(1) In a stake race, all horses duly nominated may enter.

(2) The maximum number of starters in any race shall be limited to the number of starting positions afforded by the association starting gate and its extensions. The number of starters may be further limited by the number of horses which, in the opinion of the stewards, can be afforded a safe, fair and equal start.

(3) A list of names not to exceed six may be drawn from the overflow entries in any purse race and listed as also eligible to start if originally carded horses are withdrawn. The order in which such horses are drawn will determine their eligibility to start. Their post position will be determined as provided by WAC 260-52-020. Any owner, trainer, or authorized agent having a horse so eligible and who does not wish to start, must file a scratch card not later than the scratch time designated for that day, or seek permission from the stewards to scratch as required by WAC 260-40-010.
