The gelding had a strong winter campaign in Sydney before heading to Melbourne where he relished the 2800m under a perfect ride from Jamie Melham.
Mormona was only afforded a short break before resuming over 2000m at Caulfield and Rob Archibald said in an ideal world they would like more time.
But Archibald said the gelding was an out-and-out stayer and second-up up off a short break over 2500m would not pose a problem.
"Obviously from a timing point of view it's a little bit tricky as he'd been up a little while before winning at Flemington, so we knew that we had to give him a little bit of a freshen if we were going to get through to the spring," Archibald said.
"So, he had a bit of a let-up, spent a bit of time at the beach and now we're working our way back.
"He is a natural stayer, and he's come through the last run well.
"I thought he was excellent, and we couldn't have asked for anything more. He was back, and a bit wide, and we thought he closed off well in the circumstances.
