Royal Symphony's first defeat cost him Caulfield Guineas favouritism but trainer Tony McEvoy has kept his faith in the smart colt.
Royal Symphony lost his unbeaten record when he finished fourth to Perast in Sunday's Group III Caulfield Guineas Prelude (1400m), which convinced Sportsbet to post Catchy as the new Caulfield Guineas favourite.
Catchy was also beaten on Sunday when third in the Thousand Guineas Prelude and McEvoy said the pair simply got too far back on a track that wasn't helping the backmarkers.
"Catchy got back and couldn't win today and he (Royal Symphony) got back and couldn't win," McEvoy said.
"From where he was on the turn to where he finished, I think it was a real pass mark, but not to the standard we are used to with that horse.
"He has pulled up fine and I was very happy with his condition after."
McEvoy said Royal Symphony also found the 1400m too short but he would also try new gear on the son of Domesday after he laid in under pressure in the straight.
"I think he's crying out for further and maybe tinker a little bit with some gear with some blinkers or winkers.
"Those colts can get into habits and it's my job to stop that from happening.
"He was the best colt coming into today and even though he was defeated today, I still believe he's the best colt."
McEvoy has until October 14 to get Royal Symphony right for the Caulfield Guineas.
