Exuberant is a $9 chance in the TAB's fixed-odds market, shading Sai Fah at $10.50, with Appellant at $23 in a market headed by debut winners Last Sight and The Tailors Niece at $4.
Marsh's other runners at Trentham are Bella Gioia, Mr Trump and Belle Fascino.
At Ellerslie, Loose Cannon will seek to enhance her claims for the Gr.1 1000 Guineas (1600m) at Riccarton on November 17, for which she is at $14 in the futures market.
"If she goes well here, she'll go to the 1000 Guineas," Marsh said.
"She had 10 days off after her last run but her work has been good and this race will clean her up nicely for Riccarton. Media Sensation is backing up from winning last week and she looks hard to beat in a pretty good lineup but our filly's form is good. If she had luck on her side she would have finished third to Advantage and Xpression [in the Gr.3 Gold Trail Stakes at Hastings] which would make her form look better.
"She nearly got put over the rail but she finished it off well and she's going well."
Loose Cannon was offered at $10 in the TAB's Soliloquy market behind Media Sensation at $3.50, Queen Of The Air at $4 and London Express at $4.20.
Marsh will also saddle other Riccarton aspirants at Ellerslie, with Gr.3 Christchurch Casino New Zealand Cup (3200m) hopeful Felaar and Gr.2 Coupland's Bakeries Mile (1600m) entry Ugo Foscolo joining Our McKay and King's Cross at the Auckland Racing Club meeting.
