Pretty Gorgeous toughed it out at Newmarket to give Joseph O'Brien his second victory in the bet365 Fillies' Mile as a trainer.
Ridden by Shane Crosse - who should have been aboard the yard's St Leger winner Galileo Chrome last month, only to miss the ride after a positive test for Covid-19 - the Lawman filly got the better of Indigo Girl by half a length.
Pretty Gorgeous had missed her own intended target last weekend, as she was caught up in the contaminated feed issue that led to the O'Brien family runners being withdrawn at ParisLongchamp on Sunday.
The chief threat came from John Gosden's Indigo Girl, winner of both her previous outings including an impressive success in the May Hill Stakes at Doncaster.
Indigo Girl made ground seamlessly from the rear - but Pretty Gorgeous, who had been closer to the pace, then quickened away.
It was to Indigo Girl's credit that she made a second challenge, but she could only get to within half a length of the 5-2 favourite, with 50-1 chance Snowfall in third.
O'Brien had previously taken the race in 2018 with Iridessa.
He said: "It's fantastic and I thought Shane gave the filly a great ride.
"He was patient on her and committed when he had to. Shane is a young man, but he is a very good rider - strong and cool in a finish, and he doesn't panic. She was fighting them off at the line.
"She has got a great constitution. She went to France last weekend and came back. The lad that rides her out at home said she had taken the journey well and was in good shape, and all credit goes to them as they said she would come here with every chance.
"I was quite worried myself and I had a good conversation with Mr (John) Oxley during the week and he was keen enough that if she was in good shape that we would take the chance and let her run.
"The way it worked out the French race looked a tough race and the ground was nicer here. She has won her Group One and whether that was here or France, I wouldn't be fussy. It has worked out well in the end."
He went on: "She is an exciting filly going forwards. I would think (the 1000 Guineas) is the obvious target now. She has the options of the Breeders' Cup, but we will probably decide to put her away for the season.
"She is a Lawman, so she would not be bred to go very far. I think Lawman's can get 10 furlongs and I see her more as an eight to 10-furlong filly rather than an Oaks-type filly at this stage."
Of Indigo Girl, Gosden said: "It was a great run and I'm very happy with her.
"Her mother won the French St Leger and her sister won a Group One over a mile and a half. She will be trained more for a mile and a quarter and middle-distance races. She won't be trained as a Guineas filly."
