An out-of-sorts Silent Witness presented an opening and Eric Saint-Martin on Scintillation rushed in to fill it, with the Danehill sprinter stylishly claiming his second career Group One in yesterday's $4.5 million Centenary Sprint Cup. Saint-Martin has been Scintillation's partner in every major piece of work in recent weeks and the Frenchman knew after riding him in an impressive riverside gallop on Thursday that the big brown gelding was ready to step up. With Saint-Martin executing a tactically perfect race, Scintillation had the last run on Hong Kong Sprint winner Natural Blitz before forging clear to post a half length margin over the international day hero. Pre-race favourite Silent Witness could only manage seventh place, leaving his thousands of fans very disappointed. In doing so, Scintillation became a member of a rare club of horses versatile enough to win at racing's ultimate level at 1,000 and 1,600 metres, the distance of his previous Group One victory in the 2005 Classic Mile. It was Saint-Martin's second Centenary Cup - after Quick Action for three-times champion trainer Ivan Allan in 1997 - and the jockey was quick to assure listeners that Scintillation is the superior animal. 'This horse has a huge turn of foot,' Saint-Martin said. 'He has great acceleration and is a genuine Group One horse. 'I really looked after him in Thursday's gallop because he'd done three strong pieces of work the previous week and I didn't want the edge off him for this race, after all it was only 1,000 metres. 'He came down the riverside gallop beautifully, and I never moved on him. He was always strongly on the bridle.' Scintillation began his career with Allan but was transferred to his former assistant, Danny Shum Chap-shing, after Allan retired from training in June, 2004. The beautifully bred galloper, a product of the Hong Kong International Sale, has now won 10 races and $16 million in prizemoney for owner Hui Sai Fun. Saint-Martin was the first to admit this was an opportunist victory. 'If Silent Witness is 100 per cent right, then he has to beat them, but he wasn't and in racing we have to take advantage of every opportunity that comes out way. 'Danny has done a great job to have this horse absolutely right on the day, and he's carried it off.' Scintillation's Achilles Heel is his tendency to lay to the right under pressure. Saint-Martin plotted brilliantly to make an asset out of his weakness, shadowing leader Natural Blitz throughout. 'I followed, followed, followed Natural Blitz all the way,' the jockey said. 'And when I made my run, I tried to be as close to him as possible. My horse is a much bigger horse than Natural Blitz and if I was alongside him, and he laid on him slightly, there was every chance that Natural Blitz would be intimidated. And that's how it worked out.' Glyn Schofield had no excuses on Natural Blitz, but acknowledged Saint-Martin for his execution of the stalking role. 'The way Natural Blitz races, he tends to be a bit of a sitting shot,' Schofield said. 'But he raced very well once again. Derek [Cruz] has him in tremendous form - he's run his heart out and only gone down narrowly to a very good horse.' Planet Ruler ran another great race for third, a neck behind Natural Blitz, who had also shaded him in the $10 million Hong Kong Sprint in December. Outsider Noble Crusader ($300) did best of the three Tony Cruz-trained runners with a workmanlike fourth.
