Todd Harvey admits he may have got it wrong with Scamandrius at Belmont last fortnight.
Scamandrius ran sixth of 13 to In Plane Sight when trapped wide throughout the 1400m event.
Harvey was keen to test the Helenus gelding after finding the money in three of his first four outings.
At Pinjarra last month he settled back before finishing powerfully to win by 1 ¼ lengths over 1400m.
Scamandrius and his jockey Clint Harvey will step out from barrier two in the field of 16 for Wednesday’s twitter.com/Perthracing Handicap (1400m).
“He looks well suited from the draw and dropping back a little in class,” said Harvey on Racing Radio’s Big Breakfast.
“On reflection it was probably a mistake to run him last time out.
“It was throwing him in at the deep end.
“Dropping back to Wednesday grade and from the draw he looks awfully hard to beat.”
Stable mate Izademon hasn’t been sighted in five starts this campaign but showed improvement at his previous appearance over 2000m at Belmont on August 8.
The chestnut gelding was near eighth when turning the corner before running on to be placed fifth and 1 ¼ lengths from Sheikrattle’n’roll.
“It was a much improved run and his best this preparation,” said Harvey.
“It was an indication he was getting back to his best.
“He meets an even bunch of stayers and on his best form he is more than capable of matching it with them.
Izademon, a winner of two races from 18 starts with three minor placings, will contest the Sky Racing Handicap (2100m).
He will jump from barrier ten for Clint Harvey.
