Jack Frost, the youngest horse in the field of six runners who will face the starter for the A Campbell Trophy, the feature event of Thursday's eight-race card, has only one worthy rival to beat in Wentworth. And though the latter may post dramatic improvement, Jack Frost, if he maintains the fitness displayed during his last victory, should be able to deliver the goods.
