Freshmen trainers Michael Chang Chun-wai and Me Tsui Yu-sak may not have opened their winning accounts just yet, but there were positive signs for both handlers that their turn is just around the corner. Like most trainers starting out, Chang and Tsui do not have a lot of quality raw material to work with. But each of them improved a problem horse at Sha Tin on Sunday and showed themselves to be extremely capable horsemen. Chang, who was formerly assistant trainer to Sean Woods, prepared Wyndam Plenty to take third placing behind Choice And Chance in the second event, an unusually high-rating Class Five race over 1,200 metres. Choice And Chance ran the journey in a new class record time of one minute and 9.6 seconds, which works out to 0.5 seconds better than standard after factoring out the speed of the track on the day. Wyndam Plenty, formerly with David Hayes, had only ever shown two glimpses of form, and both of those at Happy Valley. Not only was this far and away his best Sha Tin performance, he has equalled his career-best performance ratings at his first run for Chang. Equator Kid was another graduate from the Hayes academy, but spent last season under the care of 10-times champion New Zealand trainer Paul O'Sullivan. The former West Australian gelding had some soundness issues and lost all form but since joining the stable of the newly-licensed Tsui, he has been able to signal a return to something like his former glory, going down by only a small margin to Dave's Best and Flaming Lamborgini in the Kwangtung Handicap Cup (race seven). With the 20-20 vision of hindsight, Equator Kid had signalled his wellbeing last Monday with a very good turf gallop with stablemate Dongguan Victory. Working down the back stretch from the 1,800m, the pair clocked 22.5 seconds for their final 400m. Given his poor form over the previous 15 months, all punters ignored the face value of the gallop and let Equator Kid go out at more than 100-1, but there will be no such price about the bay gelding next time he steps out. Dongguan Victory, meanwhile, ran a reasonable race at his debut for the Tsui yard for sixth to Champion King in the Class Four over 1,400m. He may not be one to follow, given his ordinary success rate, but his trainer certainly is. Before being licensed in his own right, Tsui was assistant to Francis Lui Kin-wai, who coincidentally gained his first winner of the new term when Noble Heart took out the final race. Tsui, like John Size and Danny Shum Chap-shing, rides a lot of his own trackwork and is obviously a horseman of substance. The previous three intakes of new trainers in Hong Kong have done extremely well. Last year the Jockey Club recruited Almond Lee Yee-tat, O'Sullivan and David Hall. The year before was another three newcomers - Shum, David Ferraris and Caspar Fownes. Before that, it was Sean Woods and Dennis Yip Chor-hong. Chang and Tsui have started the right way and although each is yet to open his account, the weekend's developments suggest it's only a matter of time.
