Arkansas Derby
In 2004, to celebrate its 100th anniversary, Oaklawn Park offered a $5 million bonus to any horse that could sweep its three-year-old graded stakes, the Rebel Stakes and the Arkansas Derby, and then take the Kentucky Derby. Smarty Jones's collected the bonus. The exposure from Smarty Jones subsequent run at the Triple Crown helped increase participation from the top three-year-olds in the country to the point where the American Graded Stakes Committee made the Arkansas Derby a Grade I race in 2010.
