Albigna swooped late to win the Qatar Prix Marcel Boussac for Jessica Harrington and Shane Foley.
The front-running Marieta (11/2) looked to have slipped the field when going a couple of lengths clear two furlongs out but the 4/1 winner was beginning her winning charge.
Bouncing back from a disappointing performance in the Moyglare Stud Stakes last time, the daughter of Zoffany was in front 100 yards put and powered away to win well.
Marieta held on for second ahead of Flighty Lady (7/1).
Andre Fabre's previously unbeaten favourite Savarin was well-beaten.
Sky Bet cut the winner to 14/1 from 25/1 for next year's QIPCO 1000 Guineas, Head of Sports PR Michael Shinners saying: "Albigna was an impressive winner. She handled the soft ground well to get her career firmly back on track and connections will no doubt be dreaming of Classic glory over the winter."
Harrington said: "I wasn't really confident beforehand as she has only run on good and good to firm ground, so we were going into the unknown. I was really not that confident going into today, but she showed the real Albigna that we see at home. I've only seen it the once and I thought she wasn't travelling that great, but Shane said afterwards that she likes to find her feet, which she did in her first two races. In the Moyglare she ran a bit free and was found to be in season afterwards."
The trainer added: "It is wonderful to win this race and I'm grateful to the Niarchos family for sending me these beautifully-bred yearlings - after the year we had last year with Alpha Centauri I didn't think I'd possibly have a year like this with the two-year-old fillies. I would imagine so (Guineas filly), she gets the mile well and she is a big filly and I'd imagine she would stay further than a mile.
"This is a 'win and you're in' for the Breeders' Cup and I know that it is very close to the heart of Maria (Niarchos), the Breeders' Cup, so we will talk about that after the dust has settled here. I would say she is probably top of the pecking order (of the stable's fillies) as she stayed the mile so she looks more like a Classic filly."
Al-Big-na price for the Guineas (Ben Linfoot)
Jessica Harrington’s talented Zoffany filly Albigna bounced back from her disappointing run in the Moyglare Stud Stakes to win the Group One Prix Marcel Boussac.
Found to be in season after her run at the Curragh, Albigna was on top form in Paris and swooped down the outside to land the spoils under Shane Foley in good style.
It was a quickfire Group One double for Harrington following Millisle’s win in the Cheveley Park last weekend, and she could make it a treble for her two-year-old fillies when Cayenne Pepper runs in the Fillies’ Mile at Newmarket on Friday.
General quotes of 14/1 for the 1000 Guineas look fair. Considering she was in season on her only disappointing run, that she had the class to win over six furlongs, including in Group Two company, on her first two starts despite the trip, and that she’s now proven herself versatile regarding ground conditions, she looks a major player in next spring’s Newmarket Classic.
Before then she could run in the Breeders’ Cup, an event her owners, the Niarchos Family, have a long and successful association with.
