LONG-SERVING trainer Bruce Hutchison produced a Christmas cracker at chilly Sha Tin last night with a 91-1 double that keeps him on track for his best season in years. The snowy-haired Hutchison played Santa Claus to some of the 29,000 punters shivering on course who followed the fortunes of dour stayer Spirits Bay (13-1) in the fourth event where he looked one of the few logical hopes over the testing 2,400-metre trip. But once again on the riding front it was Basil Marcus who stole honours with a superb treble, rounding it off with V-Ming (8-1) who made all in the last event before racing goes into a 11-day break over Christmas. Marcus had given predictably solid riding displays earlier to score on enigmatic William's Tact (9-1) and Fighting Strike (6-1) to end 1995 as he started it - riding winners. Producing a string of winners is little more than business as usual for Marcus but Hutchison's neat double came as another fillip to the Perth-born trainer. The double was initiated by French champion jockey Thierry Jarnet who gave a polished display to land dirt-loving Light-Hearted (7-1) in the opening event. It was Jarnet's first Hong Kong winner. Scots-born visiting Club rider Richard Quinn rode Spirits Bay perfectly for a solid win over raging favourite Treasure (2-1) who could not find enough under replacement rider Eric Legrix to trouble the winner. His riding arrangements certainly had Hutchison beaming and he said: 'I have said from the day it started that the Club jockey scheme was exactly what smaller stables needed. 'I have had two excellent riders on my horses tonight and they both rode them to perfection. 'It is a very pleasant way to go into Christmas because we did fancy them both on an each-way basis - particularly Spirits Bay. 'I simply told Richard not to rush things because there wouldn't be that many in the field who would see out a strong 2,400 metres. 'The distance was really the key to it,' said Hutchison, who has now moved to nine winners for the campaign. Legrix took over on Treasure, a brilliant track worker, when Tony Cruz gave up his rides after partnering Millions More in the second event. He was badly shaken on Saturday when Chalky Boat collapsed and died under him. Quinn has made an immediate impact in Hong Kong and completed a back-to-back double when Think Tank (5-1) took the Class Four, 1,650-metre fifth event for trainer Steven S. L. Leung. Quinn gave a particularly forceful display in the concluding stages as Think Tank came under pressure from Walk Big (4-1), but the gelding responded ably and began to clear away at the line from Over The Blues (14-1) who came home well along the rails to nip Walk Big in the last stride. It was a roughly run race early on but Think Tank, up in the van, escaped the trouble and was always going well. Said Quinn: 'I cannot possibly complain about the way things are going for me. 'I seem to be getting on some horses that are really going well and the winners tonight were cases in point. 'I am enjoying it a lot and I just hope it can continue,' said Quinn, who is likely to be a fairly solitary figure at trackwork in the coming week unless he can get a flight fixed up for a three-day holiday. 'I seem to have left things a bit late for that,' he said. And that's in distinct contrast to his well-timed race-winning efforts. Marcus, who is certain to be champion jockey following the upcoming retirement of Cruz, took full advantage of some head-strong riding tactics by others in the event when scoring well with William's Tact. Marcus brought William's Tact smoothly into the fray and ran right away with it in the straight. On his day - or night - William's Tact is a bit too good for Class Three but he has had his problems over the seasons.
