The forecast for Saturday’s Kentucky Derby includes a chance of rain, which should impact your betting strategy.

Sandman and Baeza are the only horses that cost more than $1 million, but four others cost at least $600,000. Chunk of Gold is the rare Derby horse purchased for just four figures, but three others in the field went for less than $100,000. There are also five homebreds in the field, meaning they were also bred by their current owners.
