Royal Delight, who finished a brave third to Sacred Kingdom in the Cathay Pacific Hong Kong Sprint in course record time, broke down in trackwork at Sha Tin yesterday morning and was later destroyed. Royal Delight was preparing for the HK$4.5 million Centenary Sprint Cup (Group 1) on Sunday week and was coming towards the final 200 metres of a 1,200m gallop with stablemate Famagusta when he suddenly went down. Trainer Caspar Fownes said despite the fact Royal Delight was taken from the track in the horse ambulance, all efforts to save the smart sprinter had been unsuccessful and he was put down by one of the Jockey Club's veterinary surgeons. 'Unfortunately, the leg was broken in three places, there was nothing that we could do for him,' Fownes said. Royal Delight, who was unbeaten in three starts in Sydney when known as War Of The Worlds, had won another three races since being bought by Peter Law Kin-sang. Royal Delight's biggest win was in the Premier Bowl, a Group Three race over 1,200m at Sha Tin on October 21, when he clocked a course record time of 1:07.6 for 1,200m. That record was subsequently bettered by Sacred Kingdom in the International Sprint Trial the following month. However, he earned even more kudos for his third to the world's number one sprinter, Sacred Kingdom, in the Hong Kong Sprint on December 9, when beaten 23/4 lengths. Fownes was attempting to focus on something more positive last night and spoke optimistically of Law's four-year-old private purchase Jackpot Delight, who is primed for a much better race in the Group One Mercedes-Benz Classic Mile on Sunday. 'He'll have the gear changes - a ring bit and the blinkers - and Darren Beadman has agreed to ride him for us,' Fownes said. Jackpot Delight was forced back to the barrier trials by stewards in the wake of a terrible performance at his last start, when he finished 13th of 14 runners behind Firm Offer over 1,400m at Sha Tin on December 26. 'That run last start was totally out of character, but I believe he's a very good horse and will show us something close to his true ability on Sunday,' he added. 'I think the gear changes will make a big difference and I was very pleased with the way he went in the new gear in his barrier trial.' Fownes is hoping to bring an early conclusion to a horror run of luck at his happy hunting ground, Happy Valley, tonight. The champion trainer has saddled up 56 beaten runners since his last success with Nirvana at Happy Valley on December 12. The yard has a number of top prospects this evening, including debutant Ocean Wide in the first, I'm No Square and Viva Fighter in the third, Mega Bullet in the fourth and Prime Target in the last.
