His Caulfield Cup jockey Ben Melham's confidence has been further buoyed after yesterday's draw.

"Everybody saw his run the other day and more importantly he's pulled up well," Melham said. "He's a horse who backs up really well so he's got a lot of things in his favour. And he's got a favourable draw now.

"It would obviously be very special to me. Especially to be able to do it for Aidan O'Brien and more importantly it would be a milestone for him."

Johannes Vermeer was at $5.50 before the draw, while Humidor remains second favourite at $6 after drawing barrier seven in the field of 17.

The 2015 Caulfield Cup-winning trainer Murray Baker has Australian and New Zealand Oaks winner Bonneval and Australian Derby winner Jon Snow in the race, with the pair drawing 14 and six respectively. After being the favourite before finishing sixth in the Caulfield, Stakes, Bonneval is now at $7 with Jon Snow at $11.

Despite a report after Saturday's unplaced Caulfield Stakes run that the mare pulled up lame, Baker said Bonneval seemed "perfect" and he didn't consider there was a problem at all after the weekend.

He said Jon Snow would be thereabouts near the pace from his draw while Bonneval usually gets back to the second half of the field.

"I can't pick between them," Baker said. "They're two different types of horses. One runs up there and the other is a backmarker, so I'll be happy to see one of them in the frame."

Along with Humidor, Victoria's premier trainer Darren Weir has Amelie's Star in the Cup and the mare is on the fourth line of betting at $8.50 after drawing barrier 13.

Weir was due to have three runners but Japanese horse Admire Deus, one of the leading pre-post contenders, suffered a serious leg injury in trackwork yesterday morning.

Naturalism Stakes winner Harlem has the inside barrier while Sir Isaac Newton has the widest gate.
