YOU can't keep a good man down as visiting riding star Alan Munro showed when moving back among the winners at Sha Tin last night. Munro scored on Neville Begg's improving young Magic Joy in the evening's third event to register his second success, having opened his account at the first time of asking on Winning Colors at the beginning of the month. The English Derby and Irish Derby-winning rider said: ''I've been coming in for plenty of support and getting plenty of rides. ''I'm happy with the way things are going and was delighted to ride a winner for Neville tonight as he's been giving me some good rides.'' Magic Joy, who lost his way last time when racing under lights and at Happy Valley for the first time, bounced back to notch a decisive win from Ivan Allan's progressive son of Pompeii Court, Applause. Magic Joy benefited from the move to 1,400 metres as well as the return to Sha Tin but Munro, who took the initiative and rode him forward from a bad draw, reckoned this distance is as far as he wants at the moment. ''He won well but fatigue was beginning to set in at the finish,'' he said. Hong Kong rider Jackie Tse also came in for a welcome winner - his third since a four-meeting careless-riding suspension - when picking up the chance mount on Peter Ng Bik-kuen's Lucky Clover after regular rider Danny Lee injured his ankle in the stalls on Intermac Supreme in the seventh. Tse took full advantage of his good fortune, producing a copybook ride along the rails to hold Survey King and Crown Commander by three quarters of a length and a neck. Another Hong Kong rider doing well is K. H. ''Little'' Hung who landed a considerable touch for connections when conjuring a faultless performance from Thunder Bolt, the 37-1 winner from favourite Gay Pegasus II in the eighth. The popular Hung may be in the twilight of his career but he has seldom got more out of a horse than he did from Thunder Bolt, holding no less than Mick Kinane at bay over the last 300 metres - and this despite dropping his whip. Tony Cruz kept tabs on the prolific Basil Marcus in the jockey standings when Prince Baikal completed a hat-trick of wins by taking the second race. There were a number of bleeders through the night as the temperature dropped. Just spare a thought for owner Archie Da Silva who loves his racing as much as any owner in the game. His Nervous Witness bled in the Police Cup to complete an unwanted double for Da Silva as his other horse, Clever Witness, bled on his last outing.
