Sizzling has firmed from $2.50 into $1.80 with TAB Sportsbet to win next Saturday's TJ Smith Plate at Eagle Farm after winning the G2 Sires' Produce Stakes.
The Snitzel colt opened $6 for the race when betting opened on May 1.
Trainer Kelso Wood warned his star two-year-old will only improve over the mile next Saturday.
Boban, who was impressive winning last Saturday, looks the biggest danger to the favourite.
Ninth Legion, a strong winner at Warwick Farm, was slashed from $41 into $10.
