( CNN ) -- Nineteen races and 19 wins . After yet another demonstration of her superiority over five furlongs ( 1,000 meters ) , there are few superlatives left to describe the extraordinary record of five-year-old Australian mare Black Caviar . Unusually for the world 's top-rated sprinter , she was made to work for her victory , with long-time rival Hay List sticking firmly to her flank at the furlong marker . But after a flick of the whip from jockey Luke Nolen , Black Caviar found another gear and pulled away from the field to win the Lightning Stakes at Flemington by one-and-three quarter lengths in front of an ecstatic crowd of 22,800 . Royal approval : Will unbeatable Black Caviar grace Ascot ? `` He had me a bit worried for a couple of strides -- I was a little concerned , '' said Nolen of Hay List . Saturday 's win was Black Caviar 's ninth Group One success and the second time the Peter Moody-trained bay has captured Australia 's premier sprint race , which is also the first leg in the Global Sprint Challenge . It also came after she made her debut over seven furlongs ( 1,400 meters ) in the Orr Stakes at Caulfield the previous weekend . Black Caviar 's incredible run puts her equal with Desert Gold ( 1915 - 1917 ) and Gloaming ( 1919 - 1921 ) for consecutive victories on top-class Australian tracks ( other horses have won more consecutive races on low-grade country tracks ) , although she is the only horse to win 19 without defeat . She is currently ranked joint-second on the all-time undefeated list ; although the run of 54 wins without reply put together by 19th century Hungarian horse Kincsem may yet prove unassailable , even for Black Caviar . But Australia 's favorite racehorse may have run her last race on home soil , for the time being at least , with her trainer conceding that Dubai may well be her next stop en route to the Diamond Jubilee Stakes at Royal Ascot in June -- the target for her connections . `` I 'll sit down with the owners , but if she goes to Dubai she has probably run her last race in Australia this prep , '' said Moody . If , as is widely expected , the lure of Dubai 's $ 2 million Golden Shaheen proves too great a temptation to resist ( there is a $ 600,000 bonus offered as part of the Global Sprint Challenge , rising to $ 1 million if she can win on three continents ) , it will mean Black Caviar 's 20th race could be her toughest yet , pitting her against Sheikh Mohammed 's super colt Sepoy . It throws up an additional challenge as the race is run over six furlongs ( 1,200 meters ) on a synthetic all-weather track , rather than Black Caviar 's preferred turf . A decision on Dubai is expected to be made in the coming weeks , with Moody having already revealed that Black Caviar has had all her vaccinations for both the Middle East and England . `` There is 10 weeks in between the two races , so that presents a few problems , but I am familiar with the logistics of it all and it 's an option we are thinking about . She 'd already had all her vaccinations for the trip to England , so that would n't be a concern if she was to go to Dubai . '' Number 20 proved a race too far for Black Caviar 's spiritual predecessor Zenyatta , the American race mare who was the last horse to put together an undefeated streak of 19 races . There will be many racing fans both back in Australia and around the world who will be hoping Black Caviar can go one better .
June mare Sepoy extends her winning run to 19 races . The Peter Moody-trained horse won the Lightning Stakes in her native Australia . She is currently ranked joint-second on the all-time undefeated list . Black Caviar could now be bound for Australia and , eventually , Zenyatta .
