Tattersalls has increased the prize money for next year's Somerville Auction Stakes and October Auction Stakes to £200,000 apiece. The increase doubles the value of the Tattersalls Somerville Auction Stakes and is a £50,000 increase in the prize fund of the Tattersalls October Auction Stakes. Both races are open to any yearling offered at the Tattersalls Somerville Yearling Sale, the Tattersalls October Yearling Sale, Book 3 or the Tattersalls Autumn Yearling Sale, or for horses withdrawn from any of those sales and subsequently offered at the Tattersalls December Yearling Sale....
