WHAT THE MAIN PLAYERS ARE SAYING:
“To have a horse run in the Golden Slipper and Cox Plate in the one year is pretty amazing, and to knock off a couple of Group Ones in between, it’s just been a once in a lifetime opportunity for most of us and we’re really enjoying it” -Yankee Rose’s trainer David Vandyke.
“Obviously Winx and Hartnell seem to be going really well, but she’s a weight-for-age 2000 metre winner in her own right in the autumn so you can’t dismiss her lightly, that’s for sure” – Lucia Valeninta’s jockey Kerrin McEvoy.
“She set a track record in the race last year. Physically she looks like she’s a little bit stronger so that gives me a bit of confidence to say we can at least hold our form. And then we’ve got to worry about where the challengers are coming from” Winx’s trainer Chris Waller.
“Winx is a deserving favourite. I don’t go into the race with any expectations, just focus on our horse and having him as good as we can get him on the day” – Hartnell’s trainer John O’Shea.
