Derby champion Murray Baker knows it isn't impossible to turn a poor dress rehearsal into a stellar main event because he has done it once before.
But therein lies the problem for Baker as he tries to turn around Cutadeel's last-start Avondale Guineas shocker heading into Saturday's $1 million Vodafone Derby at Ellerslie: of all the Derbies that Baker has won he has only pulled off the total form turnaround once.
"Mongolian Khan did it, he is about the only one," says Baker in his laconic way. "He went pretty poor in the Rosehill Guineas then came out and won the Australian Derby at his next start.
"But I've found in my career when they go below par in their final race before a Derby it is very, very hard to turn them around because you don't have a lot of time."
Not that the Avondale Guineas two weeks ago, by far the most important Derby lead-up, was a complete disaster for Baker and training partner Andrew Forsman.
