Merlin is the favourite for the $75,000 Breckon Farms Final and has looked the fastest of the early-season juveniles but has drawn outside main rivals Seve and Beckham.
"I don't think we need to worry. They are nice horses but I have beaten Seve both times we have raced him and if we can get some cover I think my horse will have too much speed."
Butcher says nothing went right for Art D'or last week but she can redeem herself with the potential to lead in race four.
Major Perry has had an unusual prep for the Derby, finishing second in the NSW Derby three weeks ago but missing his hometown prelude last Friday.
"I think the one [Beach Ball] will probably lead and then the rest of us will settle in single file until somebody moves but that could put me on the back of Akuta, which will suit me."
