Star English jockey Brett 'Double' Doyle looks the jockey to follow at this evening's mixed Sha Tin turf and dirt meeting. Doyle has a heap of good chances through the night but especially the seemingly well-handicapped Genius in the feature event, the Lusitano Challenge Cup, dirt specialist Winning Express in the fifth and the newcomer Decouvert in the second. All are for his retaining trainer Andy Leung Ting-wah whose stable could well be poised to hit one of its typical purple patches of form. Genius, himself, has come to form around this time of year in each of his past two campaigns. That may well be more to do with Leung's methods than anything to do with the horse's own idiosyncracies. The reasons, however, are only of academic importance. More relevant is the fact he appears set to take all the beating in the feature event. Last time out he stayed on strongly to run half a length third to Ho Ho over tonight's mile course and distance on exactly the same 'C+3' circuit. With the rail out it is usually hard to make ground at Sha Tin as it was on that occasion, especially given the way that Eric Legrix appeared able to get a breather into Ho Ho in the third quarter before sprinting for home in what was a consummate piece of race riding. Given the tempo and the quality of opposition Genius faced, it was a highly creditable effort. It was also by far his best run of the season and one which pointed to a imminent success. The rail position is not in his favour as the emphasis should be once again to racing near or on the speed. But Genius should come on for that run - he's certainly worked that way - and he looks to be tackling easier company. What's more, towards the end of last season he was able to run to a mark of 100, according to my private handicap, when a luckless 1.75-length fifth to Winning Supreme over the Happy Valley mile and to a rating of 97 when a neck second to Valley specialist Pinky Long Legs at the same trip. Tonight he's running from a mark of 87. The progressive Score and track star Medic Pearl may give Genius most to think about though Cottage View, yet another example of a horse growing a leg once dual British champion Kieren Fallon jumps on board, can't be ruled out of the tierce. Winning Express is one of the most consistent dirt horses in town and doesn't appear to have much to beat in a modest fifth event. Doyle's mount comes into the race off a strong second at a mile on the dirt but is arguably even more effective at this trip. Monopoly Senior, Sharp Shooter, Pakistan Hero, Delight Express and Speedstar should ensure there is no loitering and this should allow Doyle to sit just in behind the pace and pounce when the leaders start to compound in the last 150 metres or so. He may have most to fear from Forever Prosperous, Star Of Hong Kong and Lucky Glory. The newcomer Decouvert could be too good for them in the second while Doyle, one of the best young riders to come out of Britain in years, could well be in the thick of things, too, on the dirt-loving Winning Glory in a highly competitive fourth event.
