TOPWEIGHT Shanghai Triumph will appreciate the return to grass and a longer trip in the fifth event at Happy Valley tomorrow night and should not disappoint as a Double Trio banker. Trainer David Oughton decided on an equitrack start for the reliable stayer last time and dropped him back to 1,400 metres on the synthetic surface but the game five-year-old was never really in it. Equitrack is tricky at the best of times and Shanghai Triumph is an honest performer who will battle on rather than show a remarkable change of pace. He is suited by Happy Valley, as he has shown in the past, and this Class Five, 1,800-metre event looks right for him. Claimer Danny L. T. Leung takes over and is probably worth the five-pound claim which brings the weight down from the massive 140 pounds the New Zealand import has been lumping for much of the season. Forgetting his last equitrack run, Shanghai Triumph put in a typical, battling run at his previous outing over the Valley mile when he went under by a head to Able Ride and they came five lengths clear of third-placed Four Winds. As he would be considered marginally better over this trip than 1,600 metres he does shape as a logical banker for the second leg of the bet. The John Moore stable has returned to form with many runners giving good accounts in recent weeks. In this special conditions event for local riders, Moore has called on the services of long-serving Raymond K. L. Tsui for Natural Colour who showed improved form last time when finishing on for Brent Thomson over 1,600 metres. He is a course and distance winner and worth respect here along with Galloping Free and Sky Eagle. Galloping Free ran a fair race on equitrack last week and has course and distance winning form which entitles him to a modest chance while Sky Eagle could be one to surprise. He careered away with a Class Six race very early in the season and has started only twice since, not being sighted in two events over 1,400 metres on turf and equitrack. The 1,800 metres should suit and he is worth including, possibly with Rising Sun although this one would prefer event longer. Trainer Bruce Hutchison struck with Timah in the Manawatu Challenge Cup on Saturday and dour stayer Spirits Bay has strong claims in the first leg of the Double Trio. This is over 2,400 metres and it's absolutely right for Spirits Bay who will be ridden by claimer Vicki C. W. Choi, whom Hutchison has used to some effect over the past few seasons. Spirits Bay was doing his best work close home in a 2,000-metre event won by Miss Piggy 10 days ago and did not have the easiest of runs, being caught wide for much of it. Well suited by Happy Valley and the trip, Spirits Bay looks a very major chance for an in-form stable. And Thor Win is also in form as he showed last time when winning handily for Mick Kinane over 1,800 metres but he has also won over 2,230 metres and is not out of this. Nigel Tiley takes over from totally inexperienced W. L. Ho and that will make a lot of difference.
