Planteur, third in the Dubai World Cup on his previous start, looked like landing the Group One spoils for Newmarket trainer Marco Botti when he stormed past Don Bosco under Christophe Soumillon.
However, Stephane Pasquier had other ideas and brought the Jonathan Pease-trained Maxios with a telling run to get up in the dying strides
Mandour was third but Henry Cecil’s raider Beauty Parlour disappointed and was sixth of the seven runners.
Paddy Power gave Maxios a quote of 16-1 for the Coral-Eclipse Stakes at Sandown on July 6.
Carlos Laffon-Parias once again showed what a sure touch he has on the big day, as Silasol put an underwhelming return in the Prix Vanteux well and truly behind her, collaring Alterite late on under an inspired Olivier Peslier.
When the daughter of Monsun landed France’s premiere two-year-old race for fillies, the Prix Marcel Boussac, she had done it the hard way from the front.
This time Peslier was able to settle her at the rear of the field alongside stablemate Ferevia as Siyenica cut out a decent pace up front.
Turning for home both the Laffon-Parias fillies seemed to have an enormous amount of ground to make up but, in common with Arc day last year, the testing going really brought out Silasol’s will to win.
