ODDS-ON favourite Mr Vitality (5-8) failed in his bid to land successive Centenary Cups, but trainer Ivan Allan was still at the presentation ceremony following the second leg of the annual Sprint Championship. Horse of The Year Mr Vitality finished fifth behind stablemate Quick Action (16-1) in the 1,000-metre dash, and provided French ace Eric Saint-Martin with the first leg of a back-to-back double. Although there had been whispers about Mr Vitality's preparation before the race, the public still weighed in, and late in betting his odds dipped into the red. But it was Irish sprinter Quick Action, given a perfectly timed ride by Saint-Martin, who eventually got the better of speed machine Debonair (9-1) who split the field up with his searing early pace. Michael's Choice, the 3-1 second favourite, did not take to the sprinting game and finished fourth without ever looking a winning chance. Allan said: 'Mr Vitality had a fever 12 days ago and missed two important days of work. It interrupted his schedule and affected his form.' Quick Action, who has a good record down the straight course, was about the only horse in the field who looked capable of pegging back the tearaway Debonair when the half-way mark was reached. And that he did, surging through close home to go on and win by three-quarters of a length, with three lengths back to third-placed Basic Instinct (25-1) who came home off the fast pace. Trainer David Hill said: 'Debonair has done us proud and he may have just one more run this season. I knew he would give them plenty to do and we almost got away with it.' Michael's Choice finished fourth and trainer Patrick Biancone will not be sending him sprinting again. 'It was worth taking the chance with him this time but that is the finish of it. I do not want to sour him for other races and I will probably only give him two more starts this season. 'There is a mile race in the middle of March and another set weights race over the same distance in April. He will go for both of those and that will be enough,' he said. Saint-Martin's double was completed in the following race when Medic Star (16-1) came out on top in a desperate duel with Super Horse II (8-1), and Wonderful Winners (5-2 favourite). The official margins were two short heads and it was a gripping finish. Mediocrity set a sizzling pace but Saint-Martin had Medic Star in a position to challenge when they weakened, and his decision to keep the leaders firmly in his sights paid dividends. South African star Piere Strydom, who is enjoying an excellent spell at the moment, chalked up his 20th winner of the season when topweight Born To Win (7-2) took the second griffins' event on the programme. Born To Win showed the benefit of experience and came home strongly to account easily for Diamond And Gold (10-1) who, like the winner, has had several juvenile starts. They proved far too strong for evens favourite Benji Storm, who weakened for fourth in the 1,000-metre event, while Happy Monies (3-1) finished third.
