Noel Mayfield-Smith's fondness for Famous Seamus is transparent and if his opinion of the multiple stakes winner is correct, those feelings are set to grow.

The five-year-old took out Saturday's Listed City Tattersalls Club Lightning Handicap (1100m) at Randwick for the second consecutive year, making light of his 59kg to put a comfortable three-quarters of a length margin on Ichihara.

Mayfield-Smith said a winter campaign in Brisbane has proved the making of Famous Seamus and he is adamant the gelding's best is yet to come.

"He just did so well up there. He's a bigger, stronger horse. He's more settled and his times are much quicker," Mayfield-Smith said.

"The other morning I let him run up on the bit and he's run his last furlong in 10.25 (seconds). How many of them can do that?

"The only thing that worried me (today) was the small field and the difference in weight."

It is the handicapper who will prevent Famous Seamus continuing his current campaign in Sydney.

Mayfield-Smith confirmed he will look for a short-term target in Melbourne, but longer term he hopes to give the gelding another shot at the Stradbroke Handicap in which he finished unplaced this year after losing a shoe midrace.

"I still think his best time is to come, autumn and winter," Mayfield-Smith said.

Confidently backed into favourite from $3.70 to $3.30, Famous Seamus had his rivals covered a long way out and while Ichihara ($3.80) was game she was no match for the winner.

Rarefied ($9) made ground for third, two lengths behind the runner-up.
