Brett Prebble went around on also-ran Full Pack in the Lung Hang Handicap on the all-weather, but winning trainer Michael Chang Chun-wai was giving him plenty of kudos for the remarkable victory by Mutual Friendship. 'Credit where it is due - Brett was the one who suggested that I should try Mutual Friendship on the dirt last season after he barrier trialled him,' said Chang. Until then, he had trouble winning races but now he's had a Class Four win in May and this today in Class Three in only five starts.' Chang told Matthew Chadwick to ride Mutual Friendship quietly early and even he must have thought the top apprentice had overcooked the dinner when he was six lengths behind the main body of the field in the middle stages of the sprint. But so quickly did Mutual Friendship accelerate at the top of the straight that Chadwick nearly found himself running onto the heels of eventual third-placed Trulli before getting to the centre of the track to finish the job.
