Siyoushake came with a strong finish to land the Group 3 Prix Perth at Saint-Cloud this afternoon.
Crazy Horse and Maximus Aurelius were away quickest and it was the latter who towed the field along in this one mile contest.
Maximus Aurelius was still in front turning for home, with Royal Julius and Wanderina in close order and then Crazy Horse.
Into the straight, Show Day on the outside moved into the lead with Crazy Horse, but Siyoushake and Stephane Pasquier quickened well from widest of all and took a length and a half out of the field, with her rivals unable to close.
That margin remained in place as Siyoushake passed the post, with Crazy Horse just holding off Kourkan for second place.
The Freddy Head trained four year old Siyoushake, a daughter of Siyouni, had run with credit at Group 1 level last time out when fourth to Alice Springs in the Falmouth Stakes at Newmarket.
