Trainer Mark Kavanagh says the favourite Whobegotyou will have to come around the field from as far back as last to win Saturday's Group One $1 million Caulfield Guineas after drawing barrier 12.

Kavanagh certainly wasn't complaining about the draw and said he would not want to alter the Street Cry gelding's racing pattern going into a race of such importance.

"There's nothing wrong with barrier 12. He'll get back, he could be last early and he needs to come around them," the Flemington trainer said.

"The last two starts he's been trapped on the inside. I'd rather him out there where he can do his own thing.

"You don't really want to give away a start but that's just the way he races. He's happy to do that and we really can't change that pattern going into a Group One."

Whobegotyou has done little wrong in five starts to date for three wins and two unlucky efforts when second and seventh.

His latest effort, when he won the Bill Stutt Stakes (1600m) at Moonee Valley late last month coming from 12th after being shut away on the inside to score by 3-3/4 lengths, was a most impressive Guineas trial.

"The horses that do defy racing patterns are the ones you like to see and that was quite impressive I must admit," Kavanagh said.

"He's learned a lot from being trapped in there like that.

"He's on the way up and he's done everything right going into this race which is what you want.

"He hasn't run a bad race."

Whobegotyou will be out to emulate the likes of Red Anchor (1984) and Helenus (2002) who went on from winning the Stutt Stakes to take out both the Caulfield Guineas and the Victoria Derby.

Trainer Anthony Cummings is happy going into the 1600m Guineas with Duporth, who drew barrier 10, and said the colt showed he was back on track following a slight muscle tear with his last-start fifth to Mentality in the George Main Stakes (1600m) at Randwick late last month.

"He had a minor setback in the lead-up to that. He had a month between runs and was up in distance as well so him to do as well as that was a pretty good recommendation for him," he said.

"He's come through that race pretty well. He's galloped well here (at Caulfield) on Saturday morning and again this morning and he's in the mix.

"I think if he gets the luck from the barrier he can run in the first four and if he is lucky he can win."

The Red Ransom colt has won two of his six starts including a narrow victory after being blocked for a run in the home straight in the Group Two Golden Rose (1400m) at Rosehill two starts back.

"He's run in Group company all along which gives you an idea of what a trainer thinks of a horse's ability and his win in the Golden Rose was very good," Cummings said.

The Mick Price-trained Lord Tavistock, who drew barrier seven, will race in blinkers for the first time on Saturday after trialling nicely in them at Caulfield this morning.
