But Marsh knows he has Serious Satire going into this race in absolute peak condition.
"She has done brilliantly since Hastings.
"Every trainer would like a filly with her temperament -- she is absolutely gorgeous to do anything with. She has just the best nature.
"The only thing I don't like is the barrier draw [originally No12, but she will come in a couple of spots]. That can really count against her in a race this strong."
Last start Danielle Johnson managed to get Serious Satire into a good position in the one-out line. Because of the stamina index (Zabeel mother) Johnson has to niggle at the filly from the 550m, but she kept responding and got up to win in the closing strides.
It was the win of a filly desperate for 1400m and the 1600m of the Guineas.
Marsh also has Rocanto and Billy Mojo in the race. Rocanto could finish only seventh when resuming at Hastings, but Marsh warns about reading too much into that.
"He is the biggest improver in the stable.
"We've been battling blood issues with him, but everything is right in that area now.
"Billy Mojo was game winning last start and he has blinkers on this time." The field includes Hawkes Bay Guineas winner Amarula, Let Her Rip and Crutinize.
