The Lion In Winter roared loudest at York to come out on top in a Tattersalls Acomb Stakes showdown with Ruling Court.

The duo were dominating the top of the markets for next year’s Classics having both impressed in their respective debuts and a change in race conditions saw the stellar two-year-olds lock horns on the Knavesmire on just their second career outings.

Charlie Appleby’s son of Justify was billed as the star attraction following his spectacular display at Sandown and was settled in mid-division by William Buick, as Ryan Moore aboard The Lion In Winter was at the head of proceedings alongside Hugo Palmer’s The Waco Kid.

Buick asked the even money favourite to move into contention as the race entered the final quarter mile but there was no way past Aidan O’Brien’s son of Sea The Stars, who grew stronger the further he went.

The Lion In Winter came home with a length and three-quarters advantage as the 2/1 second favourite, with Ruling Court eventually giving way to Wimbledon Hawkeye for second, James Owen’s colt outrunning odds of 22/1.

The winner was made 8/1 favourite for next year’s 2000 Guineas with Paddy Power, with the firm also making him the 6/1 market leader for the Derby.
