Quinn had to fight for every inch of ground and Sadian finally managed to force his way through to hold Secret Archive by half a length, with Winter Garden three parts away.
John Dunlop, Sadian's trainer, admitted that his charge had failed to impress.
The leading Cambridgeshire fancy Captain Scott will miss the race. The four-year-old was quoted at 16-1 by the Tote.
His trainer, Jeremy Glover, had issued a warning over Captain Scott's participation when the weights for next month's race were published last week and yesterday he said: "We haven't been able to get him right. I said he was doubtful when the weights came out and we've made a decision early because we don't want people backing him when he's not going to be ready in time."Reuse content
