John Moore's handy sprinter Key To Success left Happy Valley yesterday with three straight wins and his name suddenly being spoken alongside that of Fairy King Prawn. Not that even his greatest fan was comparing Key To Success with the former top ranked sprinter in the world, but he did manage to erase the great gelding's course record from the history books after scoring in the seventh race over 1,200 metres. With Run And Win scorching along in front, the race was set up for a quick time and Key To Success (Anton Marcus) rattled home out wide to oblige - slicing 0.1 of a second off the track record previously shared by top graders Fairy King Prawn and Bumper Storm. 'Actually, he was lucky. He went up in the air at the start but finished in exactly the right spot in such a fast run race,' Marcus said. 'It wasn't how I intended to ride him but had he jumped as normal, he probably would have been stuck wide and found it hard to win the way the race worked out.' Moore said he had been surprised to see Key To Success back yesterday, but said the gelding had shown a turn of foot he found quite unexpected. 'It wasn't where I wanted him ridden but he's won well and his turn of foot - I didn't know he could do that,' Moore said. 'I think we have to regard him as promising. He's over all that roguish behaviour he displayed early and is so settled in his work in the mornings, I guess he could be on the up and up still.' It was the second leg of a Marcus double, after the South African had scored on Arabian Wager in the third for Gary Ng Ting-keung, who broke a run of 71 outs. Freelance jockey Simon Yim Hin-keung stood down for his last three rides yesterday, but had no doubts he would be fit for Wednesday's fixture at the city track. 'I was running to keep fit a couple of days ago and I've pulled a hamstring muscle which just started to bother me,' Yim said. 'It isn't anything serious, though.' Shane Dye also took an early exit yesterday after clipping heels past the winning post in the ninth event. He was left lying on the track and stood down from the final race feeling dizzy. Dye had earlier landed his first winner for David Ferraris when three-year-old Red Baron surged home over the top of average Class Four rivals in the fourth. 'Never going to win. He didn't really handle Happy Valley but applied himself once he got into the straight and ran over them,' Dye said of only his second mount for Ferraris.
