Champion trainer Tony Brett confirmed evergreen sprinter Glen Gallon will have his last race in next month's Topgun (525 metres) after a fighting second in the Dapto Megastar (520m) on Friday night.
The Queensland warrior threatened a boilover in Dapto's first ever Group 1, but couldn't reel in low-flying Victorian Peter Rocket in front of a bumper crowd. Another Victorian, Proven Nitro, completed an interstate trifecta.
Brett suggested Glen Gallon's effort was enough to earn a berth in next month's invitation-only Topgun at The Meadows - greyhound racing's version of the Cox Plate.
"The Gold Coast Cup in about two weeks' time [will be his next start]," Brett said.
"That's the plan and that [Dapto Megastar run] has just about got him into the Topgun, I think. That will be his swansong and that will be it."
Glen Gallon has amassed more than $600,000 in prizemoney in an illustrious career, including winning the 2012 Winter Cup at Albion Park.
He came within 1¼ lengths of adding another major to his resume on Friday night.
"I thought if he gets through on the rail he was a big chance, but the run didn't come," Brett said.
"I'm stoked to run second - he ran a ripper race."
So too did winner Peter Rocket, whose place in the final - worth $75,000 to the winner - was not confirmed until 48 hours before the race.
The Keith Hellmuth-trained speedster won a rough-house Prelude a week earlier but required around-the-clock treatment to be fit to contest the final.
Handler Lisa Hellmuth said the he would be aimed towards the Adelaide Cup next month.
"I just can't believe he came out and won," she said.
"The quality of dogs [is unbelievable] and anyone could have won it. I've been worried all week because he did pull up sore after his run last week because it was a bit rough.
"He's got the biggest heart and he just bores through the field ... He's the best dog you could ever own."
Peter Rocket began quickly from box two before railing underneath track specialist Double Twist at the first turn.
Glen Gallon threatened down the back straight, but could not reel in the talented Peter Rocket in the charge to the line.
