One punter has ignored barrier statistics on the Blue Diamond Stakes and backed the Tony Vasil-trained filly Psychologist to win $140,000 in Saturday's $1 million Group One feature at Caulfield.

Despite Psychologist having to jump from the outside gate, 15, after Thursday's scratching of Tricky Tricky, the punter has outlaid $20,000 at $8, the biggest wager TAB Sportsbet had taken on the 1200m two-year-old race.

The Choisir filly, who made an auspicious debut when winning the Group Three Blue Diamond Prelude (1100m) for fillies by 4-1/4 lengths at Caulfield on February 6, drifted from $4.40 to as much as $8 since Tuesday's draw before coming in to $7 on Friday.

The $120,000 yearling purchase had been $101 when betting on the race opened.

In 39 runnings of the Blue Diamond only eight winners have drawn outside 10.

Two of those jumped from barrier 15 - Knowledge in 1997 and Redoute's Choice in 1999.

Vasil, who said Psychologist had the "wow" factor after she won the Prelude, can become only the second two-year-old to win the Blue Diamond at only her second start, Redoute's Choice being the only horse to do it.

Jockey Mark Zahra said Caulfield was not the worst track at which to draw wide from the 1200m as there is a straight run to the home turn.

David Hayes, who holds the training record with five winners, has a slight leaning towards Shaaheq as the pick of his trio even though the filly is the only maiden in the field.

Shaaheq, one of three runners by champion sire Redoute's Choice in the race, has run second at all her three starts but particularly impressed Hayes when she chased home Crystal Lily in the Blue Diamond Preview (1000m) at Caulfield on January 26.

"We resisted the temptation to run her in the Prelude. We were thrilled with her Preview effort and we think she's spot-on and the winkers on will only be a bonus.

"The thing about her is she ran the fastest sectional (last 200m in 11.44s) for the whole day at her last start. It's a big sectional."

Hayes said blinkers had turned Redoute's Choice filly Evidentia upside down since her run-on fourth to Star Witness in the Talindert Stakes (1100m) at Flemington on January 30.

"Instead of being ridden into the race we expect her to travel. We've purposefully kept the blinkers off until now waiting for this race," he said.

"Long-term she's probably going to be a very good miler (1600m horse)."

Hayes said he could not remember training an easier debut winner since he returned from Hong Kong than Encosta de Lago colt Legalistic who scored by seven lengths over 1200m at Sale on February 7.

"Whether it was the opposition, the wet track or he's very good we'll find out on Saturday," he said.

Trainer Peter Moody and jockey Luke Nolen are out for back-to-back successes after the victory of Reward For Effort last year with Tale Of The Cat filly Willow Creek.

The Paul Messara-trained Beneteau ($3.20 fav) would be the third son of Redoute's Choice to win the race following Undoubtedly in 2005 and Nadeem in 2006.
