There was no hemming and hawing from trainer Steve Margolis a couple days before the 4-year-old filly Good Deed was to make her first start after a long layoff in the Mardi Gras Stakes on Tuesday at Fair Grounds. For lack of an allowance-race comeback option, Margolis had worked Good Deed with an eye toward this stakes return. The filly had trained strongly. She was ready to win, Margolis thought. And he was right.
