Alain and Gerard Wertheimer's homebred Jumeau (Sea The Stars), a full-brother to four-time Group 1 winner Sosie, made a winning debut in Thursday's Prix de Fontenoy at ParisLongchamp.The 13-10 favourite broke well from an outer stall and stalked the leaders in third for most of the one-mile newcomers' heat. Easing forward in the straight, he quickened to the fore with 300 metres remaining and was ridden out to hold King's Road (Persian King) by a short-neck.“He travelled very well and gave me a nice feeling,” said rider Pierre-Charles Boudot. “He's a very nice horse and he's well bred, being a brother of Sosie. He has quality and did the job very well. He will improve, for sure.”Jumeau is the seventh of nine foals and sixth scorer produced by Listed Prix Coronation third Sosia (Shamardal), herself kin to three black-type performers headed by G1 Premio Lydia Tesio heroine Sortilege (Tiger Hill).He is also kin to G3 Prix Noailles victor Uther (Camelot), the multiple Group 3-placed dual Listed winner Anasia (Intello), the Listed-winning Copie (Iffraaj) and G3 Prix Daphnis runner-up Sosino (New Approach).
