The Greg Eurell-trained gelding goes around in the Silver Bowl Final, a 1600-metre event for three-year-olds.
The son of Toronado became a leading contender for the Silver Bowl after victory in a heat on June 20, which followed a second placing at Caulfield on May 30, performances that Eurell was relieved to see given what he produced at his previous two starts.
Obvious ran last at Sandown on April 6 and again at Mornington 12 days later and Eurell attributes a freshen as Monomeith Stud for his late-season revival.
"It was hard to work it out, he led into those runs in his usual manner and then he just failed to fire a shot," Eurell said.
"So we thought we'd give him a freshen up and send him down to Monomeith on the water walker.
"Then we just brought him back in and we're doing a bit with him, gave him a jumpout, the jumpout was good, so we thought, 'oh well, we'll go again."
