A younger brother to Switzerland will debut at Warwick Farm on Wednesday.

Just a couple of days after Switzerland started his new career, the former star colt's younger brother will make his debut.

Michael Freedman will take the covers off Decorum, who steps out in the $100,000 Super Maiden over 1400m that kicks off Wednesday's Warwick Farm card.

The Snitzel colt is the second foal from American mare Ms Bad Behavior, a daughter of Blame whose only other to race is Switzerland.

That son of Snitzel created headlines before he even raced, being a $1.5 million Inglis Easter yearling, before going on to win half of his 10 starts including last year's Coolmore Stud Stakes at Group 1 level.

Switzerland was retired after finishing unplaced in this year's T J Smith Stakes and on Monday started duty at Coolmore Stud, where he stands for a fee of $60,500.

TFI, which paid $550,000 for Decorum at last year's Inglis Easter Sale, will be hoping Decorum one day follows him into the breeding barn.

He doesn't look as sharp as his older brother but hit the line well off wide runs in two trials in July.

Decorum holds down the $7.50 third line of betting in Wednesday's race, behind Super Seth gelding Scoop The Pool ($3.40) and Tuscany ($3.90), who is a brother to Schwarz.

Also engaged is Joe Pride-trained colt Attica, a son of Lonhro who is the first foal from former classy Godolphin mare Savatiano.
