All other 3yos end 3/5 for Pool 1.
Smile Happy with his dominant win in the KY Jockey Club Stakes at Churchill Downs , as well as a $10,000 bet from Mattress Mack, closes as the non-entry favorite at 8-1.
Smile Happys pedigree doesn't scream a mile and a quarter in May, but from his two races so far, it looks like he can run all day.
