The classy three-year-old won the $1.5 million AJC Australian Derby by a length and a quarter ahead of second place finisher Retrieve and third-place-getter Anacheeva.
Retrieve put in a gallant run down the home straight but it wasn’t enough to beat Shamrocker, who put her neck in front and never looked back.
The last filly to win an AJC Australian Derby was Research back in 1989, and today Shamrocker showed the boys that she has the goods to finish on top.
Trainer Danny O’Brien feels that this distance is best suited to Shamrocker’s ability.
“I think you really saw the best of her here over the 2,400,” O’Brien said after the race.
O’Brien is now looking forward towards a possible Melbourne Cup start come the spring carnival.
“She’s just done a double that no one else has done the (Australian) Guineas and the (AJC Australian) Derby,”
“She loves Flemington and I’ve got no reason to think she can’t run the two miles.”
Jockey Glen Boss has now ridden Shamrocker to four victories from just five rides.
“Gee she was good to me today this filly,” Boss said.
“This is an absolute thrill, on my favourite track in front of my favourite people.”
Boss was confident that Shamrocker would perform in the AJC Australian Derby after having had the chance to ride her in trackwork earlier in the week.
“I was extremely confident after trackwork on Tuesday,” he said.
