Last year, Uncharacteristic, who was claimed by trainer Robert VanOverschot for $8,000, parlayed a win in the $100,000 Manitoba Derby into a victory in the Grade 3 Canadian Derby. Trainer Robertino Diodoro is hoping to duplicate the feat with Red Knobs, a $50,000 claim, who figures to be favored in the most prestigious race at Century Mile Saturday. The 1 1/4-mile Derby drew on overflow field of 13 3-year-olds with Countrified mired on the also-eligible list. All starters will carry 126 pounds.
