Flemington trainer Danny O'Brien will be out to win his second Emirates Stakes with Valedictum who will be contesting the Group One feature for the fourth successive time on his home track on Saturday.

Now an eight-year-old, the Umatilla gelding won the 1600m Emirates in 2005, finished third to Divine Madonna in 2006 and was fourth to 100-1 shot Tears I Cry last year.

The last horse to win the race twice was Seascay in 1994-95 while Heroic Stone (1965, 1967), Aquanita (1960-61) and Amounis (1926, 1929) also achieved the feat.

"He's been a great horse for the stable. He's continued to come up season after season," O'Brien said.

"He had 10 months off with a tendon injury after his placing in this race two years ago and did a good job to come back and run fourth last year.

"He's raced well again this spring and I do think he's still capable of winning at Group One level over a mile, but he needs the right run."

Valedictum will be ridden by Glen Boss and drew favourably in barrier 10 but will jump from nine if the four emergencies don't get a start.

The gelding has won once since last spring, in the Royal Parma Stakes (1400m) at Rosehill beating Master Magic and Theseo on a heavy track in April.

He was spelled after running sixth to Triple Honour in the Doncaster Hcp (1600m) on a heavy track at Randwick on April 26.

At his fourth run this time in Valedictum ran sixth to Alamosa in the Toorak Hcp (1600m) at Caulfield and topped off his preparation for the Emirates when finishing eighth to Hot Danish in the Salinger Stakes (1200m) last Saturday.

O'Brien has endured a frustrating Melbourne Cup week so far with Barbaricus beaten a nose by Theseo in the Mackinnon Stakes on Derby Day, Master O'Reilly an unlucky fourth to Viewed in Tuesday's Melbourne Cup, with Barbaricus finishing 19th and Gallopin choking down and failing to finish.

The Grahame Begg-trained All Silent, who won the Group Three AAMI Travel Insurance Stakes (1400m) last week, 2007 Stradbroke Handicap winner Sniper's Bullet, who ran a brave second to All Silent after jumping from the outside barrier, are among the hardest to beat.

In an open race, Epsom Handicap runner-up Bank Robber and Myer Classic placegetter Mimi Lebrock look good chances after drawing nicely in barriers seven and five respectively.

Cranbourne Cup winner Majestical and the Mark Kavanagh-trained Sea Battle, winner of the Group Two Jayco Crystal Mile at Moonee Valley on Cox Plate day, also have to be considered.
