"He could bob up over Cup Week running in one of those staying races."
Hayes was not referring to the biggest race of all – the $10m Melbourne Cup (3200m) – with the Group 3 Queen Elizabeth Stakes (2600m) on Champions Day a more likely target this year.
The Western Front is coming off a second placing to Vegas Jack at Flemington on June 20, when he endured a tough run from the outside barrier, and Hayes is confident he can turn the tables with more luck in running.
"He probably had the hardest run in the race," Hayes, who trains in partnership with brother Will and JD, said of the 1-1/4-length defeat.
"He had no luck at all. He was wide the whole trip, had to work in the middle stages, hit the front early and just got run over late.
"But he's come through the run well."
The Western Front, who will be ridden by Daniel Stackhouse, meets Vegas Jack 1.5kg better for the last-start defeat and will jump from barrier six with Vegas Jack drawn nine.
The Western Front is $4.20 favourite and Vegas Jack at $7 with the pair split by mudlark Wuddzz, who is at $5.
