Lloyd Williams buys into Cup runner

Irish horse Sir Isaac Newton will carry Lloyd Williams’ navy and white colours in the Caulfield Cup with the Australian businessman joining Coolmore in the ownership.

The Aidan O’Brien-trained five-year-old is on the fourth line of betting at $12 for Saturday’s $3 million handicap over 2400 metres.

Williams, his wife Susie and son Nick, are now partners with Sue Magnier and Michael Tabor in Sir Isaac Newton.
