Punters might not have warmed to the rarity of a Thursday night at Happy Valley but reigning champion trainer John Size is breathing just a faint sign of life back into the trainer's championship after rediscovering some form at an action-packed night on the city track. Weichong Marwing was struck down with illness early in the night, then star apprentice Matthew Chadwick was rushed to hospital for overnight observation after falling on the home turn in race seven, which left David Hall with a few options he didn't like for Chadwick's booking on Tchaikovsky in the last race and he scratched when stewards would not allow Darren Beadman to replace the junior. Size claimed a double with Rare Treasure (Jeff Lloyd) and My Home Town (Zac Purton) - his first at Happy Valley since November, 2007, and only his second there in the past four years. John Moore had looked home and dry in the championship race, but with Size making the midweek fixtures count for something more in recent weeks and Caspar Fownes continuing to chip away, too, the race now has a faint pulse. Moore also struck last night with Fortune Haven (Darren Beadman) to hold his championship lead at a significant eight wins but he is being made to earn it. Rare Treasure's return to some form at his first time around the Valley has probably set the gelding's path in the immediate future as the very talented but brittle gelding has 'just not been letting down at Sha Tin' according to Size. 'He tore part of a foot off soon after he got here and he's had problems with his feet ever since,' he said. 'He is probably never going to show us what he could have been. He's a six-year-old soon and still only had a few runs and he's probably past the point of being able to throw it off. That little bit of rain in the past day probably helped, because he did let down tonight and sustained a long, strong run.' My Home Town gave Purton a thrill, as it was his first winner for Size, and the trainer was quick to praise the ride. 'It was crucial that he got around Cannonise at one point there on the circle or he'd have been stuck there, but he gave it a great ride,' Size said. 'This horse has not been able to draw a gate all season until tonight. I know he won at the 1,650m but he ran in that because frankly there wasn't much else on and I'm sure he's a better sprinter.' The Jockey Club was made to work for its money last night when it came to crowd and turnover last night, with executive director of racing, Bill Nader admitting that the Thursday experiment 'didn't muster.' 'Our two biggest Happy Valley meetings last season were Thursday meetings, so we thought we couldn't just let that go without further testing when we had the chance to program this replacement meeting for one we missed in March,' Nader said. 'But it hasn't really worked.' Brett Prebble and Douglas Whyte went head to head again on the night after missing each other a couple of times lately and paradoxically, Whyte came off second best despite having the better night. He managed a double on Butterfield and Dragon Boy, while Prebble landed just one win on legend for Hall, but the Australian's minor placings through the night saw him just touch Whyte off the for the Jockey Challenge honours. Chadwick was reported by the club to have avoided any serious injury in his fall, with he and Marwing still both under a cloud for Sunday's meeting.
