CLUB jockey Glen Boss came emphatically in from the cold at sultry Sha Tin yesterday with a winning treble that included a smart newcomer for David Hayes as the champion trainer also celebrated a welcome revival. It has been a frustrating time for both Boss and Hayes but it all came right here with the latter landing a winning double. Boss went into the meeting with a lone winner from 75 rides and a confidence-draining string of minor placings behind him on horses who came agonisingly close. But he had every reason to leave the track smiling after partnering Northern Flyer (5-1) in the opener for Tony Millard, useful Helene Express (15-1) for Hayes and lightly weighted Mastana (9-1) for Lawrie Fownes. And Hayes could also afford to be more than pleased as his first winner was also a handy newcomer in Financial Supreme (7-2), who won the Class Four second event in the style of a good horse. Said Hayes: 'It has been a quiet time for the stable, definitely a bit of a slow start. But it doesn't take too many days like this to have you right back up there. 'I do think that these are both nice horses but I have no fancy plans for them. We will take it along slowly. Helene Express won well and I have hopes for him on this run and what he did in Australia.' The real star of the Sha Tin show, however, was Trillion Win, who produced a display of complete excellence to dominate the Class Three penultimate event on the card. Last year's griffin star simply hacked up under Douglas Whyte and one does not have to be a genius to say that Trillion Win is heading for the top. He was not anywhere near tightened up for his seasonal debut and won eased down by 4.5 lengths. Trainer Ivan Allan, who bought the son of Last Tycoon in New Zealand, looked delighted with the performance. Not disagreeing with an assessment that the three-year-old was probably just over 70 per cent fit, Allan said: 'I started him over a mile first-up because I did not want Douglas [Whyte] to have to bustle him along. He was able to find the front quite easily and he then switched off which was very pleasing. 'I told Douglas that he might start feeling it in the last 50 metres because we had not done that much with him. But it didn't seem to matter. 'It is exciting and he's only a baby. Actually, a couple of his baby teeth came out when we were saddling him. I have no concrete plans for him now, he will take his time through the classes.' Trillion Win, who won his only griffin start over the longer sprint at Sha Tin, was 2-1 to win here and scored quite brilliantly from outclassed High Spirits (9-1). Helene Express is certainly no slouch and Hayes can reasonably expect this Group Three winner at Randwick to be scoring again. He was drawn on the extreme outside in the 14-runner field for the sixth race, a Classes One and Two event over 1,400 metres. Ironically, Hayes supplied the favourite in Special (7-2) but he did not get much of a look-in against his impressive stablemate, who won by three-quarters of a length from Sweetheart (10-1). El Viento (6-1) finished third but was outgunned completely by the winner. Mastana, the final leg of the Boss treble, was also the second leg of a double for trainer Fownes. Mastana, easy enough to back in a race where betting was dominated by Apples And Oranges (5-2), strode right away from them in the straight under a light weight and one would have to fancy his chances of winning again in Class Five. It may well pay to put a line straight through Apples And Oranges, who broke well, seemed to travel all right to the turn but was soon under pressure and wilted. Trainer Allan was not in the mood to make excuses. 'Completely disappointing. I am not a great fan of the horse but I thought he could win,' he said. Cash Fortune (30-1) finished second to Mastana and ran a gutsy race for trainer Bruce Hutchison and jockey Steven King. South African champion trainer Millard is also clearly settling into Hong Kong in his first season here. Northern Flyer won the first event tidily, carrying on for Millard where he left off at Happy Valley on Wednesday night when stayer The Establishment gave him his second career winner here.
