Kieren Fallon voiced concerns as to whether the Emirates Melbourne Cup on November 7 will be run to suit Yeats.
While the Ascot Gold Cup winner has his own track rider, Gosuke Motoki, Fallon has been keen to ride him in his recent work and feels the five-year-old partner is blossoming Down Under.
“I think he’s enjoying being in Melbourne,” said Fallon, after the pair enjoyed a spin on Sunday.
However, having watched the former John Dunlop inmate Tawqeet win the Caulfield Cup on Saturday, Fallon added: “The way they seem to race here is not going to suit him because he needs a strong tempo all the way.
“He’s not the sort of horse you can stop and start like they do here and I won’t be riding him that way.
“No wonder they can run in the Caulfield Cup or that race on Derby day (the Mackinnon) and then back up in the Melbourne Cup because they hardly have a blow-out.”
The Irishman hopes to ride plenty of trackwork at Flemington in order to grow accustomed to the track prior to the two-mile contest.
Fallon will also partner California Dane on Saturday before getting the leg up on Churchill Downs in the Ascot Vale Stakes on Flemington’s Derby Day.
While Yeats is on course to take up the challenge for the Ballydoyle operation, the participation of many other high-profile British raiders remains in doubt.
Godolphin’s promising five-year-old Imperial Stride was forced to miss his planned prep run in the Caulfield Cup after sustaining an injury on the eve of the race.
He now looks unlikely to make the main event.
While a second scan conducted in the near future will determine plans, Godolphin representative Alan Byrne has not given up hope just yet.
“It’s unlikely, but he’s not lame, so we’ll wait and see what shows up in the scan,” Byre told www.theage.com.au.
Carte Diamond, unraced since finishing ninth in last year’s Caulfield Cup, could still conceivably make the starting line-up.
Veterinary stewards of Racing Victoria last week unanimously declared the entire’s troublesome tendon would not stand up to the Melbourne Cup test and ruled Brian Ellison’s charge out of the "race that stops a nation".
Ellison disagrees, however, and after jockey Danny Nikolic moved to support the Malton-based handler having partnered Carte Diamond in trackwork last Friday, the handler has asked for a second opinion.
“I know the horse isn’t lame. He’s as sound as a bell,” he told the Herald Sun.
“I know there is a problem, but I don’t agree he could break down.”
Australian owner Paul Makin hopes to be doubly represented by the Luca Cumani-trained pair Glistening and Soulacroix.
The former is pleasing connections but finds 35 other possibles ahead of him in the ballot order, while running plans for the latter are currently up in the air.
Sara Cumani, wife of Luca, described Glistening as “being on the right road” after he cantered at Sandown in Australia on Sunday.
He had been considered for Wednesday’s Geelong Cup but connections elected to keep the son of Sadler’s Wells fresh for the Melbourne Cup.
Explaining the decision, she said: “We find you get one shot at these races and I know Mr (Dermot) Weld did it.
“But he’s a genius and we find that it is hard to get a horse to peak twice.”
While a minor hoof problem prevents Soulacroix from taking up the Geelong Cup challenge, it is unlikely to keep him out of action for long.
He could reportedly make the first start of his antipodean excursion in either the Moonee Valley Cup on Saturday or get a taste of the Flemington turf in the Saab Quality on Derby Day.
