Sheer Madness was scratched from a race at Sandown on Wednesday as connections sweated on a start in Saturday's Diamond for which the gelding is the $101 outsider.
Part-owner Frank Salanitri, who is assistant and racing manager for his brother John, believes Sheer Madness can run well getting ou to 1200m.
Sheer Madness finished fifth over 1000m in the Blue Diamond colts and geldings Preview and ninth in the Prelude over 1100m when he raced without luck.

"It's a very competitive race but his two runs have suggested that he's certainly up to them."
