Trainer John Size made an early start on the defence of his championship at Sha Tin last night, opening his winning account at the third meeting of the season, then reiterated that things would not be easy for him this term. In winning the championship last season, Size did not even have a starter until the fifth meeting, so last night's Kwangtung Handicap Cup victory with Dr More, having Shane Dye aboard, probably counts as an early win for the Australian. 'Yes, I stood them up a big start last year - wouldn't want to be trying to do that all the time,' Size quipped. Talented but tricky, Dr More swept around the field from near the tail of the Kwangtung Handicap Cup field then charged clear to win clearly if not easily over Sun Shine River. 'You see in this horse the problem that my team has got with the handicaps,' Size explained. 'I mean, he won tonight but he was off 110 in the handicap and now he will go even higher. We were lucky enough to find a race tonight that he was able to win but it doesn't get any easier once they get up there. That's much the same story for all the horses I had winning races last year - they've got to a high enough mark to make winning difficult.' Dye took Dr More back to the rear last night to overcome the Danehill gelding's habit of over-racing. 'He seems to race best that way - the last time he won, that was how he was ridden and he does settle better,' Size said. 'The speed wasn't bad tonight and he settled okay. Caracoler came out in front of him on the turn and made things a bit more difficult for him but nothing Dr More couldn't handle. I just hope we can find another race that he can win.' The win gave super sire Danehill a big night, after victories with the Ricky Yiu Poon-fie trained pair of Laser Glory (Henry Tsang) and Sprinter (Howard Cheng), and his grandson Wise Choice, by Danasinga. Yiu's opening winner, Laser Glory, brought up a family double for the week after the gelding's younger brother, The Duke, won at Happy Valley on Wednesday night. 'The Duke is a more precocious sort of horse than this guy,' Yiu said. 'Although he is a year younger, The Duke has got everything together early, while Laser Glory has taken time to come on.' Laser Glory's owner, Tse Cheung-lun, bought the gelding himself as a yearling and chose the rider last night. 'We tried to get Weichong Marwing but he had a commitment and I asked the owner who was his next choice,' Yiu said. 'He said 'Henry rode him last time, why not leave him on then?' so we did and he didn't make any mistake. The horse had worked well and I thought he might have improved a bit during the summer but after the way he had raced and trialled up to now, it was hard to be too confident.' Yiu said he planned to step Laser Glory up from last night's 1,200-metre distance, possibly as far as 1,600 metres during the season, and he has his eye on longer trips for Sprinter as well. 'He is out of a Shirley Heights mare so he is bred to get longer distances,' Yiu said after Sprinter had defied a wide run to win over 1,600 metres in the sixth event. 'This horse is quite a nice young horse on the way up but he is still quite timid,' he said. 'That's why he runs away from other horses but he will lose that as he gains experience. He has done a good job tonight and I think he can only improve.' Francis Lui Kin-wai continued his great start to the season when Plenty Of Surprise (Vincent Sit) and Tumbler (Douglas Whyte) won consecutive races to give him a double and five wins for the season already. Plenty Of Surprise made a good impression with his win after spending most of the race rounding the field wide, Lui's greatest fear before the event. 'I think he's an up and coming horse but I was worried about the wide barrier,' he said. 'But when Wise Choice won from a wide barrier in race two, I told Vincent to ride this horse just the way Eric Saint-Martin had won on Wise Choice. Not to worry about the barrier, but to try to get the horse to relax and then save him for the final part of the race.' Plenty Of Surprise outgunned Straight Win to notch his maiden win at just his second run and the son of Kingdom Bay has more in store. 'He should run further than the 1,400 metres,' Lui said. His other victor, Tumbler, came back to win at 1,000 metres after being tried at mile trips last campaign but Lui still believes he will make the grade at that distance. 'Tonight he was fresh, so he was able to come back to the 1,000 metres,' Lui said. 'The problem for the horse is that he can only sprint for a very short distance so he should be better suited by longer and he will head back to longer races as the season progresses.'
