A vintage May drive helped the Greg and Nina Hope-trained pacer reel in Thefixer to win the $30,000 group 3 feature.
The victory meant the Rock N Roll Heaven 5yr-old would go to the paddock on a high note before he is prepped for a New Zealand Cup and Interdominion campaign.
A frustrating season meant A G's White Socks was in the winner's circle for just the second time this term yesterday.
The pacer had to settle for second placing seven times this season, with six of those coming via just a head or a nose margin.
"I was rapt for the horse and everyone today, he really deserved that," May said.
May landed A G's White Socks an early one-one sit, before settling him off a good speed set up by Thefixer and Alta Orlando, who duelled in the lead over the last lap.
The reinsman pulled A G's White Socks out for his finish on the point of the home bend, and he went whoosh.
"He really sprinted hard today - he has been doing that lately.
"That is the way we are going to have to drive him.
"He can really fly off the gate and he can do work, but when he is saved up like that he is even better."
Thefixer fought hard after leading and was denied by just a nose at the finish.
