Online bookmaker Bet365 opened Zerprise Journey at $7 for the Benchmark 64 event over 1600m but that price was quickly snapped-up with a current top quote of $3.60.
Zerprise Journey has had two runs this time in and has been working home gamely over shorter journeys.
The step to the mile, barrier one and the 2kg claim for apprentice Krystal Bishop has made Zerprise Journey an attractive betting proposition.
It's no surprise that Robert Smerdon's two-year-old Instant Action has also met with support in the opening race.
Despite opening short at $2.50 punters have taken that price with $2.20 currently the best odds on offer.
Below are the significant firmers for Saturday's Morphettville meeting.
