Rosehill trainer Gerald Ryan has won many Brisbane winter carnival races, but he can't think of a more important one than Spill The Bean's victory in the Group Two QTC Cup at Eagle Farm.

The Aquis Farms syndicate, which won a race earlier with new buy Cradle Me, has completed a deal with Arrowfield Stud to purchase a 75 per cent controlling interest in Spill The Beans.

Aquis has bought the previous Patinack Stud complex at Canungra in the Gold Coast hinterland.

The three-year-old was well backed in to $4.40 favourite and held off Federal ($7) by a head with another long head to Stratum Star ($10) in third.

Ryan believes Spill the Beans could have gone on to win some good races up to 1600m but believes the colt will make a nice sire.

"He is off to the stud on Monday, so that was the last run for us," he said.

"He has the right breeding being by one of my favourite sires in Snitzel and his dam is also well bred.

"Her third dam is the dam of Bounding Away and Glastonbury, so that is why I thought if we took the blinkers off he would get out to 1600m."

Ryan said he couldn't remember the last time he didn't train a feature race winner during the Brisbane winter.

"But I also can't remember one which was important as this. His form was good with two Group Three wins but a Group Two really puts him up there," Ryan said.

Winning jockey Tim Clark said Spill The Beans hadn't been helped by the leader Eloping stopping quickly.

"I got left in front a bit too soon and he did weaken a bit but he was entitled to," Clark said.

Sam Clipperton who rode Federal said the gelding hadn't been among the best to begin but finished as fast as any runner.

Likewise Brad Rawiller, who rode Stratum Star, said the gelding was doing his best work at the finish.

Queensland mare Miss Cover Girl loomed a possible winner at the 200m but peaked near the line to finish fourth.

"She was set for a 1200m race last week which was washed out. Going into a 1300m race with three weeks apart just told," said trainer Kelly Schweida.
