Douglas said Giga Kick had come off and extended break due to injury along with other niggles which had affected his first-up record.
A trip to Caulfield Heath for a barrier trial, running second to Lightning Stakes opponent My Gladiola on January 29, showed Douglas the old Giga Kick was back.
"The other day, he was pumped up, excited to be there," Douglas said.
"He began fast and I haven't seen that in him for a long time, and he's run well up the straight on numerous occasions.
"He won there at two, he won the Danehill Stakes at three and he's won a Champions Sprint, so I don't think it will be a problem on Saturday."
A field of eight is set to run on Saturday with three-year-old's making up more than half the field.
Douglas is banking on Giga Kick's experience being crucial with only six three-year-olds winning the Lightning Stakes in the last 25 years.
There was a spate of four three-year-olds winning in six running's from 2000 through to 2005, before Home Affairs scored, by a lip, from Nature Strip in 2022 which was followed by Coolangatta the following year.
This year the three-year-olds are headed by Group 1 winning colts Tentyris and Beiwacht while the fillies will be represented by Mahroona, My Gladiola and Military Tycoon.
"He might not have a great first-up record, but he's had the perfect prep leading into this," Douglas said of Giga Kick.
"It's going to be a good race, for sure."
