LOUISVILLE, Ky. – When the Kentucky Derby is run next May, it will have been 20 years since Hall of Fame trainer Nick Zito won his first with Strike the Gold. It’s far too early to tell if Zito will be able to celebrate by returning with a legitimate contender for the 137th Derby, but it would not seem a huge upset if a colt named Dialed In is here to represent him and longtime client Robert LaPenta.
