Bart Cummings, Australia's 82-year-old training legend, did it again on Saturday when he saddled So You Think to a 14-1 upset victory in the $2.75 million, Group 1 Cox Plate at Moonee Valley. Ridden by Greg Boss, the 3-year-old son of two-time Breeders' Cup Turf winner High Chaparral burst out of the gate on top and never looked back, defeating the 19-1 Manhattan Rain by 2 1/2 lengths.
