He started Saturday's meeting guiding Naantali to victory in the opening race before wins aboard Visao, Brave Song and Sixties Groove.
“It was a big day obviously,” Lane said.
“It's hard to ride four winners in a day anywhere so to do it at metropolitan level is very satisfying.”
Lane said he had ridden four city winners at Morphettville previously and believed the six-win premiership lead Williams had was too great.
“I'm more than likely going to go to Adelaide next Saturday to ride Nature Strip so that would be another meeting I'm not here for,” he said.
“But it's been a massive season for me.”
Trainer Darren Weir said Sixties Groove would need work on his racing manners to win a good race in Australia.
The Irish-bred import made it back-to-back Flemington victories taking out the KA Morrison Handicap.
Weir said there were of worrying signs as Sixties Groove ran down to the rail after striking the lead inside the final 200m.
“Hopefully there's nothing worrying him,” Weir said.
“He's got to learn to switch off early otherwise when he gets up in class it's going to be a lot harder for him,” Weir said.
“Once the race got sorted out he tucked his head under and relaxed and he got a lovely cart into the race and put them away, but he did lay in very bad.
“Going forward, he's a beauty.
“I'm not sure what we do with him but we'll have to head to a good race somewhere with him I guess.
“You can only beat what's there and he's done it well.”
“It's great to finally get my first city winner and it means even more to be able to do it on the big stage at Flemington,” Punch said.
