CHAMPIONSHIP-CHASING Tony Cruz can maintain his title momentum by taking the seventh event on Cambridge Success on a quality Sha Tin card this afternoon with many stars of the future on parade in the Centurion and Kukri Trophies. Cambridge Success has always appealed since arriving from New Zealand as a private purchase griffin last season as he is such a good-looking individual. But like so many New Zealand horses, he has just needed time and a bit of distance - and in this particular case the application of blinkers. Trainer Derek Cruz has certainly not been hard on this three-year-old son of Success Express, mindful of the fact that he has a horse with a definite future even if he hasn't really shown much so far. His efforts to date have seen him drop down to a rating of 33 which makes him eligible for Class Five contests. Last time out he actually ran from a rating of 36 as visiting English jockey Alan Munro put up two pounds overweight and the form he showed in that Class Four event behind the highly progressive Pride And Joy gives him a simply outstanding chance against much weaker opposition this afternoon. And with Tony Cruz battling hard to win his sixth jockeys' title, it looks highly significant that his brother Derek now gives him the ride. It suggests they mean business in no uncertain terms. The bare form of Cambridge Success' nine lengths seventh of 14 to Pride And Joy by no means tells the story as he was coming with a strong run over the final 200 metres only to be severely hampered by Camelot and then by Camelot and America Supreme. Without that interference, Cambridge Success may well have finished third as he went to the line hard held once his path was blocked. That run came over a mile and it was pleasing to see Cambridge Success able to race much handier and show much more speed than on his previous starts when his race form had been very disappointing compared to the way he had shaped in the mornings. The extra zip was the result of Derek Cruz reaching for the blinkers and the move up to a more suitable 1,800 metres (his German dam is from a very stoutly bred family) and the drop down into Class Five, should see Cambridge Success take a considerable amount of beating. He is worth a good bet. Topweight Over The Blues is another who has benefited from the application of blinkers. There has been an added sharpness to his work since Peter Ng Bik-kuen applied them in the mornings. He's a solid quinella and tierce hope along with the Wong Tang-ping-trained Action Win who is an improving young stayer. Action Win won well two starts ago over 2,230 metres at Happy Valley under the now retired Raymond K. L. Tsui. This sparely made gelding then suffered from a poor ride on his only other start, the form of which can be forgotten. Crack claimer, Simon 'Hong Kong' Yim now takes over from Ricky C. K. Chung who was on board last time and basically made a complete hash of it. But the main horse to take in quinellas could be the Ivan Allan-trained Prominence who went well in a trial a week last Thursday down the straight 1,000-metre chute and has always shaped as if needing 1,800 metres to bring out the best in him. He is bred for this kind of trip, being by Icelandic who is a profound influence for stamina. There is one particular run towards the start of the season on which Prominence has to be given a big chance. That came when he ran 51/4 lengths fourth to Lifo over a mile in a Class Four handicap at Happy Valley, racing to a mark of around 35 having run from a rating of 37 once the pound overweight Basil Marcus put up is taken into consideration. This afternoon Prominence runs from a rating of just 28 so he has dropped nine pounds and a Class since that run behind Lifo on 12 October. That, plus the requisite move to 1,800 metres, should be more than enough to see him put in a very competitive effort this afternoon and he is worth taking in one main quinella with Cambridge Success with Action Win and Over The Blues playing a supporting role in the quinella and tierce. It may only be a Class Five event, but the expected battle between Cambridge Success and Prominence is given added piquancy by the fact that Tony Cruz is on the former and Marcus on the latter as they continue to slug it out for this season's riding honours.
