Rookie trainer John Size finally conceded his chance to win the Hong Kong trainers' championship at the first time of asking yesterday as a four-timer at Sha Tin swept him to the top of the ladder in sensational style. Shane Dye surged into second on the jockeys' table aboard the Size-trained Century Star, Billion Delight and Toymark to take the trainer level with Tony Cruz and Ivan Allan with 40 winners at the head of the table before Weichong Marwing pumped the rejuvenated eight-year-old Score past Monards in the final race to send Size clear on the leader board. 'I suppose I have to agree now that there is some possibility I might win it, but I'm sure I'm going to have to keep on training winners at the current rate,' he said. 'This is an extremely competitive environment, there are plenty of top trainers here and the system itself makes it tough to keep winning as the horses rise in the handicap. 'It isn't like, say, Australia where new horses are coming into your stable all the time. If I am going to win, I have to win with the horses that I have now. It has probably been easier to get to this point than it is going to be to stay here, but I have to say I'm extremely grateful. 'I could not have expected to have enjoyed a smoother entry to Hong Kong racing than I have had and whatever happens between now and the end of the season, I am very pleased with what I've done.' The laconic Australian has been all but unbackable in private championship betting for several weeks as his waves of winners continue to roll in, but the man himself has been unwilling to discuss the concept as a genuine possibility . . . until now. 'These other guys have been here a lot longer than me and they know the system better than I do, so they may have plenty still to come,' Size said. 'I don't know what pitfalls lie ahead in terms of the programming for the final part of the season and I don't know how many winners it will take to win the title - possibly less than Brian Kan had last year because there are several trainers capable of winning - but I think it's going to be important to find horses that can win more than one race if I'm going to get there.' When Toymark won to take him level with Cruz and Allan, Size took time out to thank his assistant, Benno Yung, for his part in such a successful debut season. 'Before I came here, I was not really aware of the extent of the job that the assistant trainers do in Hong Kong and they do a marvellous job,' he said. 'They carry a lot of responsibility and often I guess it isn't as well recognised as it deserves to be. Benno has been absolutely invaluable to me in the stable and helping with owners and in my communication with staff. I felt now was the time to say thank you.' Size certainly revealed one such horse in the Class Four third race yesterday when Century Star won his maiden at his 26th visit to the races. But despite his non-winning record, Century Star showed the form he had been in at morning trackwork and trotted home like a horse headed for Class Two. 'I was a little worried before the race because he's been going so well,' Size said. 'I didn't know why he would have gone 25 starts without winning when he can gallop as he does. Shane gave him a great ride and he never had to go around any horse but the leader. 'He did pull a little bit when they went slow, but I agree he looked pretty good. Perhaps when the handicapper is through with him and he has to rise in weight and class Century Star might not look as good, but it's nice to see him win for his owners at last anyway.' Toymark's owners probably thought they had seen the last of the winner's enclosure, too, until Size took on the seven-year-old earlier this term. Yesterday's runner-up in the sixth event, Green Century (Marwing) was just a foal when Toymark last won a race - three years and three days ago. Dye said he had asked Size if he wanted Toymark ridden closer yesterday after getting out of his ground and rushing home for minor placings in his last two runs. 'But John just said the horse is racing well the way I'd been riding him and to stick with that plan,' Dye said. 'People have been saying the horse is disappointing because he hasn't won and was giving big starts. But often when you ride those sorts of horses a bit closer, they don't give you the same finish.' When Score took out his third start after an 18 month-spell, Marwing quipped that Size probably owed him a winner after Toymark had pipped him earlier. 'I thought Green Century probably had that race won. Anyway, Score is only my second ride for John and it's lovely to get such an important one home for him. What he has done this season has been quite remarkable,' said Marwing, who also managed a double after winning the second on Lightmaster for Ricky Yiu Poon-fie.
