Winning Group One races is not new to Gai Waterhouse but her ninth Flight Stakes win has marked a first for her new training partner Adrian Bott.

Global Glamour ($5), a filly raced by an international syndicate of women, defied the $2.05 favourite Yankee Rose by half a length after taking Saturday's 1600m race by the scruff of the neck.

Yankee Rose was promoted to the head of the market following the withdrawal of Omei Sword because of a respiratory infection.

Waterhouse let Bott take centre stage after the race and he admitted he was somewhat overwhelmed by the Group One feeling.

"It's sensational," Bott said.

"It's an incredible feeling and there are so many emotions going through me.

"It is hard to describe. It is a very good feeling and one I will cherish forever."

While Group One wins are not new for Global Glamour's jockey Tim Clark, it had been 3-1/2 years since since his last victory at the top level.

"It's been a while." Clark said.

"My last Group One was in Hong Kong on It Has To Be You."

Clark said the addition of a barrier blanket had helped keep Global Glamour calm before the race and she had travelled well for him.

"The start was all important today. It was a masterstroke by Gai and Adrian to put the barrier blanket on her. It helped keep her calm," he said.

"She began pretty well and in the small field I was able to control it.

"Even though she was still going a bit keen within herself through the run she wasn't going that quick. It allowed her to have a great turn of foot.

"I knew it would take a good one to run me down."

Blake Shinn expected that good one to be Yankee Rose but she didn't accelerate as he expected.

"I had a pretty good run throughout and thought I was close enough approaching the turn," he said.

"I was waiting for that electrifying turn of foot that she can possess. She was a little one-paced at the top of the straight but she was great through the line."

James McDonald rode third-placed Sezanne who finished two lengths behind Yankee Rose.

"She went brilliant," McDonald said.

"She gave me a lovely ride. She's definitely a filly probably for the future but she's gone very well."
