With so much talk of Silent Witness in the air now that the international events are almost upon us, memories were revived yesterday of the 1980s legend whose record streak he has eclipsed. Co-Tack's 10-race winning run was the professional era record in Hong Kong for two decades until Silent Witness came along, and while A-Tack won't ever be in that grade, his owners might squeeze a bit of fun out of the gelding in coming seasons. Tsui Tack-suen and Tsui Tack-kong were the brothers who raced Co-Tack under their famous orange, red and white colours and yesterday enjoyed the winner's circle again, with A-Tack bearing the same colours but this time with a different trainer. 'They have had quite a number of horses since Co-Tack, but this is the first with me,' said trainer Gary Ng Ting-keung. 'Wong Tang-ping trained Co-Tack for them and was always their trainer afterwards but, when he retired a couple of seasons ago, they needed a new trainer. They are very good owners so it's nice to win for them.' Eddie Lai Wai-ming sealed his role as Hong Kong representative in Wednesday's International Jockeys' Challenge at Happy Valley this week when he planted A-Tack in the box seat and with blinkers for the first time, the gelding was transformed. 'The blinkers helped but so did having a stronger jockey,' said Ng. 'It was not his fault, but the apprentice last time could not get the best from the horse - he is not the easiest ride - so for Eddie today he had a nice run from the inside draw and was able to win. 'I don't expect too much of this horse, he is only a Class Four horse, maybe he will make it to Class Three, but he has been a slow learner. 'I don't believe in pushing the immature horses because they burn out and A-Tack is still quite immature. 'I think as A-Tack matures and gains experience, he will win his share of races and make a good bread-and-butter horse.'
