The Tim Butt-trained pacer is the closest thing New Zealand has to a representative in the race which has been scheduled to run before New Zealand Cup week for the first time this year.
The move has ruled out the big-gun Kiwi pacers such as Lazarus from contesting the group 1 $A200,000 ($NZ220,000) feature.
After Butt announced recently that he is to train in Australia, some would argue there will not be a Kiwi presence at all.
However, with Field Marshal's Otago blood flowing through his veins and his hot recent form, New Zealand can definitely still claim him as our own.
But yesterday's barrier draw has meant that if the horse is to win the Victoria Cup for Mosgiel Syd and Shona Brown, Field Marshal - who races as My Field Marshall across the Tasman - is going to have to be very good.
The 6yr-old prospects took a small dive not just when he drew the tricky back-row 11 barrier, and more so when Australian star Lennytheshark drew barrier 1.
The David Aiken-trained 8yr-old returned with a crushing win in the group 2 Smoken Up Sprint at Melton from the outside of the front line last week in a sizzling 1.51.9 mile rate which had ready to start favourite for the Victoria Cup.
His landing of the ace now means he is set to start as a hot favourite.
Field Marshal made up good ground to run second behind Lennytheshark in the Smoken Up, but faces an even bigger task to run Lennytheshark down this week given the draws.
The Victoria Cup could serve as a guide as to whether former New Zealand pacer Tiger Tara will return home for next month's New Zealand Cup, a race in which he was runner-up behind Lazarus last year.
The New South Wales-trained pacer is among a group of 20 horses competing for 15 final positions in the race.
Last year's third placegetter, Otago hopeful Titan Banner, could also take another step on his path to this year's race on Sunday.
The Graeme Anderson-trained pacer is among the nominations for the Methven Cup alongside fellow Cup fancy Dream About Me.
Weedons trainer Nigel McGrath has also nominated his Cup-bound pairing of Classie Brigade and Ears Burning for the group 3 race as well as another runner in Maverick.
