Dalkala an Opera star
Dalkala just got up in final stride to beat Tasaday and win the Prix de l'Opera Longines at Longchamp.
Trained by Andre Fabre and running in the colours of Godolphin's French arm, Tasaday was ridden handily by Maxime Guyon before assuming the lead two furlongs out in the mile-and-a-quarter heat.
However, Christophe Soumillon was just getting into stride aboard Dalkala and she rattled home in the final furlong to peg back Tasaday and edge out the grey filly in a tight photo finish.
Dalkala prevailed by the narrowest of margins for the Aga Khan and trainer Alain de Royer-Dupre with Roger Charlton's British raider Thistle Bird running a fine race in third.
Royer-Dupre said: "She's a very experienced filly and she tries as hard as she can. She's quite a complicated filly, and taking her by plane to the Breeders' Cup would be a big risk for her."
Dalkala hails from the family of multiple Group One winners Dalakhani and Daylami, and the Aga Khan admitted it would be a gamble to keep her in training next year.
He said: "In my experience, every time you leave a filly in training at five it hasn't been an advantage. She's very important to our breeding operation.
"She has run over a longer trip, so I didn't have any question that she would not get to the end of the course."
Godolphin's racing manager Simon Crisford said such a narrow defeat was hard to take but has high hopes for Tasaday in the future.
He said: "It was disappointing to have been beaten on the line like that but she has run a huge race.
"We'll talk to Andre about what to do now - I wouldn't think she would run again this season - but we'd like to win a Group One with her."
Thistle Bird is now set to head to the paddocks and Charlton was thrilled to see her sign off in style.
He said: "I'm so proud of her. Even by French standards that was slow, but in one more stride she might have won. That is her last race."
