Buoyed by another breath-taking feature jumps win from Sea King in Australia last weekend, Rachael Frost is turning her focus to domestic stakes success at her home track at Otaki on Saturday.

Frost shares ownership of the Patrick Payne-trained Sea King, a resounding winner of last Sunday's Brendan Dreschler Hurdle at Ballarat, and prepares promising Swiss Ace filly Kate Louise, a contender for the Listed Courtesy Ford Ryder Stakes (1200m) for two-year-olds.

In three starts, Kate Louise has twice finished second and in between was sixth in the Listed Castletown Stakes (1200m) at Wanganui after getting too far back in the running.

She closed well for second at Hastings last start over 800m, beaten a length and a quarter, an effort that convinced Frost she was worthy of a start in the Ryder Stakes.

"If it was another 200m the other day, she would have been a hell of a lot closer. I'm not saying she would have beaten the winner, but she was hitting the line strongly," Frost said.

"This is a big step up, but even if she could finish third or fourth it's black-type which makes her more valuable as a broodmare later on. She handles it wet so that might just be her edge."

Frost has had to be patient with Kate Louise, who has her quirks leading up to raceday.

"She gets quite anxious before raceday. She knows what's coming and she won't eat before her races. She starts pacing and gets fidgety," Frost said.

"She's a lot better than she was and hopefully with the quicker backup between races, she won't think she's got a race coming up. It's funny though because she's a different horse at the racecourse. Once she's there, she goes to sleep."

Frost will also produce Redefine at Otaki, the Captain Rio three-year-old gelding chasing a fourth straight win in the Graham Sheldon Smellie Memorial (1200m).

"I'm not that keen on running on a heavy 11, but it could be a means to an end because there's a race for him at Te Rapa the following week. He could run in the 85 1400m there if he wins or the 75 1600m if he gets beaten," Frost said.

Meanwhile, the Grand National Hurdle (3900m) at Sandown on Saturday week looks the likely next target for Sea King, who continued to etch his name among the greats of jumping with his Dreschler Hurdle win at Bendigo.

He was denied a run in connections' preferred option - the Mosstrooper Steeplechase - because he had not trialled over bigger fences in Australia this season but it made no difference.

"He's pretty good isn't he?" Frost quipped.

"It was pretty impressive, considering it was a hurdle and they do go quite a bit quicker. They ran six seconds quicker than the steeplechasers. He won well and never really looked in trouble."

Frost said the Crisp Steeplechase (3900m) at Sandown the same day as the Grand National Hurdle was the preferred option for Sea King, but there were no trials scheduled before that race which would force their hand.
