2.30 at Westminster: The Berkshire Hunt

Runners
1. The Dirty Digger.
An old nag with plenty of form.
2. Jimmy the Peanut.
Sired by the Dirty Digger but claimed by some in the stables to be flawed.
3. Rebbe the Red.
A chestnut filly with staying power and a mean streak. Bad for riders and other nags.
