Exciting young sprinter Divine Prospect (5-2 favourite) kept Australian trainer David Hayes narrowly in front in the fierce battle for this year's championship with a solid victory in the final event at Happy Valley last night. Hayes went into the meeting one winner ahead of defending champion and arch rival Ivan Allan and saw that disappear in the opening event when South China Way (9-5 favourite) romped home under Douglas Whyte in the longer sprint for griffins. Neither trainer played much of a part in the succeeding races but the Class Two nightcap had been pictured as a crunch race with Divine Prospect representing Hayes and Allan saddling up course and distance specialist, Perfection (9-2). But Divine Prospect, with champion jockey Basil Marcus up, made full use of his barrier one draw and hit the ground running. He scampered over the 1,200 metres and was never under a real threat of defeat. The official margin was 1.25 lengths to Yellow River (9-2) with Super Bomb (18-1) and bottomweight Sumotori (25-1) dead-heating for third. The leading duo now go into Saturday's big Epsom Derby night meeting at Sha Tin with Hayes on 55 winners. It was a bittersweet night for French ace Eric Saint-Martin, who left with a win, a demotion and a second placing. The runner's-up berth was on Dragon's Pal (5-1), considered one of the night's better bets. Saint-Martin, who saw the inside of the inquiry room too often for comfort in the first part of the season, blotted his copybook in the second race when Warm Winter (9-2), first past the post, lost on objection. Although the objection and official inquiry lasted for over 10 minutes, there was little surprise that Hara Hara (3-1 favourite) was given the race after being severely hampered inside the final 150 metres. Saint-Martin came across the Brett Doyle-ridden Hara Hara, forcing the English rider to snatch up and lose conservatively well over a length - the official margin recorded when Warm Winter crossed the line at the finish of the Class Four, 1,650-metre event. Hara Hara, who takes a few strides to really gather momentum, was forced to start it all over again and was gaining on Warm Winter when the line was reached. The decision was justified and favourite punters let out a roar of delight when the numbers were reversed. Doyle was ending a drought stretching back to 53 rides in dramatic circumstances but said: 'We were just getting into top gear when we were stopped in our tracks. I had no hesitation about objecting.' Things took a distinct turn for the better when Saint-Martin staged a first-to-last effort on Valley-loving Mabrouk (7-1) in the fifth event. Mabrouk was whipping them in as the Class Five field came to the run up the Rock in the 1,650-metre event and not too many clutching win tickets on the David Oughton-trained five-year-old would have been exuding confidence. Golden Era (25-1) was going great guns in front but weakened dramatically in the closing stages as Saint-Martin produced a grandstand finish to win by a head from Shining Winner (25-1). Saint-Martin was widely tipped to score on speedy Dragon's Pal (5-1) in the Class Three short sprint but bottomweight Master Merlin (18-1), ridden by claimer Patrick P.H. Tse, prevailed to take the honours. Also ending a mini-drought was long-serving trainer Lawrie Fownes, who led back Sky Manna (9-1) after the fourth event. Club jockey Danny Nikolic gave a faultless display in rating the winner in front in the 1,800-metre Class Five event. He slipped further clear on straightening leaving favourite Smart Dragon (6-1) and Godspeed (12-1) to chase him home unavailingly. Alan Munro has had a quietly successful season and is ending it on a high note. He had Just For Pleasure (5-1) perfectly placed in the run and swooped on straightening to claim major honours in the Class Four third event over the longer sprint. There was a cosy length back to reliable Valley sprinter Plentiful Harvest (10-1) with topweight Happy Going (8-1), in much easier company, finishing third. Favourite Hero's Choice (5-1) was fourth having had every chance.
