THERE could be no more fitting ride for champion-elect Tony Cruz in today's featured Centurion Trophy than Enthusiasm, given the local idol's real zest for the chase at the moment. Despite the superb effort of Basil Marcus in notching-up five winners last Saturday night at Happy Valley, Cruz continues to make the title race very much a one-act affair. He is riding at the very peak of his powers and his winning efforts have again made him the darling of the punting public. Cruz has ridden winners all over the world but his current enthusiasm for it all was exemplified at Happy Valley in midweek when he stood up in the irons and punched the air in delight as Best Of Luck crossed the line, a clear-cut winner of the modest final event. ''I just like winning - the more the better,'' he said after the meeting. And he's doing plenty of that just now. It clearly took the much publicised and acrimonious split with trainer-brother Derek to bring the best out of Cruz and, in the end, that has been no bad thing for local racing. Jockey Cruz has had to work that much harder since losing the unqualified support of a stable with almost 60 horses and, to give him credit, he has been painstaking in his quest for rides and winners. He has linked up with several local trainers but it has been noticeable that Gary Ng Ting-keung, himself a highly successful local product, has been giving him a steady supply or rides - and winners. And it is Ng who again legs him up today on Enthusiasm with the distinct probability of a win in the important domestic Group Three, $1.25 million Centurion Trophy. Enthusiasm and Cruz go into today's Trophy race on the back of a quite excellent victory at Sha Tin over this 1,600-metre trip on March 13. Enthusiasm had been keenly backed at his first outing on the Happy Valley equitrack having, since his arrival, left few knowledgeable observers in much doubt that he was a first-rate proposition. And that was 100 per cent confirmed on March 13 with a thumping length-and-three-quarters win over Tom's Charge. Enthusiasm was heavily supported, going off the 5-2 favourite, and he was given an exemplary Cruz ride being brought through smoothly from the rear of the field to win going away. On the evidence presented, there is little doubt that Enthusiasm will be very effective when stepped up to 1,800 metres but, kept ticking over since that last, almost effortless, win, he will take all the beating in this event. Enthusiasm goes up five pounds for that win under the conditions of today's three-year-old event and that means he has escaped from the clutches of the handicapper - momentarily. Given the ease and fluency of that last win, with 135 pounds on his back, he would certainly have gone up eight pounds in a normal handicap so he does come nicely into the Centurion. Tom's Charge again opposes and Gerald Mosse takes over on the Patrick Biancone-trained galloper. He is six pounds better off, which is clearly a help, but so emphatic was Enthusiasm's victory it is difficult to see Tom's Charge reversing the placings. Tom's Charge had his previous outing in the Derby but he was not really sighted in the Classic won by stablemate Helene Star and this contest is undoubtedly a lot easier. The weights are headed by Classic Trial winner Happy Guy, ridden on that occasion, as he was in the Derby, by Cruz. Trainer Brian Kan Ping Chee's retained rider, South African Felix Coetzee, takes over on Happy Guy and the gelding must have a definite chance on his Classic Trial win. There were justifiable doubts about the Irish import running out a strong 1,800 metres in the Classic in which he finished a fair sixth, ahead of both Magnified and Tom's Charge, involved in today's Centurion. Happy Guy was most effective in Ireland over 1,400 metres but his effort in making virtually all in the Classic Trial showed that he can handle today's trip given his added maturity. Although Enthusiasm and Happy Guy are likely to be the runners most in demand by the public, it will extremely interesting to see just how well impressive winner Wind Dancer performs in this more exalted company. He was a final ride for visiting British star Alan Munro and could not possibly have been more impressive when winning on February 20. That was over 1,400 metres where he was fourth in the early running, dropped back slightly, and then came on strongly to win going away. He claimed the lead aroundthe 200-metre mark and won as he pleased from Grand Warrior, also involved today. The 1,600 metres will certainly suit Wind Dancer and Derek Cruz has handed the riding chores to visitor Greg Childs who has impressed during his short stay to date. Trainer Cruz also has French import Group Leader involved with Darren Beadman to ride but he is harder to have on form and, possibly, over this trip. However, there is a lot of rain around at the moment and he has very substantial French form on rain-affected ground. That could be worth remembering. Magnified has good English form and there wasa faint hope for his quinella or tierce chances in the Derby but he never struck a blow. It is hard to see him making the necessary improvement here - particularly against horses so obviously in form as Enthusiasm and Happy Guy. Trainer Lawrie fownes is enjoying a golden season and lets his interesting Australian import Super Fit take his chance in the Centurion, ridden by stable jockey Darren Gauci. He was ruled out of Wednesday night's meeting with flu and will certainly need to be at full strength for this ride. Super Fit is a handy type who has justified Fownes' faith but the problem here is likely to be the trip - certainly when measured against Enthusiasm who is suited so well by it. The Centurion could turn into an excellent race and it's certainly good to see one Hongkong event where we have only one blinkered runner. That's Magnified, from the David Oughton stable.
