John Size got tired of waiting for the rain and Bumper Bumper became impatient, too. Eventually it all became too much for the horse and trainer combination and a scrambling victory in the $1.6 million ATV Cup at Sha Tin yesterday was theirs. 'He's a very consistent racehorse - he wins his one race a year,' quipped the leading trainer after Bumper Bumper ($142) had held off the luckless My Choice (Brett Prebble) to score his first win since the May 21 meeting at headquarters last year. Bumper Bumper is a renowned soft tracker and Size deliberately held the five-year-old back this season, waiting for the back half of the term when, in theory at least, the rains arrive and the tracks get softer. The rains arrived all right, but they disappeared just as quickly and Sha Tin has been in a baked-down state for the past two weeks. Bumper Bumper, to his credit, raced on both those good-to-firm tracks and showed the tough aspect of his character at the same time to overcome the disadvantage. Bumper Bumper resumed only in February and last week's race was only his sixth for the season. 'You'd have thought we'd find a wet track for him by now, but by the looks of him he simply couldn't wait any longer,' Size mused. 'Giving him a race one week ago obviously woke him up a bit, because he got out pretty quickly today and was really keen to go on with it.' Jockey Chris Munce said he didn't have a moment's worry with the Success Express gelding, who speared out of gate 12 and moved across to race at the girth of natural front-runner Bobo Win. 'Young Terry [Wong Chi-wai] was pretty determined to lead on Bobo Win, so I didn't have any problem letting him go,' Munce said. 'In fact, it suited me. I knew I was on a very fit horse, having just raced last week, and he could make his own luck from there.' Luck was a commodity that Prebble had plenty of across the full spectrum of the afternoon, but not much of it was available when he required it on My Choice. 'It's just such a shame, I really felt for the horse not being able to win today,' Prebble said. 'I love this horse. If he was in Australia, I genuinely believe he'd be a Group One horse. He's so game and he tries so hard - today was his race to win but I just couldn't get clear running when I needed it. He's lunged at Bumper Bumper late, but hasn't made it.' Jockey Douglas Whyte was the target of some loud abuse from disgruntled punters after missing the start on even-money favourite Hello Pretty, but the champion jockey said later there was nothing he could do about it. 'He was just going backwards when the starter let them go and almost sat down, so he's missed it a good two lengths,' Whyte said. 'Then, I've met some interference at the 800m and got cleaned up again in the straight. 'There's no doubt in my mind he should have won,' the Durban Demon added.
