Black Caviar, Australia’s reigning Horse of the Year, extended her unbeaten streak to 16 races with an easy win in the $1.03 million Patinack Farm Classic at Flemington Racecourse on Saturday. Ridden by a confident Luke Nolen, Black Caviar stalked pacesetter Buffering for the first half of the Group 1 race over about six furlongs, took the lead in the final quarter-mile, and won without significant urging by 2 3/4 lengths. Black Caviar was sent off at odds of 1-25. Buffering, who was 40-1, held second, finishing a length in front of Mid Summer Music. Scenic Blast, stakes placed in 2010 during a California campaign, finished fifth in the field of seven. Black Caviar, an Australian-bred mare by Bel Espirit trained by Peter Moody, is expected to have one more start this calendar year, in the $502,000 Winterbottom Stakes over about six furlongs on Nov. 19. Moody has mentioned starting the 5-year-old Black Caviar in races up to a mile in early 2012, before embarking on a European campaign focusing on the Royal Ascot meeting in England. On the same Flemington program Saturday, Albert the Fat, a 16-1 chance, pulled an upset in the $1.03 million Emirates Classic over about a mile, holding off King’s Rose, who was ridden by Nolen for Moody. The Group 1 Emirates Classic was Albert the Fat’s second win at that level. A 7-year-old Australian-bred gelding by Magic Albert, Albert the Fat won the Group 1 BTC Cup in May 2010.
