Three certainties of life were reduced yesterday to two - death and taxes - when Hong Kong's world champion racehorse Silent Witness tasted defeat for the first time. Unbeaten in his previous 17 starts over 21/2 years, he looked on course for his 18th victory until he was pipped right on the winning post in his first attempt to win at 1,600 metres in the $8 million Group One Champions Mile at Sha Tin. His winning run was ended by the late charge of renowned miler Bullish Luck who, like Silent Witness, is trained by Tony Cruz. The thousands of Silent Witness fans may have left the track disappointed but they had watched a true warrior who fought back with rare courage when Bullish Luck headed him. 'I watched the race with very mixed feelings,' Cruz said. 'Naturally, I am delighted that one of my horses has won the Champions Mile but, on the other hand, we all felt so sad that Silent Witness has been beaten.' Silent Witness' owner, Arthur da Silva, said he was happy with the performance of his horse despite the disappointment. 'No regrets, he has done a really good job. There was no disgrace to lose that way. Every horse has to lose one day ... Just let him take a summer break and stay happy.' Silent Witness fan Ivan Chan said he felt bad after his favourite horse lost. 'I feel very disappointed, not because I lost $5,000 on my bet but because I lost it on Silent Witness,' Mr Chan said. Ada Tung said although she had lost $10,000 on Silent Witness, she would continue to support him. The $4.5 million first prize for Bullish Luck and $1.8 million second prize for Silent Witness also saw Cruz become the first trainer to break the $100 million prize money barrier in a single season. Bullish Luck will head to Tokyo in a bid to complete the Asian Mile Challenge by winning the Group One Yasuda Kinen over 1,600 metres at Fuchu racecourse on June 7. Silent Witness may also join him, with a decision due to be made on Tuesday.
