Gai Waterhouse will be banking on a mix of youth and experience when she looks to build on her late-season momentum at Rosehill on Saturday.

Waterhouse returned from her annual European holiday to take training honours at Warwick Farm last Saturday with a winning treble.

She again appears poised to play a strong hand at Rosehill where she will start a trio of runners in the Listed Winter Stakes (1400m) including early favourite Under The Sun.

The four-year-old has been racing in great heart with a win and three seconds at his past five starts, including a stakes placing behind Mic Mac at his most recent outing.

He will be joined by a pair of seasoned stablemates who Waterhouse believes are both capable of testing their younger rival.

Kontiki Park, a rising eight-year-old, and Kinnersley who is rising seven are at $11 and $26 respectively.

Group Three-placed last spring, Kontiki Park will be lining up for the third run of his campaign following a second-up fourth over 1500m when he lumped 60kg.

He drops to 57.5kg on Saturday, is a three-time winner at the trip and appreciates rain-affected ground, unlike Kinnersley who Waterhouse admits needs drying conditions.

"They're both going super," Waterhouse said.

"Star Thoroughbred's Kinnersley is evergreen. He just needs this sort of weather and a drier track to be competitive.

"And I don't think there is an older horse going better than Kontiki Park.

"It looks a super race for him."

Waterhouse is considering backing-up last Saturday's Warwick Farm winner Charing Cross in the Hungry Jack's Handicap (2000m), although she will make a final decision closer to race day.

"He looks terrific and I love backing up my horses," she said.

Juvenile Bull Point will be striving to atone for his last-start defeat as an odds-on favourite when he steps out in the opening race.

The Fastnet Rock youngster followed an impressive debut win with a second to the smart Eurozone at Rosehill.

He was tardy to begin both times but Waterhouse says that is all part of his learning curve.

"He is still learning but he's a lovely horse," she said.

Nash Rawiller is booked for both Bull Point and Charing Cross but despite Waterhouse having three Winter Stakes runners, her No.1 stable rider will partner Queenslander Bold Glance for rival trainer Norm Hilton.
