"Cliffsofmoher, he's melting like an ice-cream at the moment", Freedman said as the horses took to the track.
The Irish horse had earned more than $1.7 million in prizemoney.
The Flemington track improved from the heavy to the soft range by the time the Cup was run but Appleby remained in the dark.
Fan favourite Red Cadeaux, who finished second on three occasions, was pulled up in the final straight of the 2015 edition of the race and it was later confirmed he suffered a break in his left foreleg. Hind limb injury caused 17 deaths.

Appleby, who said Godolphin's first Melbourne Cup win would only increase their hunger to win the great race again in future years, paid Kerrin McEvoy an enormous tribute for the win.
In a statement the RSPCA said there was a growing number of Australians who felt uncomfortable watching horse racing.
UPDATES: THE horse that exited midway through the Melbourne Cup - the Aidan O'Brien-trained The Cliffsofmoher - has been euthanased.
"I was lucky enough to get a license five years ago and a few people asked me what two races I would like to win for Godolphin and thankfully I've just knocked the second one out in respect of the Derby and Melbourne Cup", Appleby said.
The Chairmen and Directors of the Victoria Racing Club (VRC) later extended their sympathies, with Flemington Racecourse tweeting their condolences, "To the Williams family and the connections of The CliffsofMoher, which was euthanised after he went amiss in the Melbourne Cup".
UPDATE: THERE are reports the horse injured in this year's Melbourne Cup, Cliffsofmoher, has been put down.
Every first Tuesday of November is marked for the Melbourne Cup date, and Melbourne Cup history has spanned centuries.
Parties galore are also in store across Perth, some of the biggest being held at Market Grounds, Henry Summer, The Stables, The Bach Club and, of course, Crown Perth, which past year hosted 24,000 WA racing fans on Cup day and expects even more today.
