For a horse with just three starts to his name, Good Mood carries a turbulent history but the Derek Cruz-trained gelding added a win and a potential ban to his repertoire yesterday. Perhaps the searing heat was the last thing he really needed, but the gelding whooshed home from near last to win the opening race under Howard Cheng, then did what he has done at each race -finished utterly distressed. At his Happy Valley debut last February, Good Mood got into a fine state in the parade yard and lashed out, smashing a plastic rail, then collapsed after finishing seventh. Cruz brought him back once more in May when the Spectrum gelding tailed out in a race at Sha Tin and again returned in a distressed state. And yesterday the fact that he won the race made no difference, as he was the first horse pulled to a stop after the post and Cheng feared the worst as he turned him back towards the stands. 'I thought something had happened to him. I thought he was going to die,' Cheng later told the media, and Good Mood was already under veterinary care when the winning photo was taken. The vets declared Good Mood a victim of heat stress, which was not altogether unreasonable in yesterday's warmth, but stewards took a dimmer view of the incident. Probably only the fact that Good Mood had won prevented Jamie Stier's panel recommending his compulsory retirement, but Cruz was forewarned that retirement will be their recommendation to the Board of Stewards if Good Mood continues to pull up in the same fashion. 'He's a very sensitive sort of horse,' said Cruz, who has put up a fine training performance to bring the gelding's natural talent out despite his problems. 'I did a few things to try to switch him off mentally because he gets very stirred up and he has won today but I'll give him another break now. 'It's a shame, because he has ability and is a very nice mover. But the heat didn't help today and I'll have to look now at running him at the night meetings perhaps or waiting until the cooler times of the season. I'm hoping he will settle down more as he matures.' It was a double for Good Mood's owner, George Mok Yuen-chee, who also shares in the ownership of Cruz's Happy Valley victor on Wednesday night, Reward. While jockey Cheng was momentarily unsure of the fate of his first winner, he had no such trouble when he made it a double on Great Sensation for Eddie Lo in the fifth. Having his first start for Lo, the former Peter Chapple-Hyam-trained gelding was highly impressive, registering his maiden win over the 1,800 metres course. With Chapple-Hyam returning to England at the end of last season, Lo was the beneficiary when Great Sensation's owners needed a new trainer and the gelding won with some comfort yesterday, eased down by just under two lengths.
