Sydney jockey Sam Clipperton has added a Group winner to his successful first season in Hong Kong.

Clipperton took his tally to 39 winners with his victory on the John Moore-trained Booming Delight in the Group Three Lion Rock Trophy Handicap (1600m) at Sha Tin on Sunday.

"I'm thrilled," Clipperton told the HK Jockey Club. " And to do it for John Moore and on this horse, Booming Delight, too.

"He has been my favourite horse since he started racing here. I do all of his trackwork, I've ridden him in most of his starts.

"I got down to 116 pounds (52.5kg). It's a relief, but it's also a thrill. That's been the whole season, just amazing."

Moore said Booming Delight could be an ideal candidate for the Hong Kong Mile at the International meeting in December.
