Stable jockey Darren Beadman may abandon Collection when last season's Derby winner resumes in the Sha Tin Trophy (1,600 metres) on Sunday week after a barrier trial yesterday that trainer John Moore conceded was 'lacklustre'. Though Collection beat home multiple Group One winning stablemate Viva Pataca by some two lengths in finishing fifth in the 1,000-metre trial up the straight, he looked to be under some pressure to hold his position in the run to the line while the older gelding did it with ease. Moore (pictured) has already tipped Collection to usurp Viva Pataca for the Horse Of the Year honours by the time this season is over, but said Viva Pataca was the one coming to hand more quickly for the start of his campaign. 'I've left Darren the choice for his ride in the Sha Tin Trophy - he can ride Viva Pataca or Collection and Weichong Marwing will ride the other one,' said Moore. 'I agree, Collection's trial wasn't that good, it was a bit lacklustre. But that was due to the body weight he has put on since he last raced, and he was carrying a little bit more than I would have wanted. 'It's not a concern, it will come off with training and he's going to be on his racing weight by the time the International Races come along, but it's probably fair to say that he isn't as advanced as Viva Pataca for that race first up. Viva Pataca is the kind of horse who doesn't put on a lot of condition when he has a break, and his trial was very nice.' The Sha Tin Trophy 12 months ago was the race in which Viva Pataca stunned the likes of Good Ba Ba and Fellowship with a sizzling sprint under top weight to win fresh-up and, if Moore is any guide, the evergreen eight-year-old is well up to doing it again. 'The riding boy who partners him told me that he thinks Viva Pataca is going even better than he was this time last year,' he said. Moore also reported that rising sprint star Happy Zero pulled up very well after his impressive 1,000-metre win last Sunday and would go to the International Sprint Trial (1,200 metres) on November 22 without another race. 'He's so clean-winded and came through Sunday in great form,' he said. 'I think all he'll need will be a barrier trial in early November and he'll be ready for the International Trial race. 'On the other hand, Inspiration will run again in the Premier Bowl on October 25. 'I haven't decided who will ride him there under handicaps. If Sacred Kingdom runs it would change the weights quite a bit, then Darren will probably ride Inspiration. If Sacred Kingdom misses that race, Inspiration will have the grandstand to carry again and I might claim on him.'
