A Cox Plate tilt for Grandslam?

Grandslam is likely to contest this year's Cox Plate with connections set to pay the late nomination fee for the weight-for-age championship.

The brother to star Jameka is likely to be the only three-year-old in the race, and heads there on the back of a tough third in last Saturday's Caulfield Guineas.

A jockey has yet to be booked for the race.

David Eustace, who trains in partnership with Ciaron Maher, said running in the Cox Plate with a light weight was too good an opportunity to pass up.

"He is a colt, he's going to have a very light weight. He rolled along well in the Guineas out in front, which is a tactic he can use again with that low weight if he draws well enough," Eustace said.

"You are only going to get one crack at a Cox Plate with that sort of weight on your back.

"The boss said straight away after the race that he'd love to have a look at the Cox Plate, made the enquiries on Sunday and Monday and we've got the inclination he'd be considered for it.

"He has made drastic improvement this prep and we think he will improve again fourth-up."

A Cox Plate run would cap off a meteoric rise for Grandslam, whose only victory to date is in a 2YO Benchmark 66 in South Australia.

Interestingly, Jameka had won just one race before claiming the Vase over 2040m on Cox Plate Day.

Both had also placed in their respective Guineas before competing on Cox Plate Day.

And that's not where the comparisons end.

"There's similarities in form and there's similarities in how they are physically. She is a bigger horse than him, but they are of similar shape, similar presence," Eustace said.

"We can only hope he ends up as good."

Grandslam is currently a $41 chance with Sportsbet for the Cox Plate.
