John Moore's Constellation proved last time that he is a horse to follow again in the bottom grade. On his last start, Constellation was run down by Wonderful Boy close to the line but stuck on gamely and based on that performance he should be considered as a banker in the middle pin of the Triple Trio on Sunday at Sha Tin. Champion jockey Douglas Whyte has stuck with King Of Spades, who ran well in defeat when finishing runner-up to First Knight over 1,400 metres. He will appreciate the extra furlong and must be given due respect. Amicable looked a touch unlucky when finishing third to Sweet Smile over the course and distance and now that he has hit form, he looks a decent chance to figure in the finish. Spectacular Times had excuses in defeat on his last attempt. He should improve from a decent draw this time, while Kiwi Dash is capable of filling a minor place. Finding a banker in the opening leg is no easy task but it is worth chancing Jet Rise. He bounded in the air and lost his rider on his last start but his form prior to that had been sound enough to warrant serious respect in the bottom grade. He should also appreciate the gear change along with the step up in trip. Timber City will prove hard to run down on the lead and based on his overall form looks a worthy chance of hitting the frame. Lucky Packet, who ran well in defeat last time, will need luck from the outside gate this time around but should still figure in the finish. The recent form of Premier Cru has been creditable and he is also competitively weighted, while Magnificent will appreciate the drop in grade and has the ability to fill a minor place. The logical option for a banker in the final leg is Hawkie Star, who has the blinkers applied for the first time. He has picked up prizemoney on all three outings and has been knocking on the door for a win. He will need more than an ounce of luck to break through from gate 13, but should manage to hit the frame. Champ Dragon made every post a winner on his last attempt. He strikes similar opposition and cannot be denied a top chance of a repeat. The recent form of Enriching has been sound and even though he has drawn gate 11, he merits strong consideration. Happy Kid should appreciate the return to Sha Tin and is well handicapped, while Master Able has drawn ideally in gate one and will have every chance to figure in the finish. The HSBC Premier Juvenile Sprint Trophy is the third event, and Good Ba Ba looks the one to beat, based on his outstanding griffin form. The Caspar Fownes-trained Ocean Tranquil looks the most likely to cause an upset, being undefeated from two outings and there is a lot to like about his form. Stablemate Toffee looks a solid chance of hitting the frame, while Lucky Stravinksy has finished no worse than second from four attempts and must be added to the shortlist.
