TDN Sire Lists were born of a desire to create sire lists of relevance to the international commercial thoroughbred marketplace. All TDN Sire Lists conform to Black Type Rules, which means that the information you'll find here is the same information you'll find when you open a catalogue on the sales grounds. And because we know that everyone likes looks to look at information in their own way, we have made these lists sortable by any of the categories presented--by the top 100 sires, or by all sires. We think you will find them a handy and relevant tool in your thoroughbred research.

TDN Sire Lists include earnings worldwide by foals from Northern Hemisphere-sired crops, excluding Japan. Wins, black type wins, starters, and all other criteria earned in Japan is counted in the totals; only their earnings are excluded. All sires on these lists have had a foal running in the Northern Hemisphere in the past 360 days. Black type is as designated in the International Cataloguing Standards in association with the International Federation of Horseracing Authorities and approved by the Society of International Thoroughbred Auctioneers (SITA). That is to say the information you see here as far as what is a Black Type race, and what is a Graded or Group Black Type race is the same information you'll find when you open a catalogue on the sales grounds.

Year-to-Date Lists' are calculated on a percentage to runners (e.g. Black Type Winners / Runners) while Cumulative Lists' percentages are calculated with named foals (e.g. Black Type Winners / Named Foals).
