Trainer John Size says Shane Dye will be the new rider for Hong Kong's superstar galloper Electronic Unicorn when he tackles the second leg of the Triple Crown, the Hong Kong Gold Cup over 2,000 metres, on Sunday. 'Shane has never been on Electronic Unicorn at all, but it didn't take a lot of talking to get him to ride the horse,' Size said yesterday. 'Of course, we would have liked Robbie Fradd to ride him again next week but, since that isn't possible, I'm sure Shane will do a good job. There's nothing in his favour, though, as the horse has to step up to run the 2,000 metres this time and he hasn't been able to do it before.' The gelding's regular partner, Fradd, is under suspension from riding until March 8, pending further information surrounding his arrest and questioning by the Independent Commission Against Corruption during Operation Green Grass on February 6. Neither Fradd nor any of the other 19 people arrested and released by the ICAC during the operation have been charged with any offence, but the Jockey Club moved on February 8 to suspend both he and fellow jockey John Egan pending further information, thus throwing open the Gold Cup ride next weekend. Ex-Sydney trainer Size and former Sydney-based rider Dye celebrated their new union with a romp through Sha Tin for trebles apiece yesterday and the rider is hoping his current momentum can carry on to the Unicorn's big test. 'I'm only the caretaker rider, but I feel very honoured indeed to be asked to ride Electronic Unicorn. I feel I'm having a terrific season. I've been ticking the winners over and to ride three today is fantastic,' he said. 'But this is something special. Electronic Unicorn is the favourite horse of Hong Kong, so it's a great responsibility, but I'm really looking forward to it. He looks a sensation and if he can bring his Stewards' Cup form up to the 2,000 metres, he should win, unless he strikes a wet track or something unforeseen like that.' Dye's treble at Sha Tin took him to 31 wins for the term to date, still 10 behind championship pacemaker Douglas Whyte, but snapping at the heels of Weichong Marwing (33) for third. Dye was not specific about his other offers in the Gold Cup, but said there had been no agonising decision. 'I would have ridden one of David Hayes' runners, but I jumped at the chance to ride this horse for John,' said Dye, who made his name in Australia riding the big name gallopers in big race wins, but to date has racked up just one major in Hong Kong, last year's Classic Mile on Charming City. 'Still I'm only keeping Electronic Unicorn warm for Robbie. It's really bad luck for him that he can't ride the horse in the Gold Cup after being on him all season. But I have no doubt that he'll be straight back on him once he is riding again.' Despite Size's queries on the distance, Electronic Unicorn will start a red-hot favourite in the Gold Cup following an almost perfect season since joining Size. He has met defeat only once, when second to Eishin Preston in the Hong Kong Mile on International Day, and has since crushed a top-grade field in the Group One Stewards' Cup at 1,600 metres in the first Triple Crown leg. Even if he wins next Sunday's second leg, Size has already indicated the gelding would be extremely unlikely to tackle the final 2,400-metre leg of the series in the Champions and Chater Cup.
