HALLANDALE BEACH, Fla. – A year ago, trainer Shug McGaughey won the $400,000 Fountain of Youth Stakes from the rail with Orb. On Saturday, the Hall of Fame horseman will defend that title from the other end of the post-position spectrum after his Top Billing drew post 12 in a bulky field of 13 3-year-olds entered Monday for the Grade 2 Fountain of Youth.
