Black Caviar may go off at career-low odds of 1-25 when she attempts to stretch her unbeaten streak to 24 races in Friday’s Group 1 William Reid Stakes at Moonee Valley Racecourse in Australia. A 7-year-old mare, Black Caviar is part of a field of seven in the $412,000 Reid, which is run over about six furlongs. There is little to suggest that the competition will offer Black Caviar a threat, reflecting her remarkably short odds. Black Caviar’s rivals include Spirit of Boom, who was third in the Group 1 Oakleigh Plate at Caulfield last month; Luckygray, who won the Group 1 Kingston Town Classic at Ascot Racecourse in Australia last December; and Fawkner, who was second in the Group 1 Emirates Stakes at Flemington last November. Black Caviar is trained by Peter Moody for a partnership. Wildly popular in Australia, Black Caviar has made one start this year, winning the Group 1 Black Caviar Lightning Stakes over about five furlongs by 2 1/2 lengths at Flemington Racecourse on Feb. 16. She was the 1-10 favorite in that race. Last year, she traveled outside of Australia for the first time, winning the Group 1 Diamond Jubilee Stakes at Royal Ascot in England. Regular rider Peter Nolen has the mount on Black Caviar. For the Reid Stakes, a sell-out crowd of 25,000 is expected at the suburban Melbourne track for the evening program. Post time for the Reid is 6:45 a.m. Eastern.
