JOCKEY Sam Clipperton hopes that a change of environment can help Group 1 winner Rivet to a first Hong Kong victory when he makes his Happy Valley debut in the Class 2 Waratah Handicap (1650m) on Wednesday night (4 July).

Rivet, a winner of the Group 1 Racing Post Trophy (1600m) at Doncaster in 2016, is yet to place from 10 Hong Kong starts.
