Among the opposition today will be Gr.1 Two Thousand Guineas (1600m) runner-up Dawn Patrol and last start stakes winners Qiji Express, Weaponry and Emily Margaret.
"Obviously it is a lot tougher than what he has met in his first two starts, but I think he is up to it. We have got to give him a chance at stakes level and he has got a nice draw in barrier four.
"Troy Harris knows him well, so I will leave tactics up to him, but he generally jumps pretty well from the gates."
After failing the vetting process to race in Hong Kong, Vigor Winner is likely to be a long-term member of Brennan's team, however high-profile stablemate Sword In Stone has been sold and will be doing his future racing in Hong Kong.
Raced by Singapore-based Englishman Paul Hickman, Sword In Stone was placed in all three of his New Zealand starts, including an eye-catching maiden win at Ellerslie and a narrow third placing in the Gr.2 Waikato Guineas (2000m).
The son of Redwood was ultimately left languishing as second emergency for the Gr.1 NZ Derby (2400m) after not amassing enough prizemoney. "You've got to expect these things when you're training in NZ," Brennan said. "The big buyers are overseas and it was an offer that Mr Hickman couldn't refuse.
"I'm still getting over him not making the Derby field. It was frustrating more than anything and I knew we had a horse that was going to be competitive and he had drawn well which made it even worse. It is one of those things. He was a late starter who didn't run as a two-year-old, so he couldn't get that prizemoney."
Meanwhile, Brennan also has one more target in mind for hardy sprinter Magnum, who finished seventh to star galloper Melody Belle in the Gr.1 Waikato Sprint last month.
"We are just freshening him up and getting him ready for the Flying Handicap at Palmerston North," Brennan said. "It's a race he won last year and that will probably be his last start for the season."
