Hughie Morrison’s five-year-old has so far struggled this season, but it would be a mistake to scotch his claims in the main event of the four-day York fiesta.
It was always going to be impossible to land a blow in the Gold Cup at Royal Ascot on his seasonal debut, and he was predictably never a factor.
More worrying, perhaps, was his subdued run in the Coral Marathon at Sandown, which was followed by a similarly poor show at Goodwood.
But those prepared to give him another try can be rewarded, as there is a strong chance the shrewd Morrison has had the Ebor on the agenda all year.
The gelded son of Shirocco, it must be remembered, impressed in the staying department in 2015, with an 11-length demolition job at Salisbury last May a sign of what was to come.
Fun Mac then got to within half a length of Clondaw Warrior in the Ascot Stakes at the Royal meeting and also gave Pallasator a decent run for his dough in the Doncaster Cup.
Then there was his pleasing effort at Longchamp last autumn, when he finished third in the Prix du Cadran.
Stamina, then, is certainly not an issue when it comes to the Ebor, but he is not short of boot, either.
The forecast for rain is also likely to satisfy his connections as Fun Mac is just as good an operator on an easier surface as he is when it is rapid.
With the capable Charlie Bennett taking off a handy 5lb, the fact he is at an age which has supplied bountiful Ebor winners should also be factored into the equation.
Meanwhile, it is never easy finding the winner of the Irish Thoroughbred Marketing Gimcrack Stakes but Mokarris just about fits the bill.
