KEY COMMENTS

"We couldn't really have her any better," said Rising Romance's co-trainer Tom Dabernig.

"It will be a little short of his best but I want to see him finish the race off and give us a good platform leading into the Caulfield Cup," trainer Kris Lees on last year's Melbourne Cup winner Protectionist.
