Costa entered Gold Ambition for the Open Handicap (1630m) and the Class Three Plate (1630m) but has elected to keep the gelding in restricted class for his Saturday racing debut in Queensland.
The now six-year-old gelding scored an impressive win at a Doomben midweek meeting recently when he came from last at the 600m.
It was only his third win in 36 starts after previous victories in a Warwick Farm midweek race in April, 2015 and a Bathurst Class One in January last year.
Baker recommended Gold Ambition go to Costa who formerly trained at Warwick Farm.
“It was a matter of getting Gold Ambition's confidence back and getting him to the right distance,” Costa said.
Jockey Scott Galloway will again ride Gold Ambition and he is predicting a bright future for the gelding.
“I think he can win a handy middle distance race here,” he said.
Galloway and Costa had plenty of success last season combining for 22 winners and believe the new season can be even better.
