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.\nCummings had won last week's big race Down Under, the Caulfield Cup, with his defending Melbourne Cup titleholder Viewed. Like Viewed, So You Think is owned by Dato Tan Chin Nam. Only fifth last time in the one-mile, Group 1 Caulfield Guineas, So You Think had previously won the 1 1/8-mile, Group 3 Gloaming Stakes. Clearly comfortable with the 1 1/4 miles, 44-yards of the Cox Plate, he traveled the distance on a yielding turf course in 2:03.98, quickening clear through the final three furlongs in 35.31.\nZipping came home third, a long neck behind the runner-up, while 2007 Cox Plate winner El Segundo was fourth. The 2.80-1 favorite Whobegotyou lost for the first time in five starts at Moonee Valley as he finished sixth of 14.\nThe only non-Group 1 winner in the field, So You Think and runner-up Manhattan Cafe were the only 3-year-olds in the race. As Southern Hemisphere sophomores, their feat is the equivalent of Northern Hemisphere 3-year-olds taking the first two places in a Grade 1 race against older horses in April.
