VETERAN riding great Lester Piggott and top Australian Darren Beadman both had a nightmare time in the final race at Happy Valley last night. Piggott was next to last when Sterling Town (20-1), making his Hongkong debut, failed to negotiate the tight Valley bends and was clearly not happy with equitrack, floodlights and an excited crowd of 30,000 fans. And Beadman had an alarming time on Happy Years (4-1), which finished a long last, clearly distressed, and there is a severe doubt over the future of the horse, trained by John Moore. Melbourne Cup-winning jockey Beadman said: ''I have never experienced anything quite like it. The horse was actually whinnying in distress at the first turn and I did my best to pull him up.'' Happy Years returned from a race early in his career with a heart murmur and senior vet Keith Watkins will be discussing the horse's future with trainer Moore. The Moore stable is going through a sticky patch having lost griffin Through Train in bizarre circumstances earlier this week. The horse dropped dead after a routine injection. The Brian Kan Ping-chee galloper Chancellor became the third horse in three days to die when he was put down after breaking down in a Tuesday trial. Sprinter Baby Wave, a boom griffin in his juvenile year, was put down on Monday suffering from laminitis. While Piggott was out of luck last night with his only ride at the meeting, he can look forward to better times at the weekend at Sha Tin. Ivan Allan has engaged him for Grand Warrior, an English import having his second start, in the Association of Hongkong Racing Journalists Challenge Cup feature race. Grand Warrior, clearly no respecter of reputations, dumped Piggott at the track on Tuesday but then went on to work solidly in preparation for the 1,400-metre event. Meanwhile, trainer Lawrie Fownes has taken delivery of Class One sprinter Nitrogen. Fownes, in a four-way tie at the top of the trainers' championship going into last night's meeting, is now one off the pace. The win of Star Of Pakistan took Frenchman Patrick Biancone to a one-winner lead and he remains favourite to capture his first Hongkong title. Tony Cruz, meanwhile, continues to set a hectic pace in the jockeys' championship, bringing home another double last night.
