Trainer Tony Cruz was not ready to blame jockey Matthew Chadwick despite California Memory's defeat out of a place at odds-on in sensational circumstances in the Jockey Club Cup (2,000m). Drawing a low barrier for a change yesterday became a nightmare for California Memory as he finished fourth to Thumbs Up (Brett Prebble), Pure Champion and Irian (Darren Beadman) after spending much of the home straight looking for ways out of the maze created around him by rival jockeys. First Beadman, then Prebble kept California Memory fenced in behind runners - with Thumbs Up's shift inwards later earning Prebble a suspension for November 27 and 30 - and the grey had nowhere to launch his big finish. 'He never had his race - he was in traffic all the way up the straight,' said Cruz. 'Matthew had a lot of horse but no place to go. As far as I'm concerned, the horse would have won and lost nothing as far as the international race.' With connections disappointed in Chadwick's ride on the same horse in Singapore two starts ago, the question of whether he would be aboard for the Hong Kong Cup on December 11 hung around, and Cruz admitted there would be discussions. 'I know it's the second time, so I don't want to say much about it until I have a chance to sit with the owners, but I think there's a good chance that Matthew would still ride the horse,' Cruz said. Chadwick said he had opportunities to come out from inside runners, but they came too early in the race. 'The plan was to keep him covered until the straight, so I did, and when I wanted to go out I couldn't,' he said. 'He is only small and when I tried to edge Irian out, Darren put me back in. He was unlucky but he also didn't travel the same as he usually does - normally he pulls at the reins but today he was flat and off the bridle.' The favourite's defeat took some of the attention off Caspar Fownes' victory with Thumbs Up, who will tackle the 'mission impossible' against the European stayers in the 2,400m Hong Kong Vase. 'When Danny Shum trained him, his best run was over 2,400m when he stretched Viva Pataca - and I know if he can get a soft draw and just relax, there won't be a horse with any better turn of foot than Thumbs Up,' he said. 'He's had internal bleeding problems which have made him difficult to train but at the moment he is great, I can train him the way I want to and I want to get him out to an extended distance.' John Moore said Irian 'just blew up in the dying stages, which we feared he might'. 'He wasn't at his top for this and he bottomed out the last bit but he will be peaking on international day,' Moore said. Cruz was also thrilled with the effort of Pure Champion (Douglas Whyte) to finish second and hopes for a Hong Kong Cup invitation for the former Irish-trained horse. 'All last season, he had problems with mucus and with quarter cracks on his hind feet, but he's over that now,' he said. 'Douglas said that when Pure Champion saw daylight today he just took off and probably got to the front too soon, but he has only been run down near the post.'
