The Norman McCullagh-trained Crimson Vixen booked a spot in Wednesday's group two $67,000 headline race after finishing second in its heat with a time of 25.13 - the highest place-getter.

Monigatti predicted Crimson Vixen would lead at the cup, providing a major advantage.

But he said the Correy Grenfell-trained Orson Allen, which achieved the fastest heat time of 24.94, would most likely start favourite.

Orson Allen, which recently won the Horsham Cup and Cranbourne Cup, will pocket a $50,000 bonus if it takes out the Warrnambool fixture and completes a country treble.

Joining these two at the starting line will be Anthony Azzopardi's Whiskey Riot and Myniong and All, Steven Collins' Dyna Hunter, Andrew Paraskevas' Eye Got It and Andrea Dailly's Dyna Patty and Lucy's Milo.

Warrnambool's 450-metre track record is 24.72, set by the Brett Bravo-trained Unlawful Entry in April 2016.
