Popular Australian rider Geoff Allendorf can make a winning return to Macau by taking the 10th event on Beng Seng Star on this afternoon's mixed grass and sand meeting. Allendorf, formerly attached to Bruce Hutchison in Hong Kong and a prolific winning rider in past seasons in Macau, should be able to bounce Beng Seng Star straight out of barrier seven and charge to the front in this minimum sand sprint of 1,050 metres. The other possible leader is Purple Canonise, but he is drawn in barrier 11 and ridden by Sammy Cheang. Given the respective barriers and riders, Beng Seng Star has to be favourite to lead and, so often in sprints on any artificial surface, to lead is to win. Beng Seng Star showed blistering early speed last weekend when ridden by the Pakistani apprentice Imran Khan in the Invitation Bowl, before weakening into sixth behind State Express. Khan went far too fast on him on a heavy track and he just had to knock up, doing well to be beaten by just four lengths in a competitive event after being ridden at such an uncompromising lick. Long-serving New Zealand trainer Joe Barnes has hit a bit of form lately, and his Mr Happy looks to have struck a weak field in the sixth and is rated the best bet of the day. Championship-leading trainer Peter Leyshan can maintain his title challenge by taking the opening griffin event on Triple Fortune, who found the drop back to 1,000 metres against him last time out, when he also had to work hard from the outside barrier. He has only Ozzie Kid to beat.
