He has proven costly to punters in the past, but a drop in class and a valuable claim should result in Rocket Win squaring the ledger in the opening leg of tomorrow night's Triple Trio at Happy Valley. The Ricky Yiu Poon-fie-trained gelding paid the price for his consistency last season, finding himself elevated to Class Three company after a streak of four placings from five attempts, despite being a maiden performer in Hong Kong. To his credit he still performed admirably but the end-of-season rating reassessments gave the four-year-old the relief he needed and he now looks perfectly placed at this level. Yiu has engaged seven-pound claimer Alex Lai Hoi-wing for the ride and the apprentice was on board Rocket Win when he trialed down the Sha Tin straight on September 1. Rocket Win was slow from the barriers, settling well back in the field before running on well in the final stages to wind up fifth, three lengths behind winner Treasure Planet The performance indicated that Rocket Win had returned well from his break and he looks ideal banker material in a race that appears to lack depth. The biggest threat should come from course-and-distance winner Liaobuqi, who also showed he was ready for business when racing on the speed to win a trial at Happy Valley on Saturday morning. Although Liaobuqi's form reads poorly, the Caspar Fownes-trained gelding did win first-up last season and he looks set to be afforded every opportunity in the run after coming up with gate one for apprentice Jacky Tong Chi-kit. Other worthy inclusions in the opening leg are Sunrise Rainbow and Master Dreamer. The surprise improver may be the Andy Leung Ting-wah-trained Tattenhall Delight, who indicated he was finally heading in the right direction when winning a barrier trial on August 29. The middle pin looks the tricky part of the TT puzzle but Fantastic Win fits the banker bill after coming up with an inside gate for Anthony Delpech. The Me Tsui Yu-sak-trained gelding has an emphatic first-up victory to his credit over this course and distance and his form before the summer break was a lot better than it appeared. He was posted off the track three starts back behind That's It before looking unlucky not to finish closer to Classic Horse after being held up on numerous occasions in the straight. His last effort to finish fourth to Maverick was also excellent because he was slow from the gates and held up at the 400-metre mark before flashing home late to be beaten just under two lengths. With this event likely to be run at a good speed because of the presence of Napa, Triumph, Buddies Power and Arrogance, Fantastic Win should get an easy run in midfield and be able to get over the top of his rivals. The biggest dangers are Classa Supreme, suited by the class drop, the well-drawn Ever King, Rain In Spring and Napa, who looks the best of the speed runners. In the final leg, Happy Kid looks like controlling the race from the front and, with a light weight, shapes up as the one to beat. The last-start winner, who switched to the Danny Shum Chap-shing yard in the off-season, has performed well fresh in the past. He looks set to get a relatively easy time in the lead and shapes as a most appealing banker. Multi Millions and Kowloon Fit will be the hardest to hold out, while Fownes' Brilliant Flash is worth including after a recent barrier-trial success. Seasons Treasure could be the surprise packet on his good fresh form.
