Champion trainer Ivan Allan's tremendous winning run looks set to continue on the evidence of yesterday's trackwork session. A number of his team, splendidly attired as per usual in their blood-red outfits and gear, went through their paces in fluent fashion. Allan has yet to win this season with his strapping youngster Cream but it can only be a matter of time and it may even be at Happy Valley on Sunday. Cream has improved from race to race without quite managing to get his head in front. He tackles 1,800 metres for the first time on Sunday and the way he's raced and the way he's worked since his battling last-start third over a mile, suggests he should relish the extra distance. Yesterday Allan did not require a serious effort from him, he seldom requires a serious effort from any of his team at trackwork. All the same it was hard not to be taken with Cream's look and fluency as he cantered up the home straight to complete an easy 800-metre piece. Others of Allan's to catch the eye included Quick Speed, who will be one of the leading fancies for this afternoon's sixth event. The son of staying stallion Just A Dancer completed a very similar 800-metre piece to Cream and appears to have gone the right way since his bobbing defeat of Senator. Allan has improved Indigenous markedly since taking over his training. The Champions and Chater Cup winner appears much more solid, much more muscled, especially behind the saddle and across his quarters compared to last season. His last-start victory in the San Miguel Silver Tankard plus his effort in the International Vase arguably entitles him to the tag of the best horse in Hong Kong with stablemate Oriental Express the main challenger. Yesterday, Indigenous looked on great terms with himself as he too enjoyed a comfortable 800-metre pipe-opener in readiness for this afternoon's highlight, the Centenary Vase. Keep an eye out for Allan's Engineman. He was an expensive flop at the Valley last time but there have been plenty of those over recent seasons and he is worth another chance. Engingeman's past couple of hitouts underline he's taken no harm from the experience and is working with all the zest and speed for which he is known. Others to impress in readiness for today were Derek Cruz's New Zealand import, Sweetheart, and the David Hill-trained debut winner, On The Job. Sweetheart has been a trackstar for the past few months and should give a good account of himself in the penultimate contest. On The Job had a serious hitout under Patrick Payne. There is a lot to like about him physically.
