Australian jockey Dwayne Dunn continues to go from strength to strength and took his season's tally to 12 wins with his first Happy Valley double yesterday. And the Down Under connection was complete when the two wins were for his compatriot trainers, John Size (Mega-Fighter) and David Hayes (Victory Master). While Hayes is looking forward to next Sunday with five runners in the four International races at Sha Tin, Victory Master's Class Three success maintained his three-win lead at the top of the trainers' championship. Dunn used Victory Master's gate one draw and natural speed to hold the fence and all the aces in the seventh contest over 1,000 metres. 'This is a great bread-and-butter type of horse - the sort of horse that wins a trainer a championship,' Hayes said of Victory Master, whose three wins have come from his seven Happy Valley starts. 'I'm very fortunate to have a few of these sorts of horses at the moment. You look at this guy and Amity and Top Winner and a couple of others, and they are just great Happy Valley horses. They have speed, they don't make mistakes and they don't let you down. They are never going to be champions but they are triers and will win plenty of races around here. And they all add up at the end of the season. You can't win a championship on Group wins alone.' Sparingly raced Mega-Fighter also kept his Happy Valley record intact as his other win came at the tail end of last season on a wet track at the city course and his record now reads six starts for two victories there. Size has had Mega-Fighter in the stable for only a short time and was especially pleased to see him win the third event and take the trainer into double figures. 'It's great to win early with horses you've taken on. I was actually very happy with how the horse ran in his first start for me last week at Sha Tin,' Size said. 'As anyone could see from the stewards' report on the race, he did suffer some interference in the race. 'He protested successfully and was promoted from sixth to fifth and might have finished a bit closer if he had enjoyed a clear run.' Size was also well aware of the horse's past wet track form. 'Sure, I think he was possibly helped by the wet ground today but even without that assistance, I did think he had trained on well from the other day and that's why I was happy to back him up into this race after a week,' Size said. 'He has handled the quick back-up well and Dwayne gave him a great ride. He's riding everything very well at the moment and it was a big part of the win.'
