Australian colt Shamexpress has failed to shine on the international stage, finishing ninth in the Group 1 2013 King’s Stand Stakes (1000m) at Royal Ascot.
The Newmarket Handicap winner appeared to be building a case for a big finish when he loomed up at the 400m mark.
But the final dash shown when winning the Newmarket would not be repeated as he faded and dropped out of contention in the closing stages.
British gelding Sole Power took top honours, narrowly edging out race favourite Shea Shea in a nail-biting finish.
Plans are now up in the air for Shamexpress who was originally scheduled to back up in the July Cup at Newmarket next month.
O’Brien told media in the UK it was too early to make any decisions but said he will assess the horse in the coming days.
“When I expected him to put in his bid, he had reached the end of it,” O’Brien said.
“We’ll have to assess him and see what we’re going to do.”
In what was a huge flop on the opening day of the Royal Ascot Carnival, odds-on favourite Animal Kingdom failed to measure up in the Group 1 Queen Anne Stakes (1600m) despite being spruiked by plenty as unbeatable in the race.
The Dubai World Cup winner never featured in the finish, labouring to finish in 11th position.
Trainer Graham Motion said Animal Kingdom, who is 50 per cent owned by Australian John Messara, is now likely to be retired to Arrowfield Stud in New South Wales.
“I would say that is probably it for the horse,” Motion said.
“At the half mile [800m] pole the jockey started to ask him to run and there wasn’t much there.”
