The Freedman brothers have continued their affinity with the progeny of first season sire Extreme Choice, producing Stay Inside for a powerhouse debut win at Randwick.

The colt was just the second juvenile Michael and Richard Freedman have saddled up in Sydney this season and both have won.

Tiger Of Malay, also by Extreme Choice, took out the Kirkham Plate for the stable in October.

Michael Freedman said it was a pity Extreme Choice had fertility issues, producing just 48 live foals from his first crop, as his progeny had shown good ability.

"I wish they were making a few more of them. We've had two two-year-olds to the races this season and they'e both horses by Extreme Choice," Freedman said.

"With Tiger Of Malay and this bloke, and we've got another couple at home, they've all got great actions so it's just a shame he's not as fertile as we'd all like."

Stay Inside showed early speed to camp off the leading pair before pouncing in the straight.

When Robbie Dolan asked for a supreme effort inside the final furlong, Stay Inside ($7) accelerated clear to put 2-3/4 lengths on Headliner ($5.50) with Ashema ($3.30 favourite) another half-head away.

Freedman said he had expected a competitive performance but was surprised the colt showed such dominance.

"We've always had a decent opinion of him. He probably hasn't been totally obvious but he's one of those two-year-olds that the longer he's been in work the better he has gone," Freedman said.

"He's in at the right time of year now and if he comes through today alright then we'll maybe aim a bit higher with him.

"He is very professional too. He hardly turned a hair here today which is always a good sign with these young colts particularly."

A $200,000 Magic Millions purchase, Stay Inside immediately firmed with TAB fixed odds from $101 to $26 for the Blue Diamond and Golden Slipper.
