Magic Wand has collected the first Group One victory of her career, by landing the Mackinnon Stakes at Flemington.

The Aidan O'Brien-trained filly was running just four days after her 10th place finish in the Melbourne Cup.

"She's a very good filly," Ballydoyle's TJ Comerford said after the race.

"That was her third run since we got to Australia, but that was probably the first time she really got her ground. It's very unusual coming here that we weren't going to get quick ground.

"That's the quickest she's ran on since we got here.

"Aidan always said she was a very good filly. She's been placed in all those Group Ones and now she won one today. She's very tough - she ran two miles the other day, she ran in the Cox Plate and now she's won today.

"You won't find many that will do it like her, but Aidan seems to pull it out all the time."

Jockey Ryan Moore also hit the mark in the Group Three Queen Elizabeth Stakes as he teamed up with Willie Mullins' True Self.

"A winner is always better than finishing fifth or sixth in the Melbourne Cup," Mullins said of True Self, who is likely to run in the Hong Kong International Vase next month.

"She's improving, it's extraordinary. She's six years of age but she was jumping out of her skin.

"My son bought her out of a bumper in England for jumping and she arrived in my yard and I took one look at her and said, 'I hope you don't own that'.

"And here we are now, we've brought her down and she's given us a winner - it's extraordinary.

"I never dreamt she'd be a flat mare and I don't think anybody did at a time."
