The man who bred and sold Black Caviar, All Too Hard and their $2.6 million half-sister appears to have hung on to a classy galloper for himself.

Rick Jamieson, the owner of Black Caviar's mother Helsinge, could have a genuine Derby prospect in Philippi who claimed his second win from as many starts in the Sportingbet Handicap (1500m).

Philippi ($11) displayed all the credentials of an emerging stayer, coming from well back to steam home over the top of his rivals to score by three-quarters of a length from Carringbush Jack ($15) with the favourite Forget ($2.20) the same margin away in third.

"He's bred to run 2000 metres, but I think he'll get to the Derby distance," said winning trainer Mick Kent.

"He's a bit backward but he's got the right temperament, nice and relaxed."

Philippi's slow development led to him making his debut only two weeks ago.

But he indicated the extra time had been beneficial, scoring impressively at Mornington and then making further progression before Saturday's race.

Jamieson, who races horses around the world and also owns the Gilgai Farm stud in central Victoria, has a barn full of well-bred mares, led by Helsinge, arguably the most valuable broodmare in Australia.

Among his biggest wins was last year's Australian Oaks with Absolutely and now has prospects of adding a Derby to his list of Classic victories.

Jamieson is also likely to keep Helsinge's next foal who will be a full relation to Black Caviar.

Kent said he would make up his mind on a Derby campaign after Philippi's next run in an 1800m three-year-old race at Flemington.
