THIRTY SECONDS into the biggest race of his life, sizzling South African sprinter National Currency charged away with the lead in the Hong Kong Sprint on December 14 at Sha Tin. And then it happened. Not for the first time. Not for the last time. And certainly not for long. The jockey on Hong Kong's unbeaten Silent Witness, Felix Coetzee, began to push and shove and wake the big bay up any way he could. The world was watching, and thought the unbeaten boom horse was in trouble. But in a twinkling, that fleeting moment of doubt was but a memory. Silent Witness dug in, picked up National Currency and threw him aside like last week's paper, then took a pat down the neck from Coetzee and drifted back to snooze mode again before the race was even finished. The world's best turf sprinter. It is an awesome title, and Silent Witness is an awesome horse. Under pressure, when challenged 250 metres from the finish, he pulls out enough to put the race back in the right order and win - some days by further than others, but often not in any way that says the next win is inevitable. But when you have seen him do it 11 times from 11 starts, it is hard to know how good Silent Witness is. Eighteen months into his career, he remains a well into which the equine sprinting world has dropped a pebble that has not hit bottom. This season has seen Silent Witness become the first horse in Hong Kong's professional racing history to win 11 straight races and take the record away from Co-Tack, the horse ridden in most of his victories by Silent Witness trainer, Tony Cruz. Four Group Ones, the official title of world's best and a nice chunk of money, but none of that gets close to summarising a horse who has yet to be tested to the point where anyone knows when he will lie down. Before the International Races in December, the overseas press smirked of local hype and a bubble of optimism that rarely survives such occasions. You do not take on the world and say it cannot win. That is a recipe for humble pie. Well, the recipe is still in the drawer. Felix Coetzee has been on board in all 11 starts and still shakes his head about the horse. He has no doubt what makes Silent Witness great. Attitude. Sure, he has a magnificent physique and he can run like the wind, but what separates the great from the simply good is attitude. 'He is so relaxed. Nothing bothers Silent Witness,' Coetzee said. 'He doesn't spend any energy worrying about things going on around him. He saves everything for his race.'
