IRISH champion jockey Mick Kinane wound up the greatest year of his career with a short-priced winning double at Happy Valley last night. Kinane heads for a family holiday today and will not be riding at Happy Valley next Wednesday when racing resumes after the Christmas break so he wrapped up the year as he began it - winning. There was plenty of Christmas cheer for other Northern Hemisphere riders as Alan Munro clicked into top gear after a slower start than usual to his stint and Walter Swinburn continued his high-flying campaign. Kinane brought home Shanghai Triumph (3-1 favourite) a clever winner of the first event where he ran down Mr Nice Guy (8-1) close to home in the modest 1,800-metre event and then continued the excellent season of trainer Lam Hung-fie when scoring easilyon Saint Dragon Hill (5-2 favourite) in the sixth event. But he was out of luck with Muster Mark (5-2 favourite) in the feature race on the card, the Hong Kong University Alumni Association Challenge Cup, and sprinter Classabove (6-1) finally found the company too tough in the final event on the seven-event turf card. Swinburn has been on the winning trail since arriving for his three-month stint and scored with bottomweight Jacko (9-2) in the Classes One and Two second event. It was the sixth success in three weeks. And Munro, who won with his first ride, made it two wins in four days when Super Structure (5-1) obliged for the Lawrie Fownes stable in the final event - making it a double for the popular handler. Fownes had seen somewhat erratic customer Picador (20-1) cause an upset in the Class Three short sprint, the fourth event on the programme. But it was a local jockey and trainer combination who pulled off the night's best coup when 16-1 chance Space Rock won the featured HKUAA Cup. Trained by Tony P. H. Chan and ridden by Johnny K. S. Ho, Space Rock was never off the bit in winning the Class Three, 1,800-metre event by 13/4 lengths. Space Rock had been at 28-1 overnight but the quote was sliced in half in early betting and it was soon clear that the plunge was bang on target. Space Rock travelled like a dream for Ho and was being hailed the winner a long way out. He had run a bold race when finishing on over 1,650 metres behind Nervous Witness over 1,650 metres at Happy Valley two starts back and never got warm over 1,400 metres at Sha Tin on International Races Day when handled by New Zealand champion, Lance O'Sullivan. But it was a different matter last night when stepped up to his right distance and he is going to win again. He is by the Australian sire Semipalatinsk who had the very good stayer Breakaway here a few seasons back. Space Rock proved far too strong for New Airport while Long March showed that he is on the right track with a third-placing in the feature event. The Peter Tse Yan-sid galloper did not seem to travel too kindly for John Marshall and looks certain to be far better off at Sha Tin. Watch for him there over 1,800 metres or even further. For Kinane it was a fine end to an unforgettable year. He said: ''I had a book of rides where I thought I had to get a winner or two. It was hard to figure out which was the best of them but I thought Shanghai Triumph would have come on enough from his last run over a mile to be right in the firing line. Heran very much as I expected. ''I had worked Saint Dragon Hill earlier and I thought he went very well in that. ''Classabove was always going to be a risk. He is a horse who does enough to win, no matter what class he's in. In the past he has missed the start but he got away well tonight and I could not complain about the run I got. ''In the straight we were there if we were good enough and tonight we just weren't.'' And Tony Cruz wasn't left out of the action. He cut the lead of Basil Marcus to just one winner when Fighting Strike (4-1) came home very strongly to take the third event. Fighting Strike, who has been thereabouts in recent runs, cut down Bogie's Pride (5-1) close to home in the Classes One and Two longer sprint.
