A training treble at Happy Valley was not Ricky Yiu Poon-fie's biggest day at the office but it was enough to put a smile across his face yesterday. 'I did come to the races today thinking I had a few chances and could maybe win a race or two but three is very nice indeed,' Yiu said. 'A few of my runners were well drawn and they've been racing quite well. They weren't surprises but three is always a bit to hope for.' It was by no means a stable record, as Yiu recalled having won four races in a day at Sha Tin in the past. South African rider Glyn Schofield is cementing a place for himself in Hong Kong's jockey ranks and continued his fine run by linking with Yiu for two of the three stable victories. Schofield piloted Amo (race two) and then the useful young sprinter Danhero (race seven), while Frenchman Olivier Doleuze provided Yiu's middle pin aboard Dragon Win. The double took Schofield to 18 victories this season and equal fifth with Gerald Mosse in the championship. Danzero gelding Danhero was just a green, erratic three-year-old last season but has come back a more mature character and athlete this term and yesterday's win made it two from two since the break. 'He is only young and still developing,' Yiu said. 'Just to look at him, Danhero is a much bigger, stronger horse than he was last season. He has grown fully, filled out and compared to then, he is a different animal. And he is more mature mentally as well. He was green and ran about last season but he is doing everything right now.' Yiu would not predict Danhero's ultimate level but made a good point about his form last term. 'If you think back, he chased home Winning Dragon here one day last season and that horse is a Class One sprinter now, so perhaps he can go higher yet,' he said. Yiu said Amo was able to turn his form around yesterday after the blinkers were removed. 'He's had them on for a couple of runs but they weren't doing him any good - he was just over-racing - so I took them off again,' Yiu said. 'I gave him a four-week break to freshen him up and today Amo raced a lot better. He had a nice draw and Glyn gave him a good ride through the race and his form at Happy Valley has been quite consistent. 'The draw is so important here with the C+3 course. It made the difference with Amo and with Dragon Win too. He is limited but he didn't have to do any work, got a nice position and it made all the difference in the tight finish.' French rider Eric Legrix, who rode Kashmac in the third event behind Dragon Win, stood down from his remaining rides with a stomach ailment. Legrix will be fit to ride at Happy Valley midweek.
