A group of internet chat line fanatics may have ended trainer Gordon Yorke's search for his next star sprinter following Nuclear Medicine's explosive win at Doomben.

The wet track specialist took his record to five wins and five placings from 12 starts after leading all the way for a commanding 1-1/4 length win in Saturday's Driver Recruitment Hcp (1110m).

"I'm not sure of the exact numbers but there's about 52 owners in this horse from all parts of Australia and they'll be screaming as far away as Perth," Yorke said.

"They were chatting on one of those internet chat lines when one of them asked the others if they wanted to race a horse.

"They went looking for the best trainer with the best strike rate and came up with me and asked if I would train a horse for them.

"I've got a five-year-old unraced half sister to this bloke and they're all involved in her as well.

"he also goes good and I'll be trialling her in about two weeks."

Nuclear Medicine, a son of Nuclear Freeze, was bred by surgeon Dr Tony Ethell, a long time client of Yorke, who hails from Coffs Harbour on the NSW north coast.

Yorke is on the lookout for his next stable star following last week's decision to retire boom sprinter Natural Destiny, whose career was cut short following a mystery leg ailment.

The five-year-old entire underwent exploratory surgery at Sydney's Randwick Equine Centre in February after an abscess developed on his near side fetlock.

Surgeons could not determine what caused swelling in the fetlock but Yorke believes a snake bite was responsible as his pet dog took ill and later died around the same time Natural Destiny's leg problem was discovered.

Natural Destiny's swollen leg was filled with congealed blood and although there was no tendon damage, it was decided he was too valuable as a future sire to risk on the racetrack.

Yorke is keen to repeat Natural Destiny's victory in the Group Three Healy Stakes (1200m) at Eagle Farm in 2006 when Nuclear Medicine returns for a Brisbane winter campaign.

"I'm just starting to put together a team for the winter and I'm looking for my next champion," said Yorke, who has 24 horses in work.

Yorke is hoping some of Natural Destiny's ability will run off on Nuclear Medicine during the winter.

"This horse flew with Natural Destiny to Melbourne when I took him down for the Salinger Stakes two years ago so he knows all about travelling," he said.
