Martha Stewart fans — and detractors — got a shot at the ultimate hunch bet yesterday when Stock Tip, a 3-year-old daughter of a mare named Cookingwithmartha, was entered in the fifth race at Saratoga Racecourse. Apparently, there wasn’t much insider information traded about the dark bay filly’s talents, as she eked out a huge upset (scroll down) at odds of 54-1. Naturally, Stock Tip had to survive a claim of foul play from a rival’s jockey before the race was declared official, but she paid $110 for a $2 win ticket to those who kept the faith.
