoyle stable this week and he took up the running a furlong out.
The pair looked set to win easily but Nathaniel battled on well under William Buick to get to within a head of the winner.
Moore said: “I had a nice spot round there. They went very steady early on and he travelled very well in behind them.
“When he got half a gap he quickened up very well and when he got to the front he probably eased up a bit.
“He’ll have to improve to be a Derby horse.”
The winner and runner-up are still available at 20-1 for the Investec Derby next month.
