The five-year-old bay horse, trained by Hughie Morrison in Berkshire in England, has come in for increased attention since flashing home to be sixth behind Boom Time in the Caulfield Cup.
Marmelo had the fastest sectionals — times for the last 200 metres — in the race, covering the final furlong in 11.79 seconds.
The British horse had already caught the eye with a solid win in one of the key Cup lead-up races in Europe, the Prix Kergorlay at Deauville in France in August.
