TRAINER Wong Tang-ping supplies the logical banker for the second leg of tomorrow's Double Trio at Sha Tin with well-graded youngster Manley's Star. The four-year-old really woke up last time out when finishing second at big odds to Invincible over this same 1,600-metre trip back on January 22. He was a length and three quarters away from the winner having been badly drawn. That form received a huge boost two weeks ago when Invincible came out in Class Four and went under by the narrowest possible margin to Asian Glory with some useful performers finishing adrift of him. Manley's Star has drawn perfectly in barrier one and Eric Legrix, who partnered him last time, will be confident of doing well. He has gone up five pounds for that second placing but the form is so obviously good that Manley's Star must be taken to win here. This is a moderate field but trainer David Hill's Four Winds has come on from a recent outing where he finished five lengths adrift of Smart Boy and may reverse form with bottomweight Treasure King who beat him home. He should easily hold Scan Lord, Winford, Caramba and Right Stuff who all finished behind him last time. Treasure King remains a DT chance and Chivalry should also be considered following a good run on equitrack last time out. Trainer John Moore produced a useful-looking winner last time out in Make Merry who remains in Class Five and looks a solid banker for the first leg of the DT. Make Merry won quite cosily over 1,400 metres on yielding ground and will definitely appreciate the step up in distance to 1,600 metres here. Make Merry has been put up 13 pounds which is a lot of weight for what was a reasonablewin. Connections have certainly been done no favours. Source Of Life is getting expensive to follow and Danny Lee takes over tomorrow from claimer Victor C. F. Chan. Source Of Life must be ridden from well off the pace but he is a ''must'' for a DT leg. This will be harder for Smart Boy but he remains a chance.
