The Runhappy Hopeful Stakes on Labor Day is the traditional closing-day feature of Saratoga Race Course’s elite summer meet and often is a showcase of rising stars who will play a role on the road to the Kentucky Derby through the winter and into next year’s spring.

The handicappers face off in what we like to call “Big-Race Showdown.”
