Yesterday's five-strong Sha Tin barrier trial session down the straight 1,000-metre chute appeared to produce future winners aplenty headed by Jeune King Prawn, Good Power and All The Best in the very first heat. The Ricky Yiu Poon-fie Jeune King Prawn was always in the van before holding Good Power by a head in this opening heat with a similar margin back to All The Best in third. Jeune King Prawn has been working and trialling well for some time now and should go close on debut. Unlike his name suggests, he is not by the Melbourne Cup winner Jeune but is a two-year-old son of Danehill. Good Power, an International Sale son of Jetball, is learning at the gates and appears to have a stack of natural ability. The Tony Cruz-trained youngster came from mid division yesterday to run on into second and is another to jot down for the future. This was only a slowly run heat but these two, in particular, have shown up so consistently well in virtually all they've done it would be a surprise if they weren't worth following. All The Best previously trialled as recently as last Friday when he was very much looked after on the all-weather surface before staying on really well in the closing stages. Yesterday he again kept on well and appears to be progressing along the right lines for trainer Wong Tang-ping. All The Best is another International Sale purchase. He's a son of Last Tycoon and is yet further evidence of just how well this Sale has worked out this season. There have already been winners out of it and there promises to be a stack more. It could turn out to be a vintage year for the Sale. Yiu and Weichong Mawing, on the mark in the first trial, also took the second, this time with the griffin Victory Marble who has had one run to date down the straight 1,000-metre chute when green before making some late headway. Yesterday he basically made all the running, showing more dash to win in a fair time of 58.8 seconds. He beat the established griffin Century Star by half a length with four lengths back to the Peter Chapple-Hyam-trained Energetic Prince in third. Energetic Prince is another who can gallop, though he gives the impression he's going to need at least one run. John Moore has already gone on record to say he's collected any number of nice young horses around him for next season. His Viking Dancer, another two-year-old son of Danehill, ran on into sixth in this second heat could just be one of them. Peter Ho's Jade Ruyi was never out of 10th behind Victory Marble but does enough to indicate he's also notebook material. After these first two heats it was much more exposed stuff with Yiu completing a trial treble with Feel Legend in the third. The Derek Cruz-trained Shadeyiev took the fourth heat and should be fitter when next seen out as he'd missed work prior to his recent outing. Lawrie Fownes' Dancing Spirit was untroubled to win the last trial by four lengths from Moore's Stylish.
