Chris Waller was the Caulfield Cup trainer with the most to win but even more to lose at Wednesday's barrier draw for the $2.5 million race.

In the end, he has no cause for complaint despite admitting he was thinking the worst for top fancy Hawkspur, Oaks-winning mare Royal Descent and his remaining runners Moriarty and Kelinni.

Just as he has two of the favourites in Hawkspur and Royal Descent and two of the outsiders with Moriarty and Kelinni, the barrier draw has also ensured his quartet is divided into pairs.

Kelinni has the rails with Royal Descent in gate three while further out Hawkspur has stall 16 and Moriarty barrier 18.

"I think, overall, the draw has worked out pretty well for us," Waller told AAP.

"When you are worrying about a barrier draw you think `what if they all draw bad'. Two of them did, which I've since seen positives from."

Uppermost in the thoughts of Waller - and backers of the long-time favourite Hawkspur - is the Queensland Derby winner's gate.

Jockey Jim Cassidy wanted to discuss the draw with Waller - but that was before the trainer thought it best to leave tactics up to the rider who is on the cusp of winning his 100th Group One race.

"I'm not going to interfere with what Jim wants to do," Waller said.

"He is the right horse who is tractable enough to be where he needs to be."

Which is a good thing for Cassidy who is chasing his third Caulfield Cup triumph 16 years after his first, which came with an all-the-way win on Might And Power.

"I don't worry about barrier draws because there's nothing I can do about them," Cassidy said.
