Predatory Pricer's bloodlines will be the focus when he faces the starter for the first time at Canterbury on Saturday - as the half-brother to sprinter Takeover Target.

The Street Cry two-year-old has so far avoided the limelight with a low-key preparation under the care of Murray at Kembla Grange but is already showing similar traits to his world champion sibling.

"He tried taking a piece out of me more than a few times," Murray said.

"He is a big boy and likes things his own way. You could say he's got personality.

"I have heard similar stories about Takeover (Target) so it must run in the family," the trainer added.

Murray hopes there are other similarities to Takeover Target, who has won races in four countries and accumulated more than $5 million in prizemoney on the racetrack.

Preparing Predatory Pricer, given the pressures that come with a potentially $1 million racehorse, has been the biggest challenge Murray has faced in his short training career.

He has bided his time with the big chestnut colt, waiting until late in the season to produce him after two stints in the stable.

"The pressure was on to get him ready for the (Golden) Slipper but he just needed time," Murray said. "Remember Takeover (Target) didn't start until he was a four-year-old.

"Being his little brother he was always going to get plenty of attention, but I wanted to be sure he was ready for it," he added.

"The mare (Shady Stream) has thrown a few horses who have been winners, but Takeover (Target) is the only one who really could gallop.

"This bloke has shown he is a natural athlete and is sound.

"Blokes who have ridden him have been impressed but the real test will come if he starts on Saturday."

Predatory Pricer ran second in an open barrier trial during the equine influenza crisis and then won a two-year-old trial before a break.

Since being back in work from a spell, Predatory Pricer has won a jump-out to prove he was ready for raceday, but Murray will take a cautious approach with the two-year-old and vowed to scratch him if he draws poorly at Canterbury.

"I would have liked to start him at home and kept it low key, but there are no two-year-old races here," Murray said.

"This race was the only real option.

"It will give us a chance to see where he is at the moment but we are in no hurry with him - and if he draws out (wide), I will scratch him."
