Younger brother Noel still trains in NSW and has five Group 1s including his famous Stradbroke Handicap victory with Landsighting in 2000.
The 73-year-old Lawrie Mayfield-Smith is the longest serving trainer in Brisbane and only has a small number of horses in work at Doomben.
He has shown his loyalty by retaining jockey Adin Thompson.
Zouna is a $16 chance to smash the Group 1 ceiling for Mayfield-Smith behind $1.65 favourite Broadsiding.
Zouna cost $120,000 as a yearling and is stepping up to 1600 metres for the first time but that doesn’t faze Mayfield-Smith who would like a dry track.
“The distance won’t worry him and his father, Zousain, ran in this race and just got beaten and he’s very stoutly bred on the dam’s side,” Mayfield-Smith said.
