O'Brien has strong hand in Alister Clark

Trainer Danny O'Brien can't split his trio of runners in the Group 2 Alister Clark Stakes at Moonee Valley.

O'Brien is looking forward to testing Eraset, pictured left, and At The Heads as potential Australian Guineas' contenders in Saturday's 1600m feature.

His other runner Take The Rap is not nominated for the Guineas, but connections have until March 1 to pay a $41,250 late entry free.

TAB Sportsbet rates Take The Rap ($7) marginally ahead of Eraset and At The Heads who are both $9.50 for Saturday's event.

The Lloyd Williams-owned Linton, who was scratched from Sandown on Wednesday, is the $3.40 favourite.

O'Brien said Take The Rap, who will be ridden by Craig Williams, would have a harder task at the Valley than last start when he scored a neck win over Encosta Belief and Alister Clark rival Extra Zero in the CS Hayes Stakes (1400m) at Flemington on January 30.

"He got the right run the other day but he has the disadvantage of being drawn the outside of the field this time," O'Brien said.

He warned against dismissing Eraset on his last run when fifth in the Hayes Stakes.

"It didn't work out for him last start when he was ridden upside down," O'Brien said.

"He has drawn barrier one and hopefully he can get a sit behind them this time."

James Winks will ride Eraset who, by Reset, has had six starts and before the Hayes failure won three races in row including races at Sandown and Moonee Valley.

Nick Hall rides the progressive Hussonet colt At The Heads who had a Ballarat win and city placings at Caulfield and Moonee Valley before his last-start victory at Sandown.

He has to make the biggest improvement of the three stablemates, but O'Brien believes he deserves his chance.

"It was a nice win the other day and this will tell us where we are at with him," he said.

Linton, who is also not entered for the Guineas, has raced only twice but heads the Alister Clark market after scoring a seven-length maiden win at Cranbourne on January 31.

Michael Rodd replaces Hall on the Galileo gelding.

O'Brien's top Guineas hope is Spacecraft ($26) who was a first-up third to Guineas favourite Denman in last month's Zeditave Stakes (1200m) at Caulfield.

At The Heads is at $61 and Eraset is $81 for the Guineas while another stablemate Rockferry, yet to run this campaign, is at $51.
