WHAT THE KEY PLAYERS ARE SAYING:

"We're very aware that some Sydney horses struggle at Caulfield for the first time but we'd already thought about that six weeks ago. He's done a lot of galloping left-handed and this morning was just to give him a look at the lay-out of the track and get familiar with the place" - The Autumn Sun's trainer Chris Waller

"He rolled out some good sectionals late and he'll enjoy the step up to the mile while the soft draw will help" - Mr Exclusive's trainer Matthew Brown

"Hopefully he'll quicken away around the corner and put a margin on them and hopefully The Autumn Sun can't run him down" - Native Soldier's jockey Ben Allen
