In claiming races any horse may be claimed for its entered price by any owner presently registered in good faith for racing at that meeting, who has nominated a starter up to or including the race in which the claim is made or by his authorized agent, but for the account only of the owner making the claim, or for which the claim was made by the agent; provided, however, that no person shall claim his own horse or cause his horse to be claimed directly or indirectly for his own account.
