“Her half-brother De Little Engine was superb at a mile-and-a-half, her mother was superb at a mile-and-a-half and when she was trucking at the 600, I thought, ‘This is going to be fun’.
“She’s a very, very nice staying prospect and I’m sure it won’t be her last decent win. Every time we sort of run at this distance she’s going to be very hard to beat.”
The victory seals an incredible week for O’Brien, who trained Australian-bred four-year-old Vow And Declare to victory in Tuesday’s Melbourne Cup.
“The two real horses we thought would measure up for us Cup week were Vow And Declare and her and they’ve had three runs here and won them all,” he said.
“I’m thrilled for the filly, she’s a filly we’ve had real high hopes for and we’ve all been looking forward to this day and fortunately it’s all come off.”
O’Brien added it was “special” to combine with Oliver for the group 1 win “who has been with me through the good times and the bad.”
Oliver said O’Brien, who he worked with a long time ago at Bart Cummings’ stables, was in incredible form.
“He learnt from a master I must say, but Danny is very meticulous in his planning and he’s proven that this week,” the champion hoop said.
“Certainly when he sets a horse for a target he gets them there in the right shape and he’s done that again today. It’s great to be part of a good team with someone you’ve known for so long.”
After Oliver overcame some poor pre-race manners from the filly, he said Miami Bound raced beautifully throughout her first go at 2500 metres.
“Once I found the back of Vegas Jewel I was pretty comfortable in the run,” he said.
“I still got left there a fair way out but felt that I was on the right horse to do it, but when you’re on that three-year-old first time at the distance that far out, you’re hoping nothing’s going to come out and get ya.”
John Ramsden-trained Never Listen finished more than three lengths back in second, with the Mitch Freedman-trained filly Moonlight Maid running on for third.
“She’s an aggressive filly and we had to give a bit of a start away to get her to switch off. I thought she was really gallant to the line,” Moonlight Maid jockey Ben Melham said.
Gamay and Vegas Jewel, who were also in the market, finished fifth and sixth respectively.
“She ran OK. Probably didn’t quite see out the trip,” Ryan Moore, jockey of Gamay, said.
Jordan Childs said he just couldn’t find cover on board Vegas Jewel.
“We took a punt and tried to go forward. Just couldn’t get in,” he said.
“She’s done a good job this prep and should be back better.”
