Ed Walker’s filly had not been totally disgraced in top company this season, notably when third behind Hello Youmzain and Calyx at Haydock before taking fifth in the Commonwealth Cup at Royal Ascot.
Down in grade for the Group Three against her own sex, she was sent off a 6-1 shot against 15 others, but she was allowed to dictate matters from the front under Paul Hanagan.
With a furlong to run, Shades Of Blue came out of the pack to challenge Royal Intervention and it soon became clear only two mattered, with the previously unbeaten Archer’s Dream failing to pick up.
As the two fought it out and drifted over to the far rail, Royal Intervention just edged it by a neck, with almost four lengths back to Red Balloons in third.
“She was already a winner at Listed level last year and she’s got some Group Two black type as well, so to win a Group Three with her is great,” said Walker.
“We’ll see where we go next. She’s obviously got the speed for six, but I’ve always felt she’ll stay seven.
“I’ll put her in the Prix Maurice de Gheest to try to get some Group One black type, but that is obviously a big step up and might be ambitious.
“The other option is to take her to America and see if she stays a bit further there.
“I’m very pleased, she’s a very smart filly. She had a mishap in the middle of last summer, so it’s nice to get her back to winning ways.
“Paul doesn’t know the filly at all and she’s not very straightforward, so a lot of credit must go to him as he gave her a peach of a ride.”
