Trainer David Ferraris will almost certainly pull the plug on a hit-and-run Melbourne mission with Hong Kong's champion stayer, Vengeance Of Rain. Ferraris expressed his satisfaction with the Derby and Queen Elizabeth II Cup hero as he pulled clear to win a trial over 1,200 metres at Happy Valley yesterday morning but shortly after announced the Cox Plate mission was likely to be aborted. 'I was very happy with the way he won the trial because that was his first serious piece of work and he's not fully wound up,' Ferraris said. 'But the fact that we have not been able to get a race into him before the Cox Plate has become a growing concern. We had today's trial, and the club was offering all possible assistance to stage another on race day at Sha Tin, but it's not the same as a race.' Ferraris consulted part-owner Winston Chow and expressed his concerns that a trip to Melbourne was a virtual 'mission impossible', with the added threat that it could interrupt the gelding's preparation for his major mission - the $18 million Cathay Pacific Hong Kong Cup (2,000m) on December 11. 'The Chow family have been wonderful owners and as much as they'd love to go to Australia for the Cox Plate, Winston said they would leave any decision to me. 'My gut feeling is that we should not be going,' Ferraris said. 'If we could have a race here before we go, that would be a different thing, but the Australian quarantine laws simply don't allow that. I know that to win these big Group One races, a horse needs a couple of lead-up races before producing an absolutely peak performance. I could get Vengeance Of Rain to the Cox Plate all right, but it would be almost impossible for him to perform to his best. History shows us no horses win these big races first-up.' The A$3 million ($17.8 million) Carlton Draught Cox Plate (2,040m) is the only Australian leg of the World Racing Series. Even if Vengeance Of Rain does not start, Hong Kong may have a representative in the John Moore-trained Super Kid, who is already in Melbourne. The Jockey Club executive director of racing, Winfried Engelbrecht-Bresges, said he hoped Ferraris's probable decision to abandon his intended Melbourne campaign caused Australian authorities to re-examine quarantine protocols he described as 'outdated'. 'There is no doubt that Vengeance Of Rain should have been allowed to run in the National Day Cup here in Hong Kong on October 2,' Engelbrecht-Bresges began. 'He would have been in quarantine at the time but Australia is the only country that will not allow a horse to race out of quarantine. What are the chances of a horse catching a disease while racing against other horses in prime, healthy condition? Absolutely none. These quarantine conditions are hopelessly out of date and now it looks like they will cost Australia the participation of one of the best middle-distance gallopers in the world.' Vengeance Of Rain is now likely to contest the Sha Tin Trophy over a mile in October and the International Cup Trial (2,000m) in November.
