Leeton father and son combination Robbie and Wayne Sullivan were told Cee Cee Ambro wouldn't make it after developing a split growth in a front fetlock joint as a weanling.

However after seeking more opinions she underwent treatment before going on to race at group level at two, three and now four after booking her place in the Regional Championships final at Riverina Paceway last Friday.

"She has done a pretty good job as when she was a foal she was a cripple and they told us to put her down," trainer-driver Wayne Sullivan said.

"We persevered, got another opinion and they've got her pretty much fixed up.

"She still has issues with her feet but for someone who wasn't meant to race on she's done a pretty good job."

Cee Cee Ambro has won nine of her 26 starts, with another 11 placings, and over $110,000 in prizemoney.

The mare was group one placed in the NSW Breeders Challenge final two-year-old fillies before taking out the Breeders Challenge Blue final last season.

Her heat win was her first in eight races this season and Sullivan is much more hopeful than confident of his chances on Friday.

"She's come through the run pretty good and put a solid effort in the other day but will need to be way above that to be a contender," he said.

"She is also pretty honest, she has a few racing traits that I don't like but if you end up back in the field she will race them all the way home to fill the back end of the placings but she is a few grades below a few of them."

Sullivan will take back the gig after Blake Jones timed his run just right in last week's heat.

Sullivan drove the mare when she finished fifth behind We Salute You in the first round of heats but after struggling with a bout of food poisoning elected to hand over the role.

While still struggling with the effects, he's hoping to be right for Friday's final.

"I've had a pretty ordinary week but hopefully it will get better over the next few days," Sullivan said.

The mare has drawn barrier nine.

Sullivan also has Tactical Response in the major consolation.

He finished second behind Western Sonador in the first round of heats, beaten 16 metres, but didn't look to go one better to make it through to the final last week.

His form was franked with Mister Donald, who finished behind him qualifying last week.

Sullivan thought the second tier race would suit better.

"All things being even he couldn't be in amongst them in the final so it was a good option for him to just be in the consolation," he said.

"He will go alright in that too if he gets the right draw and the right trip he won't be too far away.

"He beat (Mister Donald) quite comfortably from behind the other day and he kicked on a won quite good so he will be a chance in his race."
