BRILLIANT French rider Gerald Mosse lit up Happy Valley when taking the final four events last night at combined odds of 1050-1. But only after he had survived a 10-minute stewards' inquiry following an objection by Walter Swinburn, rider of Gladstonian, who finished second to his Super Delight in the last. The head-on film confirmed the race-meeting stewards were spot-on in dismissing the objection and Mosse was allowed to walk away with his prized four-timer. He had earlier scored on Bruce Hutchison's Pretty Long Legs in the third event and then completed a back-to-back double for Lawrie Fownes on Crown Commander and Courageous in the fourth and fifth. Fownes was fulsome in his praise for Mosse's riding and well he might be as the former Patrick Biancone-retained jockey executed perfect waiting tactics in each case. Fownes said: ''This was Gerald at his best. He gave both my winners great rides to the extent he made it look easier than it was.'' The four-timer took Mosse to six winners in the territory and he's only been here for three meetings - two on his current one-month visiting rider's licence and the International Cup meeting prior to this stint. For Fownes, the double took him to 19 winners and cemented his position in third in the trainer standings. After a bright start to the season his horses have returned to form with a vengeance. Pretty Long Legs was Bruce Hutchison's fourth win of the campaign and the second time the son of Rory's Jester has scored at the Valley. He was contesting a modest third event where he benefited from the drop down into Class Four. He was always travelling like a winner. Watch out for Majulah Superstar from this race. He is improving and is beginning to look capable of scoring when pushed up in distance to around 1,400 metres. Basil Marcus and Ivan Allan kept up their assault on their respective riding and training titles when Horse Supreme defied trouble in running to eventually win the opening event going away. But not before supporters of the heavily-backed 2-1 favourite had suffered a couple of scares. The first came when Marcus had to check off the heels of the apprentice-ridden The Sure Thing and lose a good length-and-a-half approaching the top bend in this 975-metre dash. The second lasted until about 30 metres from the post with a revitalised and now well handicapped Winning Vic making a determined effort to lead start to finish. For Marcus, the dual defending champion jockey, it was win number 31 and left him six clear of his nearest pursuer Tony Cruz. Allan, who is away at the Australian sales searching for more talent, has now trained 28 winners. He is six clear of John Moore in his pursuit of his first Hong Kong champion.
