TOPWEIGHT Innovation can wrap the day up on the right note for punters at Sha Tin by taking the final event on an interesting card. Innovation will have benefited enormously from his first-up run over 1,400 metres where he came from a near-impossible position to finish a fighting second to Gold Yue Yee who made all in most impressive fashion. The winner that day actually ran them off their feet and it was no race at all - but that will certainly not be the case in this Classes One and Two, 1,600-metre event. Innovation has better form over shorter and longer trips than the Sha Tin mile, but the manner in which he swamped everything bar the winner last time suggests the Lawrie Fownes-trained galloper is well up to this assignment. Most attention will be featured on bottomweight Bumper Star, a most progressive type from the stable of leading trainer Patrick Biancone. Bumper Star won most resolutely last time, but now steps up in class and this will be a test. He has won three straight and not too many horses in Hong Kong can make it four on end, but Bumper Star will definitely be there at the finish. Biancone has a good opinion of the horse he took over during the summer, but said: 'It is from this point on that counts. He has been winning against lesser opposition, but now that he is in this grade we will really find out how good he is. 'I do like the horse and I think he has the necessary ability. But we will only know on the day.' Northern Celadon is an interesting runner for David Hill and John Marshall.
